i just remembered.. it had a high idle when i bought it.

guess i didnt cause it. there is a open tiny black hose that i need to figure out.

get a picture of the block hose your talking about.

i didnt read through all 4 pages, but what comes to mind are: the throttle pos. sensor, maybe even the crank pos. sensor , i think the first page mentioned the IAC.

does it stay at a steady 2,000 or does it jump up and down?

the black hose is suppose to be lose i think. my camaro's hose is lose too. its up by the brake cylinder bottle thingie.

it stays at 2500.

there's no such thing as a vacuum hose that is supposed to be loose. that is why your car idles high.

its coming out of the clutch cylinder or whatever its called. i thought only stick shifts had it under the hood but my automatic has it too. its a 3.8. the other car has the same hose lose and it doesnt idle high. its up at the drivers side corner of the engine bay by the windshield.

the clutch master cylinder reservoir only comes on manual cars, the only way you would have one is if someone converted the car to a auto and left it there

i couldnt find a vacuum leak. is it possible the the RPM guage is incorrect? because it doesnt really sound like its idling high. but idles at 2.5. when i drive, at 70, its past the red line.


i also have a 3.8 camaro, so i swapped the sensors out to test them. like the tps and air sensor and egr. just to see if that was the problem and it still idles high. the sensors that came off of the firebird work fine on the camaro..it idles at 1.

could still be a vacuum leak that i havent found

but its definitly not the egr, tps, air sensor or pcv valve.

i also swapped the maf sensors, they both work fine on the camaro.

i belive it idled high ever since i bought it, cuz i remember i was shifting at 3... where i used to shift at 2 on any other car.

Hook a vacuum gauge up to it, that will tell you if there's a vacuum problem. The vacuum should be around 20 i think. If it's substantially lower then there's a leak.

^yes, -18 to-20 is normal range.
