Drivebability Issues

[teamitr]

I just did a 6 bolt swap on my car I kept the 2nd G head Everything is working Fine exept for when i'm in low speeds and i let off the gas pedal it pulls back it just does not feel smooth. I'm using the 1G cas... also at idle the car does not have a steady idle it has like a really small pop to it sort of like missfire, Now i have not switched the order of the injectors would that be my problem...?

Check your timing, your wires and plugs. That seems to be the most problems with low drive ability at low speed. Its not the injector timing, i dont even think you can change that. Also, whens the last time you replace the O2?

Injector timing can only be changed with a chip or ecu mod to my knowledge. How is your car modded if any or is it stock? I agree check out the basics like timing vaccum leaks etc. If you are running an adjustable FPR then what is your fuel pressure at? If you pull the 1 cylinder plug what does it look like if it is white then you are running lean and black is rich. Low rpm and running rich can act like what you are talking about. Also vaccum leaks can cause misses at low rpm. It would help you out a lot to hook up a datalogger. MMCD is a free one that works on most PDA's. It has the ability to save loggs and reproduce them in excel spreadsheets. I don't now how my car lived with out it.
