Hi im new to the forum and I just picked up a 94 3000gt sl for my little brother. it's his first car so I want it running perfect. My problem is I start the car It will idle at around 1400rpm-1500rpm and then after 2 to 3 minutes it will drop the idle too 400-500 and then die out with no cel.. In that time before it dies I'll try and hit the gas to see if that helps but it feels unresponsive. the car will fire right back up every time but continue to have the same problem. I replaced the iac and the tps but still no changes. if I unplug the maf it will idle but then die out as it should. Could it be the MFI? When I turn the key and start I don't hear any clicking coming from the MIF. I know i should pressure test but I'm having a hard time finding the adapter. any help is greatly appreciated!!!!
