    Opinion needed on a guttless 99 3.8, lack of power again!!!

    I checked everything sooooo many times, every plug, wire, sensor, vacuum hose, wires, coil pack, etc,,,. I know the engine area pretty well now though! I decided to remove the Harmonic Balancer just to rule it out as a timing issue. It was cracked right down the key slot and the woodruff key...

    In gear car revs to 1300rpm fine then after a few seconds start to sputter

    If it runs fine when cold, worse when hot, could be the MAF or IAT sensor. The IAT signals the intake temp prior to the MAF and controls the percentage of air to fuel. If the engine is hot, and you are using an air filter (like K&N), which is taking air from the hot engine area, or if the sensor...

    In gear car revs to 1300rpm fine then after a few seconds start to sputter

    My 99 3.8L Stang, and my Kia, both needed new MAF's in the past year. One in the stang just quit, started dumping way too much fuel, ran terrible, and the kia MAF, after taking a closer look, had a missing piece of 'foil' on the air flow sensor (which is also incorperated into the MAF). That's 3...

    In gear car revs to 1300rpm fine then after a few seconds start to sputter

    I had issues with my wife's car as well, and though you probably checked this already, I'll mention it anyhow. I had a mechanic at my place today, working on an impala, which had about the same issues. Revs fine with no load, but put it in gear (load), try to rev it, and it runs rough, sputters...

    Opinion needed on a guttless 99 3.8, lack of power again!!!

    I had a similar 'lack of power, sputtering, slight popping' problem last year on my 99 3.8. I changed the fuel filter, pump, cleaned the MAF, routed the PCV valves together (thinking that may be an issue because I never seen a set-up like that before), checked plugs, coil packs, wires,,,, then I...

    What do you do when someone makes fun of your V6?

    I have a v-6 also, 5 speed, looks great as far as I'm concerned, and I like it. Who cares what others think about a car or anything else that you're fine with. Belittling jealousy from a person that you haven't offended in any way, is just a character flaw, insecurity, lack of self esteem...

    Vibration, still looking for the cure.

    I had the same issue years ago, was the vibration damper. You can try looking at the rubber center, seen more clearly from the back. I wasn't able to notice any difference just by looking down at it from the radiator side, but from the backside at the bottom it would be visible. Does it appear...

    Slow accleration, moderate jerking, noises

    I assume they cleaned the fuel tank and replaced the filter,,,, at least that's what I thought when I brought mine in for the exact same thing. I had acceleration issues, knocking, jerking, all the same issues as you mention just a few days after getting it back from the garage. I did a rail...
