My 2001 Buick Century Custom (3100 engine) surges. It feels like a firing problem in that it is bogging down as if it is miss firing then returns to normal. We have recently put a gas filter on it so I don't think it is the gas filter stopping up. Any suggestions as to what may be causing this problem...Thanks.
NOTE: I'll be happy to adjust the donation when someone can help me out as I didn't know how much to donate to be fair...Thanks again.

I would check fuel pressure,should be 52-59psi and also check the spark plug wires at the ignition coils,they burn and get rusty real easy,very common.it both could cause a missfire.post back with what you find.

It appears the problem was coming from a spark plug wire not connected well at the coil. Thanks for your help.
