what should it act like with the idle air control valve wiring harness un hooked?


i've been having an over heating problem, and a crazy idle that rev's to 2200 and back down to 1000... and back and forth...

last night i changed the thermostat... and bled the air out of the system...

it still idled crazy.... i removed the air filter intake, and when i plug off the side hole in the TB with my finger, it idles fine....


i unplugged the harness to the idle speed control valve... and the idle got a lot lower and it stopped rev'ing up and down... but it still idles at 1300....and lopes to 1400>back to 1300>1400>1300

what should it act like with this wiring harness un hooked?

 

You'd proabably have erratic idling. Have you tried adjusting your Idle Screw to see if it would go down to 700-800 RPM range?

 

yes... i have screwed it all the way in with no luck... and tried screwing it out... and it only got higher...

 

Did you just hook this engine up or did it just start doing this?

 

it just started.... actually about 3 weeks ago... after i changed plugs and
cleaned the TB with some carb adn choke cleaner...

for about 2 weeks it started idling fast.. like 2000... then about a week ago
it began the reving up to 2200, and then falling to 800-1000... and reving to 2200 and falling.... and so on...

 

well i just realized last night... that my engine light does not come on when i first start the car to let me know it is working... so i very well could be throwing a cel...

is there a way to pull the cel codes with out having the dash light operating?

I am thinking about buying another car and I don't want to get shafted by someone pulling a bulb to hide the CEL. I was just thinking about this same question the other day.

bump for my curiosity.
