My 1988 Pontiac 6000 (2.5) with 125,000 miles has an issue. (Doesn't it
always?) Anyway, anymore, when I start it the car doesn't act like I'm
letting it turn over long enough. The engine starts, but it doesn't act
like I've let it turn over long enough even though I am. (I also hear a
slight belt squeak noise sometimes when this happens also during the
time right after I let off the key before the engine starts running.)
This morning, the same thing happened, only the car didn't start. When
I went to try the second time, the car turned over poorly, (the cranking
was erratic - there was no pattern) but I got it to successfully start
this time. It does not sound like a low battery, and that poor turning
over is the same thing it does when I have my stalling problems when it
does not like to stay running that I've talked about before. Once the
engine started this morning, it ran fine for two minutes, then it began
missing really bad just sitting there in park. It's missed like that
before, but not just while sitting there in park. When I gave it a
little bit of gas, it still missed. It's probably difficult to diagnose
over the Internet, but do you have any ideas what it might be? I was
thinking maybe the timing, but I don't know. Thanks.

Well unless you have changed the timing it is most likely not it. I assume
if you did modify the timing you did it according to the directions for your
car. Some require the vacuum to be disconnected to set timing. I assume too
you have changed the timing belt on the car probably recently, since timing
belts on newer cars need to be replaced about every 60,000 miles

if you haven't changed the timing belt ever, I would start with that. it may
be worn and skipped a tooth on the belt

I've not done anything with the timing with this car. This car uses the
timing gears, right? The one that's made with nylon that's known to
break over time? How serious do you think this is, and more
importantly, how expensive? I heard something about if the timing gear
goes in these cars, it will severely damage the engine. I also heard
that fixing the timing gears with this car is expensive. If this is
something that's going to be too steep, I think it will be time for me
to get a different car. Keep in mind that this car has lots of other
problems as well. I don't know what truth there is to all that about
the timing gears, cost, and severity, so what do you think? Thanks.

Yes the gears were made of a phenolic plastic type material, changed in
later years to metal, anyway this is a 'pita" job as there is a puller made
to get the gear off the cam, was a common problem back then, care must be
taken not to push cam out the rear of the block.
