I just purchased a 1999 GST. I am new to the DSM world. The car has been running very rich ever since i brought it home. The only upgrades the vehicle has is an Injen intake, an Apexi catback, and an Apexi S-AFC 2. The only code which the vehicle has thrown is a P0100, which is for the MAF sensor. The previous owner says that a new MAF sensor was just installed right before i got the car and it tested fine. Also another related problem is that under wide open throttle condittions the car wants to cut out from 1800-2800 rpms. The TPS may be bad. When testing it, it fell well short on a resistence test, but i just wanted to make sure it wasnt just a fuel issue before replacing it. The fuel pump is quite loud and can be heard running constantly, dont know if that is an issue or not? Is there a base line fuel set-up for the S-AFC 2 that has worked well for anyone with a stock 2G GST? Any advice is much appreciated!!! Thanks!!!
