I downloaded it. Can't open

Orange wire behind battey just disconnect it, engine off of course

What orange wire. I don't see any orange

 

[T What?]

There is an orange wire that runs along the passenger engine bay going to the battery. It has a plug about a foot and a half from the battery, unplug it there with the car turned off. Wait 10 seconds, start the car and let it idle for a while, it will learn after a minute or two. I let mine idle about 5 mins then went for a test drive. If you dont have an orange wire, the previous owner may have wrapped it or painted it black. If you still don't see it, take a pic of your engine bay in that area and post it. We will point it out. I started mine without doing this and it was idling crazy. So I would say that there is a strong possibility this is the issue.

Yeah I just found it thank you. I just tried this and still has a high idle. No vaccum leaks and the tps and IAC valve are good so I don't know what else to do

Do u have a scanmaster?

 

[buickGN3:16]

Have u changed plugs & 02 sensor lately?

 

[85t-typebuick]

Do u have a scanmaster?

No I don't have a scanmaster. I plan on buying one. And I changed the plugs and wires and all the vaccum lines like 500miles ago

 

[buickGN3:16]

Ok how about 02 sensor? When mine needs replacing my car runs like sh~*

No I haven't replaced that yet. I think its the only one I didnt

hmmmm never had an 02 sensor cause a high idle - just a choppy/cammed like idle. An actual scan tool would be nice (IE direct scan, turbo link, or powerclogger) but a scanmaster is better than shooting in the dark thats for sure... Do you have a way to verify TPS and IAC are 100%? If that didnt work to reset the ECM, theres always goin down to the ECM itself and unplugging the 2 main harnesses there, counting to 10, then plugging it back in.

I would hope there good. I bought the IAC and tps valve and sensor new lol. And the ecm is in the passenger kicker panel right?

 

[Homie_Telefrag]

Correct. Thats good - new parts never hurt - much How did you adjust the TPS sensor - voltmeter or....?

I took it to my buddy's shop and put it on a scanner. I forget what exactly it was set for but I looked it up what it was suppose to be

 

[85t-typebuick]

I'm gonna try and get it over there this weekend

 

[alliedmike]

hi, i am having the same issues high idle but im also randomly stalling after accell ...the car is hard to start at that point if i give it gas it will fire up... i have the maf gen 2 3 inch maf i am not sure what the settings in the maf exactly do i read the insinstructions and set it up the best way i could figure...played with some settings got the car better but still not right smells rich also....the car is a complete resto and been having issues getting it perfect since it all went back together...its an 86 engine with precision turbo stretch stock location intercooler...any information on a good starting point for these settings would be much appreciated

Here is an excellent site, and check out the "HOW TO" which shows how to make adjustment on the TPS and IAC

I think the problem is solved. Some what. It has a high idle the first time I start it and I leave it runs for like ten minutes and then shut it off then back on the idle is fine
