Varying performance?

[dbartoschek]

Hey......my Bonneville has been weird on my lately....well first of all i got real pissed when i went to the drive-in and my passenger window wouldn't go back up...grrrrr....that was a nice repair bill.......anyways...i've been noticing that my car has been varying in performance lately....some days i start it up and it just flys...ready to kill anybody at the next light....and other days it struggles to even lay down any rubber, and has very bad acceleration...what could be wrong...the day my power window broke...it was having horrible acceleration...my buddies Z-24 gave me a run for my money, but i still came out on top...normally i'd leave him far far behind...i told him my car is having really bad performance sometimes...but he thinks i'm just making excuses..what could the problem be?

You may want to think about a tune-up! Spark plugs, wires, fuel filter, distributor cap, rotor, change the oil.

yah, check your coil too, if correded you will have to -LIGHTLY- sand down the connectors. Check for water damage on anything. Look at everything and check it all.

Especally what erricer said.
