when the motor is running and the belt isnt sqealing i can hear everything clear and i hear a whistle coming from the back of the motor and i sprayed brake clean on the hoses and when i sprayed it on the pcv valve the motor started choking more. pulled it off checked it out its good its actually a few months old (nov. 2008) i hooked it back up sprayed around a little more and around the IACV it choked again. i unplugged the MAF and it ran better but once i tried to give it fuel it wouldnt pass like 2k-3k rpms without bogging. i did a search on here found nothing. i did a search on google and found this had happend with a nissan pick up and it was the maf but i dont think its my maf. this problem occured RIGHT AFTER I DID THE INJECTOR ON CYLINDER 5... thanks in advance!

 

Did you have the MAF and IAT unplugged with the key turned to ignition?

If so, that's why you have the codes.

Have you narrowed it down to the IACV?

 

i accidently forgot to plug in the maf and air temp wires when i started it. and it ran but wouldnt rev up so i rememberd and quickly shut it off and plugged them back in and it ran fine and today it started acting up and i checked codes it was the codes posted up. i erased them and havent checked it again since. but its still having a rough idle and sometimes about 90% of the time now a stalling issue

 

reset codes. no CEL but checked it reguardless same codes came up, car still runs like doooookie.. i can hear a leak somewhere.. it whistles loud but i cant find the leak!!!!! cant seem to find a hose/wire diagram for the intake manifold/throttle body section of the car in detail or good enough info/pics..

 

Are you Cali or Fed spec?

And to find a vacuum leak, get some smoke going, or some brake parts cleaner/carb cleaner/starting fluid.

 

no idea what spec i am? how do you tell. and what do you mean smoke? i know if you spray the fluid on hoses youll hear a change in the sound of the car.. but when im spraying its changing a little bit but the hoses are all hooked up to something and look like there where they belong..

 

In the FAQs...

Smoke as in...smoke. Cigarette smoke, a smoke machine, whichever.

 

it is a U so not Cali... i understand what you mean by smoke, but what do i do run it threw another vaccum line? and see where its coming out?

 

No, you smoke up the engine bay, and see if it's being sucked into the engine anywhere. That'll show you any vacuum leaks.

 

i can do that.. but it wont help me find out if i have any crossed hoses.. thats why im in search of a diagram
