So the oher day my girlfriend was at a drive-thru in the Intrepid waiting on food when the car stalled (oil light came on but that was the only light). Later that day I waspicking my brother up from work, and was at a stoplight when it stalled on me. Just a slight shutter and then dead. Started right back up, although as I entered the highway on-ramp it reved higher than it should have, but it was fine after that.
The problem is that it's been fine since then. Took it to the mechanic on Monday and they were unable to get it to stall. He suggested either the fuel pump or the timing chains. Today still no luck, and my girlfriend needed it so she picked it up and it was problem free.
So..based on queries on Dodgetalk, my own guess, and the mechanic, here's the possible issues listed:
Timing Chains
Fuel Pump
Crankshaft Sensor
Dirty idle air motor
Throttle Body
Fuel Filter
I could be wrong, since diagnosing a problem isn't my forte, but I would think the throttle body would be ruled out, since it idles perfectly all of the time and the revs are always properly modulated, with the exception of those stalls. It's not like the Shadow, which I know needs a throttle body, as it idles somewhat high, never maintains a steady idle (fluctuates a 100 or so rpm), and usually wants to stall when it's cold or sometimes going in reverse.
Fuel Pump...I don't know the symptoms of a dying one, but I would think once it goes it goes and won't work anymore...not most of the time and sometimes stop working. I have no idea though.
The sensor, motor, and filter I'm not sure where to check/how to check as the repair manual I have doesn't say for any of them.
As for the timing chains...I know they need to be replaced, as it's about that time (almost 200,000 miles), and I planned on doing it soon anyway (which I think/hope would get rid of that sound I mentioned several months ago). My question is...can they make a car sall by them and the guides/tensioners being worn?
Really the only thing keeping me from having it done now is the question of the fuel pump and if it's linked to the stalling or not. I have the money to replace the chains or the fuel pump but not both. I just hope it's not the fuel pump.
Any advice/thoughts/other possible causes would be great. If possible I'd like to get this remedied before this weekend. Thanks guys!
