This sounds like my problem the fast idle lever does not adjust anything upon start up. I disconnected it from the fast idle control Device and moved it by hand while it was running and there was no change. Is it possible it stuck in the open position inside the throttle body.

I think my fast idle cam (I believe that's what it's called it the device with the 2 coolant hoses going to it) needs to be replaced I also think that whatever lever that is pushes on that is connected to the throttle body is stuck open. My reason for thinking this is I took the fast idle cam off the throttle body and that lever fell then started the engine and grabbed the lever and moved it as far as it would go each way and there was no adjustment in engine rpm

I plan on checking codes today. I've pulled the throttle body and looking at it from the bottom there is a post that sticks out it looks like the butterfly valve should rest on it but my throttle doesn't close that far. Even closed to its farthest point it's still open a decent amount. I will try to take pictures and post tonight. I'm not sure how much the throttle should be open at idle if any

no cruise control but ill check injectors tomorrow. i re wired the tps correctly today and still have the same problem. it also only revs to about 4500 then start sputtering and when the engine is under load it has no throttle response. is this possibly a timing problem? i have new plugs and wires coming in the mail next week.

it has the high idle from the beginning when I bought it. I drove 4 hours to get it and got a great deal and thought it would be a simple fix. the previous owner said that the first time it ever did it was when I came to look at it. I find that hard to believe but I do believe someone has had it running and driving recently.

First I want to start with saying this is my first time posting in a forum and i apologize if i do something wrong. But to get to the point of this post i just bought a 1987 pathfinder with the 3.0 last Saturday. My problem is once it starts it shoots straight to somewhere between 3-4k and holds idle there. I've talked to a mechanic over the phone and the best he could tell me was the idle air control valve. But for the life of me i cant find any information on one for my pathfinder nor can i find a replacement for my year and engine online. Last night i decided to pull the throttle body to clean it and in the process discovered that the plug for the idle switch on the tps was not there. it just had to wires sticking out of the harness. with electrical tape on the ends. Could this be what is causing my idle problem? I know it is a problem and have ordered and new tps and plug for it so i can wire it in but if that isn't the problem i don't know what to look to next. Any help would be greatly appreciated.
