ok heres the story.. i have a stock LS B18B with a stock P75 LS ECU and when im driving and i push the clutch to get out of gear or whatever the RPMS shoot up to around 2,000.. but then if i tap the gas while its at 2,000 it'll rev up like it should if u tap the gas and then fall back down to about 1,000.. and if i start driving again and im doing say 1,500RPM in 3rd and i push the clutch the will go up to around 2,000 RPM and sit there and idle there.. untill i tap the gas and then it goes back down to about 1,000 this is all while the engine is at normal operating temp. ANY IDEAS? PLEASE HELP!

i already tried resetting my ecu and no help there

 

need help ASAP because i need to know if i should be driving it or not

 

did u check to see if the idle screw is backing out of the throttle body?

 

checked and hasnt moved anymore ideas ??

 

my ls in my crx was doing that and it was the alternator going bad. Got a used one and hasn't happend since. Hopefully this might help, i'm not sure!

 

hmm

 

throttle cable sticky? enough slack in it?

take off your intake and plug the hole in the throttle body that lets air go to the IACV. any effect?

 

let me know if the distributor works!

 

CORRECTION------------i wrote alternator the first time and ment to say distributor.
IT was my distributor

 

i would look at the throttle cable as well

... throttle cable sticking or intake manifold gasket leak would be the first things i would check for

 

throttle cable is only about 4 weeks old i guess i should check Distributor and Intake Manifold gasket

 

also take off distributor cap, i've seen moisture get inside that cap. Clean it out

 

hmm tightened my loose squeeky alternator belt and it seems to idle fine now?? could this be all that was wrong?
