2003 ranger 2.3 94,000mi
Got the codes, fixed the problems, 1) vac leak on IMRC fixed. 2) up stream O2 sensor replaced. 3) MAF sensor cleaned, new wires, new plugs. disconnected battery to clear codes. Started truck and drove about 5 miles at speeds up to 60mph, ran fine other than a little spark knock. Shut the truck off for about 2 hours and restarted had a CEL within three minutes.

Fuel filter?
second O2 sensor?

Only had the two codes to start I haven't pulled codes since I replaced all the parts today. What should I be looking for?

Thanks

Welcome to this forum! I've moved your thread into the EEC-V section. Find out what the code numbers are, and don't disconnect the battery.
