I have searched the forums about my cold start problem, i came across a couple of threads and tried what it was said on the thread... i did a complete tuneup, changed temp sensor, New starter, and FPR.. But it seems like the problem is still there it only does it when the car is cold but when i drive it around the car starts up just fine. It only takes me two turnovers to have the car start. Also when i press the gas pedal it gives me a weird vibration that i have never felt before i owned this car but it runs fine should i worry about it?

Wheres the Vibration, in the steering wheel? is it an Engine Vibration, Tranny related, suspension?

If you've got a Cold start problem, and a vibration Until it warms up; The Vibration could be the Engine just running rough, and the harshness could be casued by more than a few problems. Got a CEL or SES? Any recent maintenance?

Welcome to the club

 

By tuneup, i assume u mean u have cleaned TB, and MAF. Possibly cleaned IACV (i dont think IACV is yur problem tho). AND threw some chevron techron in the fuel tank.

U check CKPS and CPS per FSM??

 

no i havent cleaned the TB or the MAF im kind of scared to clean the TB since alot of people experience high idle after TB clean MAF sensor im going to clean friday but i wouldnt think that that would be the problem...
I have no CEL and the vibration occurs when i step on the gas like 4 inches into the gas only the pedal gives me a weird vibration ,,,What could it be?

 

I am experience the gas pedal vibration also. I have been kind of floundered as to what it could be but I assumed it was normal since its been happening for so long without any major problems. But when I first start the car when its cold, I can hear a vibrating sound, kind of like the sound of a electric toothbrush and when I put my foot gently on the gas pedal without actually stepping on it, I can feel the vibrations as well.

But once the car is warm that vibrating goes away.

 

sounds about right but on mine even if the car is warm i still get the vibration its really weird but sometimes its more moderate than other times....I guess its nothing bad hopefully

 

might be worn suspension parts too. New bushings might be needed.

U can clean TB no prob. PPL who had high idle or issues afters got vacumm leaks from actually removing the TB and not using a proper gasket for reinstallation.

U dont have to remove it. Jus get some carb cleaner, a rag and a stick and clean inside as best u can. Thats what i do every few months. No issues whatsoever.

 

Thanks cashoit i will try that friday when i get payed...Im wondering how much to replace bushings in the suspension would be Pricewise. but the car works good no mods so far due to no money but high mileage, What kind of Engine oil do u recommend?
