Idles at 4000 rpms, popng noises, engine shakes
 

When i start the car.. it idles almost to 5oo rpms, it also makes poping sounds, and the engine shakes...

Backfires?

Also, the popping might be if your muffler has burned from the inside out. Listen for them from your exhaust pipe.

check and see if something is holding your throttle plates open.. throttle cable way overtightened/binding on something/SOMETHING.. a car should NOT idle at 5000 RPM.

Maybe he meant 500 RPMS? If it's popping and shaking really bad, I'd venture to say that he could have a blown engine. I know when my engine popped, it exhibited all the symptoms that he's describing.

Here i'll be more specific....

I turn the key.. (starts), RPM gauge rises to 4 Rpm's, Then Slowly goes Down to 1Rpm's ( it takes about 1 min approx) Engine tends to Shakes every 2-6 sec. (It almost looks that its about to Stall but doesent)..

ey guys i can send you a detail Movie its just i dunno how to paste it...

The automatic revving after you turn the key is the cold emissions assist. It is very bad for your car to be revving that high when cold. To stop this from happening start the car in first gear. Not sure about the shaking though.

Mine did the same thing. Ummmm....I don't know how to say this so....for all of your engine rebuilding needs, many people recommend Don Marvel at MarvelSpeed.;)

So you want me to get the Fantastic four to rebuild my engine?? WTF ???? First of all my car is not in cold tempetures(Iv'e read an issue about that in Haynes Repair manuel). My friend told me its all the Build up in my Carberator..i think i need to clean out my fuel ijectors
