Engine Performance problem
1993 Chevy Corsica 6 cyl Front Wheel Drive Automatic 142000 miles
I have been working on my daughters car. When its cold it idles over 1000 rpm until it warms up. I found 2 codes in the system one being tps too low and egr bad reading. No check engine light is on. Also the other day on her way to work it died and would not restart. She was at a stop sign when it happen. After a short while it started again and was able to make it home. I hook up a mt2500 snap on scanner and check the codes that are listed above. I also check the sensor data and it show only 75 rpm but the desired idle showed 825 rpm I changed the crank sensor it did noot help. I aslo change the iac, tps and I do think I solved the idle problem I wont know until tommorow. When it has cooled off. I also check the fuel pressure it went up to40 psi when turing the key on and then styed between 36-40 psi while running. Slightly low according to specs. Have I miss anything?
