New here, have code 114, 335 KOEO

[PatrickJ]

I just bought a 95 limited explorer, 500 bucks, it has a slight hesitation most noticeable until it gets up to 50 mph or so, I'm sure its still there just less obvious when going faster. So I warmed it up , shut it off and retrieved codes KOEO 114 and 335, it also gave me codes 214 and 332 after that, I think I will just replace the IAT sensor sense it's cheap, but after that I'm not sure the EGR sensor looks expensive, hoping someone more experienced can guide me along .

KOEO 335 is almost certainly a fault in the EGR sensor circuit: whether the sensor itself or a fault in the wiring between the sensor and the PCM. If you get a wiring diagram and a volt meter, you should be able to check the wiring without too much difficulty. If the wiring checks out, then I would probably just replace the EGR sensor, as they seem to fail somewhat frequently.

Welcome to this forum! How did you retrieve the codes? Do you have a code reader or did you use a jumper wire to count the flashes of the check engine light?

I used a code reader
