I'd start looking for vacuum leaks. Or one big one. You might have to pull the intake and check the gaskets.
I’ve checked some vacuum lines and they seems fine from what I can tell. The #8 fuse was blown throwing all the codes. I replaced it and still the high idle. The weird part is that when I disconnect the battery, the high idle fixes itself for a moment but then right back to the high idle almost telling me it’s a sensor issue. Also explaining the blown fuse. Just don’t know whatI'd start looking for vacuum leaks. Or one big one. You might have to pull the intake and check the gaskets.
Nah you good, I have it running when checking for any vacuum leaks lol. I’ll have to try the cigar idea I know you can smoke test it with a kit but it’s kinda pricey. But do you think a vacuum leak could cause THAT high idle. I’ve had vacuum leaks on many other vehicles and it just causes it to idle 1500-2000Just in case engine not running when using the cigar idea for vacuum leak check … I’m not trying to insult you , I bet you knew that but there are some out there who don’t ..
Thanks! I put a new one on it a couple weeks ago. Just tried it and unplugging the IAC did bring down the idle lower to like 1000. How do you reset itIdle air control , sometimes they need resetting there’s a process on it too or it will make the car idle higher if not set or properly functioning I know this I went through it .. was a pain in the ass… if you have a decent scan tool it will show current idle Rpm’s and the (remedes) it’s the idle speed the cars pcm has set it’s usually 700-900 rpm range but may very on the vehicle. The idle air if not functioning properly will cause higher rpm like 1200-1500 rpm . And the scan tool can show the values of the idle air & if it’s not set or not functioning it can mess up the idle.. my car idled at 1250 but it threw a code for the idle air so I knew the problem. Try unplugging the idle air when running see if the idle drops to almost a stall or around 450 rpm’s it can tell you if it’s working or not .
Okay thanks!!There’s information out there on resetting the idle air id do a search or look on YouTube for it there’s a few videos out on it .. Hope this helps you I had to do quite a bit of research myself but it ended up working with my cars situation..
