I know someone with a deep quary to drive into, but I'm using that as a last resort!
R2's problem started about a month ago, surging while driving down the highway. The car would seem to die, you'd take your foot off the gas, reapply and it'd be fine. This would happen once in a blue moon, maybe every other week of so.
Then, one day sitting at idle (actually while we loaded my husband's 740 onto the car trailer...) it shut itself off. Restarted with no problem.
The next day on the way to work the surging problem was very bad, to the point where I had to pull into the breakdown lane a few times. It did keep running, but gave some pretty healthy backfires. Later, driving though town, it stalled at a traffic light, but restarted.
Next day, it drove to work fine with no problems, but stalled on highway coming home and I couldn't get it started again. My husband came to rescue me, and we found a corosion on the AMM plug. Wire brushed it and sprayed with some PB blaster and I was good to go. We even took the thing 3 hours away camping. BUT, we almost dind't make it home - loose wire in the plug.
So now the car's been acting up for a month, lots of backfires and even melted the plug on the AMM a bit. But, we've fixed the loose wire and things seem good, I take it to work. The SOB dies and I have to get it towed home.
I've replaced the connector on the AMM, but am wondering if the sensor itself is on the way out, or if I have some goofy electrical problem somewhere along the line.
We've pretty much ruled out fuel delivery problems, both pumps run, relays and fuses all good. There was definately a loose wire on the AMM plug (red/white striped) with a bad connection, but I"ve fixed that now.
Help oh great brickboard!
