I just completed my 165-730 swap and my car runs very bad. The engine shakes violently, it won't tach up, even in neutral. No codes either. Anything come to mind with these symptoms? I will get a scan for you guys in the evening. Thanks for any input.

 

Any codes? What mem-cal are you using? Check all the pins also.

 

No codes. I am using a memcal from a 90 vette. I have triple checked all the repinning. Here is a scan, all the fields that are in a MAF system look fine, I haven't worked with a MAP system to know what normal values for it is. http://www.fbody.com/members/Formula355/runbad.csv

 

Do you have a vacuum gauge?

I would aim for IAC counts under 25 with car in park, warmed up, no throttle applied. I have had some weird instances where an obnoxious IAC caused by other problems led to high counts and my vacuum at idle dropped about 5 to 6in-hg lower than it should have been. Makes for some rough running.

EDIT-Maybe not. I took a look here...

and it appears that your vacuum reading would be considered normal. I am more used to seing kPa dislayed instead of voltage. Pardon me.

 

My problem isn't just at idle. Idle vacuum is at 9" hg, which seems really damn low. I never though to check it with my MAF system.

A memcal for a 90 Vette is for a 727 not a 730. There are differences between the SD Vettes and SD F-bodies and I can't predict if the SD Vette Memcal will work. Why don't you doit right and just get a F-body memcal?

Of course you have reset the IAC?

 

I found the problem. The passanger side injector fuse was blown. I was able to touch the passanger side header tubes after a short trip. Runs like a raped ape now. As for the memcal, it needed to be special ordered from gmpartsdirect so I just bought the vette memcal from a local guy, sometimes I hate having a high maintenance/mods daily driver. Thanks for all the input in both of my swap related posts, finally running with the 730 crowd.
