Title: About time....
Post by: tireshredder on July 14, 2010, 01:04:04 AM
Long time, no post.  Been down at school, so I didn't get to work on the car much this last year.  Came back, and now I got her running.  Pulled it out of the garage tonight for a test drive and noticed a few things, one thing in particular.  So I ask the almighty FTCF board for help. ( :bowdown: We're not worthy! :bowdown: )

Anytime I get on the throttle, it stumbles really bad. Doesn't matter if I ease on it or get on it harder.  Doesn't do it as bad in neutral. Is a bit rough idling, but not too bad, like it need fine tuning.

Specs:
351W Truck motor
E7TE heads
Truck Cam
Cat-less dual exhaust
GT40 upper and lower
24 lb injectors
96 Cobra MAF
70 (or 72) mm TB
BBK Swap headers
Stock AOD
C3w Computer (supposedly reprogrammed to 93 Cobra specs)

Any ideas?  Fuel pressure is good.  Ran for about 10 minutes last night, another 10 tonight.  Don't know if the computer has learned what it needs to yet.  Any thoughts will be appreciated.

It's been in the car for about 2 years.  It is a fresh rebuild.

Gas may be a bit old, but we did drain the tank.  It's a year old at most.

Gas does have a tenancy to go bad rather quickly nowadays .
 A can of seafoam in the tank might not be a bad idea .
 I had a motorcycle not even run on gas that  was 4 months old a while back .

Title: chip tune

You will likely need a chip with a tune for those mods. Will that mass air work correctly with the tune on that computer?
