i've been having this problem for awhile now.. once i shift into neutral my car will occasionaly idle up to 3-4k rpms but when i push the clutch in it'll stop and go back to 1k rpms.. well now it just idles up there till i start to go.. what could be making this happen!!

 

my car is acting the same way...#1) you have a vacuum leak (if your gauge isnt broken, what does it idle at? - should be around 20-22 vac. #2) your TPS (throttle position censor) has gone bad. (its on the bottom passenger side of the block if im not mistaken. check for any lose hoses, lines run a boost leak detector and see if youre losing any type of pressure/vacuum anywhere. do you have anything done to the car?

 

it does it sometimes not all the time.. i have a bov, manual boost controller, mopar exhaust, intake

 

it makes me mad

 

well stop whinning like a baby and get it fixed.Check you vac lines....there must be somehting loose.Also recoment to change the stock boost gauge, it'll brake eventually

 

check the wiring to the TIP sensor.

 

^^^^^ bingo

 

i think i know why mine is idling bad, but just in case where is the tip sensor wiring located....isnt it off the #3 sensor?...i guess i could check the manual, but if anyone knows off the top of the head where it starts and where it ends i would appreciate it
