MY car used to idel fine at 750-850 rpm now it will not go down from 1500. If i put the car in gear it will start to stumble and fluctuate between 1000 and 1300 once i take it out of gear it will stay perfect at 1500 rpm. now i noticed that i can dissconect the main air hose that goes to the air supply valve and the bac and the car dosent stall out or even lower the rpm. any info will be appreciated

set the TPS maybe?

Just for the record..... You didnt put any of those cheap off the shelf wannabe colored silicone vac hoses from an auto parts store on your car did you?



If you did get rid of it. Its crap.



How does the car act when you get on and off the pedal? Does it seem to want to stay revved up or does it drop down to 1500 rpms right away?

when its cold it seems to want to stay reved up once it is warm it will go straight back down to 1500 rpm in gear it will stall like normal it wont stay at 1500 rpm like if i cruise 3rd in at 1000 rpm it will not accelerate the car to 1500 now as far as vac lines i got the regular black ones at discount auto not the colored ones

ohh and the car acts fine like right off the pedal like cruising at superlight throttel it is fine and when i get on it it is quick to responde and the car is super strong runs like a dream

If you rev it to about 3.5k does it try to stay there or does it drop to 1500?

it drops right back down

any other ideas

Disconnect your throttle cable. Im willing to bet something is binding up your throttle and the plates arent closing shut.

i checked that and my throttel cable has a little freeplay so i already ruled that one out
