Thanks for the info. It was a great starting point. We did check the crankshaft sensor and found it to be OK. I was also told sometimes the waterpump can leak and short this sensor out, but we found no leaks.
However, something I didn't think about was checking the fuses. I had a bad key chip and thought the problem might be in the ingnition switch even after buying new keys. What I found was that over time the fuses had vibrated part way out with the ingnition fuse the furthest out. These were tightened and so far I have had no further problems. Thanks again.

the 95 buick was missing so took it to repair place and they replaced plugs wires fuel filter and flushed trany fluid and cleaned the fuel injectors. it has 57,000 original miles on it and it was getting 20miles to gallon after tuneup it now get 15.79 per gallon or 16 miles only what could be wrong? Thanks shirley

Took the buick back to auto repair and they checked it out because it was losing 4 mile per gallon after tuneup and they said they didnot look at the update bulletin, so this time they did look and say they think they found the problem after the tuneup and fixed the problem. Too soon to tell.

Did they say what had been done wrong or what was missed that would cause a drop in mileage? I am finding that hard to believe that there was something in a bulletin...

I have a 00 park ave with 110,000 miles. it drove fine untill last night the thing just started sputtering and then died out. It still starts up but does the same thing unless the rpm's are up high. the wierdest part about it is that the check engine light didn't come on. I tried to diagnose it anyways but it came up with no codes. I have replaced the spark plugs and wires, the coils looked fine,checked the pcv valve and that also looked fine. checked every vacuum hose that I could find and cleaned most of the sensors. I have also replaced the fuel filter and put in some fuel injector cleaner but it is still doing the same thing
any help would be greatly appreciated!!!!!!!!!!!!!!!!!

The only thing to try that you are able to do yourself without a fuel pressure gauge is to remove the wires from the MAF sensor on the throttle body. Disconnect that leads. And start the motor. See if it will run without it connected.
My other thought would be fuel pressure. It's a little young in miles and years for the crankshaft position sensor or camshaft sensor to be bad.
Note that pulling the wires for the MAF sensor will turn on the Check Engine light.
Another thing might be to remove the IAC, idle air control, also on the throttle body. See if it's stopped up with black, wet soot.
