Engine Tremble

[Aaron Martin 2]

I have on 02 trac with 75k on it. Lately when I am sitting at a red light the engine will kind of stutter or tremble and the RPM needle will jump a little. Any thoughts on what this is? I have a K&N air filter that is clean and I replaced the fuel filter and spark plugs a few months ago.

Make sure there is no oil on the MAF sensor from the K&N..... also see the projects... Clean the IAC motor...

And check the common elbow that cracks..



those are the BIG 3 that the St has..

If those dont solve it. We have had some members, that the soleniod realeasing the torque convertor from, 1 to 1 lockup fail at idle. It will lug the motor down.

martinaaron, I have a '03 with 65k miles and my Trac did the same thing until I had my mechanic add 44k to my tank and performed an induction cleaning. It stopped studdering at red lights.
