funky idle...


Recommended Posts

Well, i just got my car, and i've noticed that the thing idles like crap. Generaly that indicated worn iginition part, but all of mine have been replaced or are in good shape. The car's idle sitting in park, neutral, whatever bounces around from 600- to 1200. It shakes enough to make the hula doll on my dash go nuts.

 

I have another problem that when driving my car will hit a certint speed, and the car starts to rhythmicly vibrate, like a bulge in the same place of all four tires, happens at 45 and 75mph.

 

Any suggestions any body?

see subject line

My suggestion is to list the

1) year

2) engine type

3) fuel system employed

Sure sounds like a bad IAC but it could be EGR related also.

Possibly knackered vacuum fitting or even ....

 

 

The wobble could be a broken belt in a tyre, or a poorly balanced tyre (lost a wheel weight possibly)

tryin' ta help but the Great Carnac I'm not (whew that's showin my age, "The answer is....")
