Can anyone help. my 2001 gt has just begun sputtering at low rpm but fine when above 2000rpm. any ideas on what the problem may be.>????

i would be the first to guess plugs, the reason you wouldent notice them at higher rpm is because your car is fireing more often making the 1 being missed harder to noticed, had the same problem recently, if your getting a check engine light take it up to auto aone and they will tell you which cill is misfireing, either way if your having problems w 1 id change them all

apparently it is misfiring on one of the cylinders how long does it take to replace all six spark plugs and should i do anything else at the same time???

Um when replacing the plugs you should prob do the wires also and its not hard to do but it does take a little time maybe an hour or two? But that is most likely the problem that ur having...

You have to remove your exhaust plenum to get to the back 3 plugs. But gmar is right, you do want to change your wires as well. It's not hard to do, but at the same time it's not easy if you don't know what you're doing.
