Mom-in-law's '88 240 DL
It drove her to work just fine but would not keep running when she wanted to leave.
Here are the symptoms as I see them.
There is spark, fuel & compression.
When the key it turned, it catches and then immediately dies.
Sometimes I can keep it running for awhile by giving it some throttle but not always.
When this happens, it runs very rough with what sounds and acts like multiple backfires into the intake manifold.
I removed the upper timing belt cover and the marks line up properly (cam gear marks & crank balancer marks). There appears to be some oil on the belt but there are no missing or chewed up teeth.
I considered the IAC valve but wouldn't it run OK with throttle and just have trouble at idle?
Car had tune-up in August w/new wires, etc.
Wires are hooked up 1-3-4-2.
There are no holes in the air intake hose that I have found nor are there any disconnected vacuum hoses that I can find.
I have not checked all the diaphragms yet to be sure they are sound.
I am now at a loss short of removing the timing belt parts and see if the key(s) is stripped.
Any other ideas?
Thanks in advance.
