I bought this off e-bay and installed it. Now I'm having trouble hooking up the stock throttle body cable. Can someone tell me, where there is only a slot for a cable, is that where the TV cable goes?

I'm pretty sure it's missing the pegs to hook on the stock throttle cable. Was this a machining error and does anyone have any instruction on how to rebuild a throttle body? (I'm thinking that I may be able to install my stock throttle body lever on this somehow.)

HELP! Not sure if the seller will take this back.

that is a 89-92 throttlebody and uses a wrap around cable gm 10163822

http://www.gmpartsdirect.com has the cable for a good price.

Given that on your new TB the linkage is able to be unbolted , you could contact Lingenfelter and get the correct linkage for your year
On most TB's you can't easily swap the linkage , stock it is welded on ; grinder and welding required

The accel (prestolite performance) lingenfelter throttle body was contracted bye kinsler fuel injection and no parts are available for the 74191.

Well, since I don't have cruise control or automatic, I've sent the photo to Lokar to see if they can sell me a throttle cable to make this work. I knew it didn't look lim my stock one , but I'm just hoping now that they will have a solution for me. I'm not sure if the stock cable for an 89-92 will fit as the guy at the parts store brought one out for me yesterday and it had a ring to fit over a peg. This throttle body lever has no peg

Was a throttle cable , not a TV cable that fits like that?

If it was a throttle cable , then it was the wrong one
The cable with the part # linked above has a steel pin crimped on the end of the cable to fit in the hole you show. Cable then lays in the groove
Get them to cross reference that part #

Stock 89 - 92 TB has exactly same linkage as your aftermarket TB

It "looks" more like a LT1 Tbody to me... Maybe I'm waaaay off tho..

why would you go with lokar on a thirdgen ? you will have too buy a tv cable double stud and throttle cable. Oh well your coin

LT1 uses similar style linkage to late TPI; later versions with 4L60E did not have the TV cable hookup

I live in Canada and it's $45 for it at my local GM dealership. When I went to see a Dorman cross over part number 16648 it did not have that stud on it.

http://www.rockauto.com/catalog/raframecatalog.php

And I know that Lokar was supposed to include a stud or something to fit the 89-92 throttle body.

That's the hard thing about living in Canada. Or basically anywhere but the USA. Although we have a free trade agreement in terms of NAFTA, if the part wasn't made in the USA (because it was offshored in Asia) I've got to pay duty and then taxes on it. And if I buy it here, well, they mark it up so much it's kinda stupid.

Nelz

Would you happen to have a picture of that particular throttle cable on your car?

Nelz

Are you sure that's not an LT1? http://www.hotrodlane.cc/Streetstories/choosingtpi2.htm

That street and performance throttle body for the later TPI's sure looks different. Actually, looking at your idle air valve, that's definitely not a TPI throttle body.

Nelz

Ok, now I'm convinced that throttle body I got off ebay was for a 94-97 LT1.

http://forums.corvetteforum.com/c4-t...fferances.html

To make it work, I'd need to change the cable. The 94-97 LT1 throttle bodies don't have a provision for TV cable and cruise control. (I'm guessing somehow the PCM took care of that in those later years somehow.)

vetteoz

iTrader: (13)

Makes no difference ;
it is the linkage style we are looking at here ( and anyway you can swap a LT1 IAC housing on to a TPI TB and vise versa )

Which means you would have to drill a hole in the linkage to mount the stud

As I already said , the later cars had a electronic trans ( 4L60 E ) that was controlled by the PCM

looks like your throttle body lever is marked where they started too machine for the tv stud. Im not sure if the tv stud from holley or jegs is long enough but it would be easy to drill and tap threads.

Nelz

Be careful if you're buying from rebel performance. I didn't notice this flaw right away and since it took a few months to get the motor out of the machine shop my "return" period is over.

I'm hoping that Eric at rebel performance will help me out. We've been e-mailing back and forth about this.

I'll let you guys know how it works out and post here and in the vender section after.

85-88 on right 89-92 on left .. If you have your original throttle body you can grond down the rectangular area that the shaft passes through the lever then remove it and swap it onto your other throttle body. That is why on yours that bolt is there or you can buy the correct lever assembly for 85-88 and swap it out too.

