hankosolder2 Posted August 28, 2011 Share Posted August 28, 2011 I decided to start a new thread; the old one seemed to fizzle out and had an embarrassing misspelling in the subject header! I'd really appreciate suggestions- I'm getting desperate to fix this. '98 OBW 5-speed, 216K, 2.2 swapped about 5 years ago. It has started doing a variety of things- Sometimes bucks/ stalls on takeoff. Once in a great while stalls at idle, hot or cold. Sometimes loses power (all cylinders dead) while accelerating, then power comes back on. Sometimes light "trailer hitching" trace miss when cruising at a constant speed. Sometimes it will run perfectly for an entire 45 minute trip. No cel is on, no stored codes. I put a scan gauge II on it- coolant temp reads out normal, TPS seems OK, it goes to closed loop OK, no out of range or erratic readings that I notice. It's hard to get a reading while it's doing it though- the scan gauge updates pretty slowly. I tapped on the MAF. Plugged and unplugged all the connectors on the engine harness, wiggled wires with the engine on. Any thoughts? Thanks in advance!

Rooster2 Posted August 30, 2011 Share Posted August 30, 2011 Possibly bad gas?? A tank of gas that has some water in it, will cause these symptoms. Add some "dry gas," to the gas tank, maybe that will help. Can't hurt! Quote Link to comment Share on other sites More sharing options...
hankosolder2 Posted October 2, 2011 Author Share Posted October 2, 2011 It finally threw a code- MAF sensor low. A good used MAF sensor solved it and it's been running fine for over a week now. Very relieved. Just thought I'd post this to help anyone who has the same symptom down the road. Nathan Quote Link to comment Share on other sites More sharing options...
