Hello! I?m new to the forum and thought I?d give it a try. We are having some trouble with my daughter?s 1995 Chrysler New Yorker 3.5.
For a recent no-start problem, we replaced the crankshaft and the camshaft position sensors and one additional sensor (I can?t recall which one it was and don?t have a copy of my invoice). The problem turned-out to be a failed or stuck tensioner for the timing belt. After those repairs, the car has run flawlessly for a month and about 500 miles.
What?s happening now is that the engine dies upon stopping at a stop sign/signal. This is inconsistent. Sometimes it happens and sometimes it doesn?t. If it does die, (so far) it never fails to restart and run perfectly. Sometimes, if it doesn?t actually die, it?ll ?stumble? a little and then smooth right out. In, say, a five mile trip, this may happen, at worst, 5 ? 6 times . . . . . and, it may not happen at all. Here at home, it seems to idle without problem (at about 1000 rpm per its tachometer).
My immediate suspicion was a loose battery cable. That?s been all checked-out, thoroughly cleaned and re-connected. The problem persists. The engine is not ?throwing? any trouble codes. I have done some preliminary checking for vacuum leaks and loose connections . . . wiggling connectors.
I?m probably beyond my own ability a far as diagnosing and repairing this. What I?m mostly looking-for is your ideas for things that might be suspect and need further checking. I know, even for a fully-equipped and experienced mechanic, how difficult this sort-of thing can be unless somehow it will occur when he actually has if hooked-up to his test equipment. Any ideas or similar experiences that might help us? Thanks. Don
