Hey everyone I recently found a good deal on a 1979 Pontiac Trans Am that has been modified quite a bit and I couldnt pass her up. Im having some trouble getting this car to pass emissions. Here is the list of known modifications:
Holley 770 Street Avenger carburetor Edelbrock Performer Intake Lightweight pistons & rods Comp Cams xtreme energy cam & lifters Hooker Headers Flowmaster 30 series exhaust TCI transmission 3200 stall
The 403 Olds engine has a fresh rebuild and has been bored out. I took her in for a smog test the other day and she failed miserably on the HC portion (500 max, read 3100!). I had the timing set the day before and it was running great- no obvious ignition problems. The car does idle very rough and Ive noticed it has a tendency to die when put in gear (esp when cold). Any idea on whats going wrong here?
thanks, Greg
