Hey hey, sucks i have to write this. I have a 91 hatch, stock KA, Walbro 255, stock FPR, New fuel filter, Newer injectors. When i start the car dead nuts cold it will idle at 1300ish and slightly miss/hesitate. Once warmed up the car will idle as if the MAF sensor is unplugged, jumping from 50-1100 very fast and then die out. Now when i drive it pulls hard through all the gears but as soon as i put in it neutral 9 out of 10 times it will instantly die. If it doesn't die as soon as i come to a complete stop it will die. I have cleaned the IACV and bench tested the AAC selinoid-can't spell, it also had 32ohms of resistance. Also today i unplugged the AAC connector and it idled better for about 4 minutes and then died out. Plugged it back in and same deal. My TPS sensor is good and i don't believe that it's my MAF. Also the IACV-Air regulator and FICD valve are bypassed when warmed up, corrrect? Any help would be awesome.
