I have spent so much damn time on this...IDLE PROBLEM...changed map, idle air control, and my com puter said they were bad. well constant 1-2000 rpm idle still goes. Is a pcv or tps possible? Im so ******* tired of dealing w/ this...Just did an exedy clutch but I cant enjoy it due to over frustration w/ the IDLE..I hate this ******* car right now

 

OKAY, engine light blinks 4 long, 3 short...43 right? So does a bad fule pump or filter cause a nasty constant idle? doesnt make sence to me. I really need help w/ this...It just says fuel delivery on the code page..is there more it could be in the fuel?

 

Check the throttle cable and the adjusting nut or the throttle stop screw on the TB. Is it binding? Or too loose? Sticking?

Maybe you accidentally switched the Map sensor plug with the Throttle position sensor plug. They are identical and fit each other. Worth a shot.

Or maybe you are not seeing a loose or unplugged vacuum hose somewhere on the manifold.

Get a second pair of eyes to help you out. I'd be working on a car forever trying to figure out WTF was wrong and my mom would come down, peak under the hood and say "what's that loose wire for?" or something like that. And wouldn't you know it... that was the damn problem!

Good luck!
