car is running like $h*t!! stutering? misfire?????

on wednesday morning my car started stutering..... the night before was just fine.....it shakes and stuters in all gears and at all rpms.... but it shakes even more at lower rpms...power is obviously missing...i dont know what it is...its like if there is something holding it back...this is also a continuous stuter...i thought it was a misfire but im not sure what it is.. .. i cleaned my maf, throttle body, checked my wires, dist. cap, coil....can anybody help

could a plug have gotten loose and is wiggling around? Something messed up in the dist.? coil bad? dynamod mod. doing something it shouldn't? Eat a lot of taco's last night?
I would check with the module first, see if that's it.

i tried everything everything you stated 94blue but no change

18* timing might be a bit much. What kind of gas are you running? Probably has nothing to do with it, but just something that caught my eye.

Mine has been doing this a lot lately what module were you talking about 94blue302GT, are you talking about the tfi thingy, or what. I have also cleaned everything all plugs wires cap rotor pcv everything is new pretty much


just wondering

could be your harmonic balancer.

i agree. if the whole car is shaking..violently, to the point its undrivable..more than likey your balancer's gone out... if you got the tools its a driveway job. i had to tow mine. it fought me like all get out pullin it on the tow rig..

whatever you do...don't drive it!!!! jus movin mine took out my water pump...

It would be good to check the resistence in the COIL WIRE itself. Sometimes that slows everything down. I recently fixed a prob with the harmonic balancer in my car but the problem sounds a little different, worse.

If it's strickly low speeds it could be a vacuum leak.

harmonic balancer was changed 3 weeks ago....so i doubt its that...it just happened over night....you can also hear it through the exhaust...sounds like a machine gun or somehting

A miss or stutter can be caused by many things. When my car had these exact problems you're describing, I tried all the mentioned above and nothing. I then looked inside my distributor and the PIP sensor(I think it's called) or stator was all chewed up. There was all kinds of metal shaving @ the bottom.
Just something else to check into.

Both my cars did that last year and I changed everything ignition related out to new parts, coil, plugs, wires, cap and rotor. Still no change after all that, ended up being the distributor was bad in both cars.

The ACT sensor could also be your problem. It fixed some of mine.

my rotor in my distributor is kind of burnt on the edge..... just for info im running a cap and rotor from performance distributors

i had a problem similar to this and it turned out that my maf was the problem. it didnt go bad but i had forgot to connect it back into the hose that goes to the throttle body. so it was still sending a bunch of unmetered air into the engine.
