I pulled the codes on my car today because it is missing under light throttle and its idleing at about 1100. I pulled up codes: 85, 87, 96, 29, 31, and 66. I know 87 and 96 has something to do with the fuel pump relay, but wouldnt my car not be running if the relay was bad? and code 66 has something to do with the mass air voltage, is there a fix for that? Code 31 has something to do with the voltage on the EGR valve. Do you guys know any fixes to these codes?
Thanks in advance
