CEL issues - what I've done, what else should I do
Thanks for any suggestions - First time Ford/Ranger owner, 2002 XLT, 2WD, 3.0, 165K miles. I have owned it now for 1 tank of gas and it starts running rough, then check engine light comes on. I have the codes checked 3 times: misfire on 4, 5 and 6 cylinders, OS, MAF, too rich/lean... and I don't trust any of them. So... I clean the MAF, IAC, and seafoam - lots of carbon everywhere. Now when I am idling I can't get the RPM's over 3000. I am done for the day, will try more tomorrow - any suggestions on what to try next - the one shop wanted to give me a tune-up, but the wires look pretty new, and I am thinking why would you change the wires and not the plugs too. Any suggestions would be appreciated.

Pull the spark plugs and have a look at them. This will give you a pretty good idea on how the engine is burning fuel. Compression check, vacuum check, replace the plugs, clean the throttle body, check the PVC valve, EGR Valve, and clear the codes. You might have a problem with the cam snycro. I'm no computer guru by a long shot but Misfire is a symptom.
don't listen to me though, we still have not figured out why my engine runs rough and idles too high.
Good Luck !!

i havent done any work on the 3.0 but my buddy has a v8 and we changed his spark plug wires, head gasket seal, and spark plug. that fixed his problem... it was the same as yours...
my automotive teacher said that if you plug wires are touch any kind of metal it will cause an electrical short... so the power never gets to the plug... he also said it depends on how thick the installation is on the wire