Nelz

The correct part number for that throttle body is 74191L (I guess the L is what changed the designation between the TPI and the LT1)

Nelz

I'm debating that. I'm wondering what Eric at Rebel performance will say first. They have a 15 day return policy, so if you're not working on the motor and don't catch it, you can't ship it back (and in Canada on regular ground, I don't think it would get back to them in 15 days anyways.) Also, take a look. The throttle body lever on mine is missing those 2 studs that stick out of the throttle body levers because the later LT1's didn't have cables to control the cruise control and transmission.

Nelz

and where the heck am I going to get just a throttle lever from anywhere for a TPI? I've been hunting and can't find a part number or anything. It seems it was just buy the throttle body and that's it.

I have a junk 86 throttlebody, tomorrow I will see what its like after it is removed from the shaft for you. but I am certain if you remove that linkage if it is like my friends TPIS throttle body it has a rectangular hole in it. His came with early and late throttle linkages so was just a matter of unbolting and using the one that was correct for his 1990

Your car is a 85-88 right?

Nelz

It is, but let me see what the guy that sold it to me says first. I don't want you to take off the throttle body lever for nothing.

1991Syclone

Here's the style he's selling on eBay now.



These versions have the provisions for the LT1 (I believe) throttle cable and linkages. I'm looking to find a source for a TPI version to put on my Syclone.

I've contacted Lingenfelter directly, but I believe they aren't going to be much help. There is also Accel that sells something similar and possibly Arizona Speed and Marine.

The last option is to do the swap. I haven't gotten far enough into this to figure out if it will work or not.

I know this is thread is a few months old, just wondering how you made out with your issues?

Nelz

It completely sucked. I had to ask Accel and they gave me a list of their suppliers. However it was Lokar that gave me a cable that would work. I still don't know if it works yet as I'm still not done.

I would seriously e-mail eric@rebelperformance.com and make sure that he will actually send you a throttle body with that throttle body lever before you buy.

Since you've got a non-computerized automatic, you're going to need those studs.

1991Syclone

I went through the same process. Accel sent me contact info for a speed shop that might have one, but I haven't heard back from them. That picture is of the throttle body I have. I could swap throttle cables, but the biggest issue is the TV cable for the transmission.

At this point, my only option is to try the swap from the stock throttle body. That requires drilling the swaged end of the throttle shaft and doing the swap. I am going to try and get to it this weekend. If all else fails, I'll resell the TB.

Nelz

Did you already buy that throttle body? Did it NOT have the right throttle body lever? When did you do it? Can ebay buyer protection help you? If they can, ask for a refund.

You'll notice that Edelbrock is who Lingenfelter now uses for a 58mm throttle body for LT1's.

1991Syclone

Correct, it doesn't have the correct linkage for my application, but I'm not saying I want to return it. I just double checked the auction and it does say it's for TPI, which is incorrect. These are LT1 style throttle linkages. I'm not sure he understands the difference between the two.

I am going to try and swap over the linkage. It it works, great, if not I'll resell it to a LT1 owner. Honesty, I should have looked at the pictures closer and compared them to my current linkage before I bought it. The pictures are exactly what I received.

I haven't gotten around to swapping out anything yet as I have other projects on the go, and as far as I know, nobody is selling the TPI linkage.

Nelz

He knows the difference between an LT1 and TPI linkage. I pointed it out to him in a few emails after this was posted. And I forwarded this page and the vendor review page to him. If its still within 15 days ask him for an exchange. He told me he would exchange it and then pulled that offer from the table because it was beyond the 15 day period. Or open up an eBay dispute as that item had buyers protection under item not as described.

Nelz

And he certainly knows why this will not fit a TPI with an automatic! I made this very clear in my email. There's a larger market to sell to if it is advertised as a TPI part (if you have a manual it works) vs a 94-97 LT1 part

1991Syclone

I did contact him and he noted that he doesn't have any TPI linkages, which is probably why he decided not to do the swap with you. I also went through the chain of command trying to see if someone stocked a TPI bracket with no luck. So, since I wanted to use this TB, last night I took a spare TB, drilled out the pressed end of the shaft and removed the stock TPI style linkage.

I did have to do a little grinding to get them to fit over the threaded rod end on the new TB, but it didn't take much to get it installed. Here's the final product.

I just bought a Lingenfelter 58mm throttlebody for 85-88 tpi
I'd like to trade the bracket for the 89-92 style so I can use it without changes. If anyone wants to swap, PM me
