Do you really need two threads for the same problem? How are we supposed to know if you used the right spark plugs if you didn't even tell us which ones you used? What do the plugs look like when you take them out? Does it lose all power and fall on its ass or does it just have a little shimmy? Are you throwing any CEL's? What happens when you floar it?

I think you just need to take it to a shop.

sorry im new at using this. i couldnt find my old one. my bad. =[ but i did take it to a shop and they cant figure out whats wrong with it. they tested the coils the copression the ignition control module and everthing came out good. i took it to like 3 of them. they all said the same thing. the spark plug was black i took it out i had them in for like 2 months and those were the ngk i had alot of shaking with these plugs. then i went to an auto zone and ask the what plug was good for my car and they gave me champion platinum power. i put these in and at first my car was running great. but i drove it for about 15 miles and it started to shake again. but with these spark plugs the car shakes less and it picks up speed better but its still starting to shake again. and yeah if you step on the gas and the car is shaking it will stop shaking but it wount pick up speed. or the rpm will go up slowly then out of nowere it ill pick up speed fast but will stall to stall again. it will do it over and over.

i check't for a boost leak and i dont seem to have one. well the mechanic did. he said it was no boos leak. he said to check the spark plugs an i changed them. and it stopt the shaking at low rpms but when it got to high rpms the car would stop picking up speed as fast. and the more i stept on the gas the more the shaking was coming back. when i chainged them i tight them really tight and i gapt them at .032 could that be the problem? am i not changing them right?

don't even tell the auto stores what car you have; that was your first mistake.

NGK BPR6ES or 7ES if you have a good bit of modding done.

.032?

Gap them down.

ok ill gap them at .028 c if it works.no its not under fool boost but sometimes when the car stays on it neutral for a long time the car does start to throw a lil of a blue brownish smoke. it only happens if you park it and leave it on for a long time though. but what i do notice alot is that when i step o the gas i get this nasty smell and i pull over to check were is coming from and its from the spark plugs. i dont know what in the world is wrong with the car the mechanics cant even figure it out they always tell me to check my plugs. im thinking about saleing the car. i cant figure out whats wrong with it. :uhoh:

I didn't see if you finally got proper plugs. Please answer that simple question.

Blue smoke sitting for a while? Sounds a lot like valve stem seals.

Smell from the plugs? What kind?

When you "tightened down" the plugs (of an unknown type) did you overtighten them? Could easily crack the VC, plug wells, etc.

Have you done any research on the high-traffic sites? Nothing you're describing is remotely "sell the car" territory, just "find a mechanic worth his salt or DIY" worthy.

the plugs were champion platinum. i had ngk on before these ones but i had a lot of shaking with these ones . but the smell is like ruber or plastic burning.

Get rid of them. Throw them through the window of the store that sold them to you.

Look, I'm going to be honest with you...you are half-assing this thread, so there isn't much doubt you're half-assing the car.

I'm done replying until you provide concise, complete, coherent answers to the questions asked of you. If you can't take the time to research things on your own (ex. Champion plugs NEVER, EVER go in a DSM), and formulate coherent posts, I don't have the time to reply with insight in a clear format.

Sorry.

Wow... you still didn't change the plugs after TWO threads of people telling you to change the plugs. I don't care that the store said to use some Platinums or whatever, change them to the right plugs as we've told you numerous times across both threads. So before you post here again, buy the recommended plugs and make sure they're gaped properly and THEN come back and let us know what happens.

Can you imagine the nature of my repsonse had I seen/recalled the other thread?? :evillol:

People wonder why I don't go to DSM meets anymore...

I've gotta agree with lando on this one. This should have been step one to solving the problem. Get back to us AFTER you have changed these from those awful platinum plugs.
