2003 ESV Idle issue
Hey guys, new to here and I have a problem thats driving me INSANE. My 03 ESV has about 230 kms on it and I have a bad idle issue. Regardless of operating temp it will flutter idle between 100-700 ish rpm and stall out at times. The CEL light is on, I can't remember the exact code but it reported back as a MAF problem. I replaced the MAF and I still have the light and still have the idle problem. Do you guys have any ideas here? This truck has been nothing but a HUGE lemon since I owned it and this is just one more thing that is driving me nuts and I am really trying to figure this out so I can drive this truck without worrying. Thanks guys.

Assuming the new MAF isn't defective, the only other possibilities are a connector/wiring problem, or a faulty PCM.

I hate to be obvious but did you clean the throttle body??
Mine would idle like crap when I first got it and I had to clean the throttle body
