1998 Buick Century Bucks Under Load

[quote:d4f8724cd5="goodolbuick"]Buick Centry 98. about 12000 + miles Car runs fine, smooth etc. Check engine light always on, but doesn't seem to be a problem....for years.

Now, car almost acts as if it'sa transmission problem as it bucks going up hills and upon exceleration, not bad bucking, but almost as if it's having trouble shifting to next gear.

Drive it slow or moderate...no problem. Only when putting some sort of load on the engine.

changed all 6 spark plugs, changed trans filter and fluid. changed oil filter and fluid, was running hot, made sure radiator is up to par also.

Had a cracked head 5 years ago, had it re machined and didn't seem to have a problem until about a week ago...still hesitating/bucking.[/quote:d4f8724cd5]

Hey goodolbuick,
Sounds like it may be an ignition wire failing.

Chris

thank you! I'm a girl so this may sound dumb. how many "ignition wires" are there? Is it hard to change? Can it be changed? Does this mean my car is dying?

LOL You don't sound dumb!!! Should be 6 of them, and you had to pull one end off to do the spark plugs. Change them one at a time and you should have no problems. Nope, your car is not dying, just needs a little TLC!!

Thank you! thank you! THank you! :wink:

Linda,
Sure thing, drop me a line!

Chris

I agree, it sounds like you have a spark plug wire problem. ignition coils on these also are a common failure, they get rusty where the plug wire connect to them. :wink:

is it running hot as a current problem? intake gaskets are a common failure on these, also ..........may be time for another thermostat after 5 years. :wink:
