**brp57** · 09-09-2010, 06:38 AM

Just bought my first trans am 2 days ago (98 trans am a4 82000 miles) so I am a nebie. Anyways I already got a check engine light, got it checked and was p0131 and p0151. I know its the 1st o2 sensors before cat both banks. Going to check maf and clean it also. Need some more help please. Car idles fine and revs fine. Seems like its not pulling and missing when I get on it. Read something about a fuse to check and also injectors....?
Also forgot to say that the engine coolant temp. gauge I noticed dosent get warm. Only gets to 1st mark? Is it a sensor? Could that cause this problem? Please help!

if those are the only codes..and not being followed by bank leans ...it looks like a sensor related issue

Car is completely stock.

If the car is completely stock, then you probably need 2 new O2 sensors and maybe a thermostat for the coolant temp issue.

Yea I installed the 02 sensors tonight and cleaned the maf. Wow was the maf dirty!!! I couldn't believe it. I will be changing the engine coolant temp. sensor tommorrow and then I will fire it up and see what happens. Wish me luck.
