P0131 and p0151 help
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 the car is completely stock, then you probably need 2 new O2 sensors and maybe a thermostat for the coolant temp issue.
