Alright,so recently cleaned my SC400's IACV to fix a hesitation issue & when it was cleaned,it idled @1500-1800rpm & I know it takes a few drives to make the ECU relearn everything. Well after a few drives,it went back to normal & drove like a dream. But over the weekend,the 1500-1800rpm idle has came back & when in gear,it accelerates on its own. I have no idea what has caused this to come back,maybe the IACV has went bad altogether? If anyone know whats causing this issue,please lmk. Thanks!!

Pull the efi fuse under the hood and let the computer itself reset. try that if not already and report back.

This just happened to me. I cleaned and it wouldnt go away. You have to tweak the tps and the idle stop screw under the trac control plastic cover. It took me a week, trying different combos and then it finally stopped accelerating for me. Make sure you always tweak the tps AND the idle stop screw, not just one or the other. And when it finally stops, never mess with the tps or scrww again because if you do, it will come back, trust me I know lol. Once its fixed, just leave it at that

When you tilt them, just do it a tiny bit. Its also best to just leave the trac cover off so its easy access to change them. I changed them maybe 8 times in a week til it was settled.

Alright,removed the EFI fuse & reset the ECU,the EFI fuse being gone wouldn't start & it ran just the same when I reset the ECU. I've been adjusting the TPS & idle screw,made the idle issue less of a problem,but the acceleration problem is still there. Going to keep adjusting to see if I can get it to normal idle eventually lol.
