Got cel so went to autozone and have codes read. They were "2" 0157. cel came on suddenly when accelarated for about mile or so on a highway . I have 89k miles do you think i should replace them? or i can simply reset the codes. By the way this is second or third time i got them in past 3 months under same driving situation and have been reseting them. I have recently replaced plugs with campion and throttle body was cleaned by mechanic during timming belt replacement.
rodeo 99 v6.

I'd replace it and hope that's the problem.

any particular brand i should look for or just buy the cheapest?

I used bosch. Just make sure it has an OEM connector. Any parts store should have a direct fit.
