97 lsc is chugging

[Lownslowlsc]

Well i am aware that the plugs more than likely need to be changed, but......
125k

When idling or just driving around at a normal rate it will act fine...Very slight almost unnoticable "stumble" but nothing to be concerned about..

When passing another car at wot it acted fine untill i was at the first stop light.(.5 mile) It then began the "chug" while waiting for the light to change. I guess it could be a misfire but have never been in a car with one...It didnt seem as though it wanted to die but i did keep it at 2k to see if it would smooth out and it didnt...Once i began to drive it was fine and didnt happen again...Parked it about 2 min later and it was acting normal as usuall..


Does it just need a tune up????

If you cant remember when the last time it had a tune up, yes it needs a tune up. Then go from there.

it's going to be in the garage for the winter very soon...I'll plan on fuel filter, clean maf and plugs ...If that doesnt fix it i'll dig alittle deeper i guess..

The only thing i've done so far is seafoam and i got nothing compared to my marquis...

IAC (idle air control) valve - easy 5 min replacement - cured my 'chugging' which only happened after hard acceleration, when temp not up to normal operating range, then coming to a stop.

Still need a tune up at 125K - the longer you wait the harder it may be to get the plugs out.

problem fixed yet or did you get the price on those plug wires and said i can live with it
