hey i have a 1993 3.4 and when i start it up it revs to 1500 rpm and i just wanted to know what are the common vacum leaks occur in these cars
any help would be much appreciated

 

On my initial start in the Morning, mine idles around that for a few minutes.

Is this the after driving it for a few minutes?

 

granted i have a z28 5.7, from a cold start idles at around 1000rpm till it heats up then drops down to around 600rpm.

1500 seems kind of high to me. check your IAC valve & motor, there's been a lot of this going around lately seems like. if its all carboned up simply clean it off and you should be idling normally. if not, then im not sure.

 

it happens all the time no matter how long i drive it ....there seems ti be like cracks in this rubber t on top of the engine and i cant seem to located another one

 

can u post a picture of it. i may be able to find a part number in my book.

 

yes clean the idle air control valve. its on the passenger side of the throttle body.

 

yea ill try to get a pic of it in the morning

 

is there any common areas on these cars where there could be a vacum leak

 

are u hearing a sucking noise?

 

cant really tell over the exhaust but i dont know much about these cars i really dont know where to look for possible air leaks
