Running Rich, supposed MAF problem.

[ArcherV20]

When I purchased the car it came with an S14 SR20DET - he had notified me that it was running with bigger injectors and that the ECU was tuned to run with a different MAF. However - he's not sure which MAF that is - the car when idling does shake a bit and causes the engine to run a bit rich.

He told me to fix the problem I'd need to swap the spare ECU he was going to give me and find some stock injectors. Anyway - I was wondering how I could go about finding the proper MAF in order to have the car running smoothly. I don't want to go down to the lower injectors and go through the trouble of swapping the ECU. If it's as easy as finding and installing a Z32 MAF then I'd rather do it that way.

Thanks everyone.
