And throttle cable can move freely through its intended range, I have not cleaned it, dunno if he did.

Just got car, from friend, started doing this after taken off the road for paint. I can take it to his shop and he will pull codes we just haven't had time ( I'm on the road). I was hopeing this may be a common enough sympome.  It does this instantly ( 3 grand idle speed) and constantly,(occationally it acts as if it sputters but is just dropping to a more normal idle maby 1 to 1.5 grand if drifting or light throtle. Heavy throtle seams normal. Uppon Shut off it runs for a few ( like 2 or 3) seconds and that is followed by a low pich wine. not like and engin "Deseiling" though, it runs smooth for those few seconds.

We had thought of that bit didnt figure it would do that much... of course Im more used to carbs...  we sprayed carb cleaner everywhere (to find a leak) but no results there, gonna try more this weekend when I get home.

yep new to here...

yep searched then got lazy after half an hour

Ok so it mostly wants to sit at 3 grand in n or p about 1.5 grand when in gear, suspect tps or that ice thing ontop of the throtlebody. I dont have much exp with the injected stuff, im used to 70's pickups.

also sometimes it will "stumble" back to normal-ish, no its not downshifting, it will do it in first gear (selected) , so the problem intermittantly goes away, verry briefly mostly at light throtle. When i let her eat she takes off normal, it just wont idle where its supposed to.

it is now giving me the "light" so i will get a calibrated paperclip to get the code which i need to find copys of.... gona try google but if any one has the list a copy would of course be welcomed. and which pins on the connector do i jump.

Thanks
