i have a 2002 v6 with 56000 miles. First owner and always kept up and the basics, oil change, filter changes, etc. Recently i had to have the battery replaced. Since then I have had a strange shake and shimmy. I feel it when I am at a stop light or parked. It died on me once and ended up changing the fuel pump. The shake is still there. I have replaced the fuel filter, air filter, oil, plugs, wires, and cleaned out the throttle body. Shake is still there. My muffler had a hole on the bottom and I had that replaced. Shake is still there. What in the world could be wrong???

Re: Strange shake
Does it's a little shake? My car do this at idle but i think it's normal. -
Re: Strange shake
not that little shake........I am OK with that one. Its the BIG "push" and then little "after shocks" that i feel. Feels like a misfire, but no codes or SES lights. Vac leak ?? vapor lock ?? air in the cooling ???
or could it be the fact that I sent my last payment on the car ???Comment

Re: Strange shake
my brother's car would "pulse" whenever it was at idle and it kind of shook a little bit. I see you replaced plugs and wires but have you replaced your coil packs? thats what was wrong with my bros car.Originally posted by vegaluvComment

Re: Strange shake
I was gonna say the same thing. There's a good chance that it's the coils. The 3.8 cars have three coil packs. One pack controls two clinders. If one pack dies, it's going to affect both. Anyways, coil packs are generally pretty cheap, I got mine for around $35-$40. Just buy one, and change out one at a time. If your shaking and stumbling is still there, put the old pack back on, and replace one of the others with the new one. Once you have checked all three packs against the new one you'll either have cured the problem, or found out that it wasn't the coils at all. If you end up with the 2nd option, take the coil pack back, orrrr buy two more (replacing all 3, your choice).Originally posted by tkoforpresident
Another thing that could be happening is the ICM is dying. The Ignition Control Module is supposedly the box that the coils mount on, controlling the spark that all 3 coils receive/distribute. They can be pretty expensive.
One other veryyyyy slim possibility is the PCM. My buddy had a problem with his '01 T/A WS6. He was getting missfires and the car would just die randomly on him. Sometimes it wouldn't start. It wasn't because of the VATS PassKeyII or anything, his security light was never on. It just wouldn't start. He replaced the PCM and the problem was gone. He decided to try the PCM after some people on LS1Tech had told him about their similar problems with the non-start, the dying while driving, and the misfire.
Hopefully you won't have that problem though. Hopefully it's just a coil pack.~Chris<br />1999 Hugger Orange Camaro<br /> <a href=\"http://www.cardomain.com/ride/273836\" target=\"_blank\">http://www.cardomain.com/ride/273836</a> <br /><br />†…faith…hopeComment
