well that the question, is it?

 

uh, no.......

 

wow never knew that thought it was it dont shake much but if i pop the hood i can see my motor shakeing. that from my timeing right?

 

I thought I had an idea, I do notice that around stock idel 800rpms it sound like every part of my car vibrates the best and you can hear every lose plastic pannel rattle. but around my set idel of 1000rpm I dont hear anything. Kinda like 800rpm is the right note for my cars tuning fork.

 

Check your motor mounts.

 

I second that.. I've got one motor mount that's kinda worn...doesn't even allow the engine to torque much, hardly at all..but it's worn enough that it translates engine vibration from rough idling all through the car I think. Shakes the steering wheel, the doors, the dash...everything.. You could also look at why it's shaking...give her a nice tune up... I'm thinking I'm gonna get new, cleaned fuel injectors soon...I'd clean my existing Multecs, but I hear Multecs are crap injectors so I'm gonna see if I can't grab me some F0rd injectors that'll work...hopefully they've got the same setup and everything and can be run without any modifications to the fuel delivery hookups...
But, what have you done to it in the way of replacing sensors, and ignition parts?

 

motor mounts $hit glad i found out now, before my car goes in the shop on monday. now i can tell him to check that out to thanks. does it cost alot to replace them??

 

Parts are cheap, but a PITA to put in, or atleast on my 91.

It may cost a small bit becuase of the cussing factor, and it is somewhat time consuming.

 

Check mounts, and IIRC, you got a carb'd v6, right? I'll bet some of your rough idle could be -

A) vacuum leak. Check/replace all your hosing.
B) carb needs cleaning. Seriously, if the idle feeds get gunked up (scientific term there ) then it'll throw the calibrations waaay off, giving you a rough idle.
C) motor mounts.

Carbs can be a nightmare to work on, but basically, they are EXTREMELY simple devices. I'd bet a carb rebuild would do wonders, with a general tune up. TomP's got a GREAT one!

 

ya i am goin to get all that checked out but i have this feeling its not my motor mounts, and its my timeing but i will find out. my carb was just rebuilt this year, i am goin to clean it on monday though. when i was putting my carb back on i snap one vacume line i plug the whole with a screw though i have no idea what that line was for. oh i have 1 more question, does my car have a MAF??? if so is it that round black thing in front on passanger side??? and how do i know if its broke, my old problem came back.. ..when i slam my peddle 2 the floor it bogs for a bit then goes, is it from the MAF???mass air flow, thats what carb guy told me?

 

Um, no, you have no MAF, or MAP. Your bogging seems like you're running too rich... post a pic of the engine compartment, and we'll try to see what we can find for ya

 

i replaced mine, takes a really long time unless u know wat ur doing. i paid 60 for 2 motor and a tranny mount but that was with a 40% discount. and in canada also. but after i installed tehm my car shakes like that to.

 

got is out the shop none of my mounts where gone well the bolts that hold my tranny in where like half out but got that fixed. just turened out my carburator was off a bit and so was my timeing now everything is good no more shake. but the boggin is still there, i dont have a pick of it. but its on the passanger said in the very frount it black round and has 3 wire goin in it on the top. the carburator guy say thats what it is, the black thing like recycles gas or something like that. but i am so sure he said it was a mass air flow. could be wrong. oh i will try to get a pick of it asap. thanks for any help u all can give me.

 

Sounds like he's talking about the EGR valve.... If you DID have an MAF sensor, which I believe you shouldn't as others have said, it would be mounted above the carburetor...
A pic would help..I haven't looked at carbureted V6's....and I havent looked much at vacuum EGR's, but yours should be a vacuum EGR and I didn't think vacuum EGR's had any wiring going to them, only digitals...hmm...

For the bogging part..uhm..if your carb is tuned now..how's your ignition? Cap/rotor, plugs, wires...forgive me if you already said you replaced these.. But if the ignition is not at its best and it's not producing enough of a spark then it can rob power, particularly low and mid-range I think, because it's unable to burn up all of the fuel mixture in the cylinders...

 

By the way...what you said earlier reminds me of when I first got my Camaro over a year ago...it was my first car..well, STILL IS my first car should I say...but it had a rough as hell idle...but I just thought that was because it was a bigger motor (Yeah, a 3.1 was big to me at the time..I was used to my dad's Cavy with a 2.2 or 2.4 4-banger, I forget which). I assume the rough idle was only because it was powerful. Hehe...boy was I wrong!!

 

i will get a pic of that thing this sunday with my friends digital camera. my carb was done less then a year ago, my wire and plugs, i put in almost a year ago the plug are real cheap my wires are niehoff >spelling is wrong i am sure but the guy told me they where the best. so ya any way, my rotos and brakes where just done 2 days ago, same with the timeing. (i can do burn out why better now, luv 2 show off) ya anyway i dont really want to change the plugs and wires because i only have 5 months left of this motor and i dont want to do anything that cant go on the v8. so ya just need to make it for 5 months, unless i can find some one to buy it, it only has 55K on it, its a shame i know. ya so i will post the pics asap.

 

55k on your current motor? That's PHENOMENAL for such an old motor.

 

I did the SAME thing with my first car - my '77 Bird with a 354 Pontiac in it. Figured it was 'oh so powerful'. Dead wrong (170hp/280lbs-ft torque).

Now she idles like a kitten, and screams like a banshee

 

Heh...yeah 170 hp isnt a lot, but 280 ft lbs sure is! Thats what makes it a V8... And yeah...my car idled like **** when I got it. It still does..but it's way better than it was. Still has this very irritating vibration and shimmy...I'll get it ironed out sooner or later....I figure fuel injectors.

 

You know that sounds a LOT like my dad's old car...except I think he said his had like 130 hp or so....but over 200 ft lbs..it was a V8 too, from the middle of the emissions era. Kind of sad.....my grandparents Buick Skylark would beat it flat out...but I tell ya, that car, whatever it was (he doesnt remember and I was too young to) could out-climb the Buick any day...it went up hills like nothing at all with that torque. The Buick had a 2.8 V6 I think by the way!

 

k i no its been a while 4 me to get the pic but i found one on this board, any why is this a MAF and is this the reasion my car dogs when i put the gas 80% to 100% to the floor???

 

oh ya it the round black thing but i am sure mine just has 3 wire.

 

Yes, the round black thing is the MAF. MAF's cause all sorts of problems when they fail. Couldn't tell you whether it could be causing your particular problems, or how to check, because I've never had to deal with one.
