In the middle of traffic today on the way to work we came to a dead stop and my car just out of no where started to shake and studder like crazy. I didn't notice my tachometer doing anything sparatic so I don't think it was my idle? It was very noticeable almost like having some really aggressive cams....as soon as traffic started moving again it went away. Has this ever happened to anyone before?

 

sounds scary.

 

you sure there wasnt a 1000hp big block camaro next to you waiting for traffic?

 

I have no idea but for the sake of conversation... Bad gas, misfire of some kind, detonation, or just the beast inside rearing its ugly little head... lol

 

I hope it is nothing serious. Please keep us informed of this.

 

my SS did this but I found out something was blocking my CAI from getting air so it got pissed off until I took off again. Found out it was a plastic grocery bag

 

Wow, how did a grocery bag get up under that? Don't keep plastic bags around babies, including Cobalts.

 

No Cel? Get it checked out and let us now the results.

 

Totally off topic but where is your stage 2 report. I can't find it.

 

I kinda have that too. Like I can feel the car idling heavily through the gas pedal. Never used to happen. My check engine light came on yesterday too. The idles are normal, the temperture is normal, and the oil was just changed. 93 every time. Rediculous.

 

My dealership is telling me I need an intake gasket so im waiting after that.. Another 5 days.

 

happened to my truck.. you han't had cooling problems have you? when my truck did it it was only running of 5 cylinders... burnt valve

 

Ended up being a foreshadow into my other problem (which is in another post below). It was the boost bypass mod that caused the engine to go into limp mode...well as far as i can tell at least. I put the line back into stock location and everything started running perfect.

 

glad to hear

 

I had that problem i took back to the dealership and they had to replace a butt load of sensors.... cause they all were bad..... and i was like "HOW COULD THEY BE BAD THIS IS A BRAND NEW CAR" anyways though she doesnt shudder and shake anymore unless i have my audio system on high ... and thank the world that i didnt have to pay for the repairs... warrenty works sometimes i guess ^^
