So after I let my car warm up I was sitting at the light and my rpms went to 1300 from 750. So I'm like ok maybe I hit the gas?? Then pulling up to my house it did it again!!! I did noticed it started doing it when I pressed the clutch Pedal in. Maybe need a tune?? Btw cars never been tuned I think...

 

Ttp

 

My Evo has done that a few times. Never really looked into it as my car does some other strange things.

 

do you have the heat on? my car does this a lot when i have my heat on for some reason

 

Heat was on and how do u check for leaks?

 

vaccum leak test, boost leak test, 1st thing while your car is off, check all your vaccum lines, and do the same while its running. check behind your intake mani especially. when my car was tuned in the begining it was fine but if i turned on my AC, the rpms would rev up and down and up and down over and over, WHY? i could only assume it had to do with the car being tuned with out the AC on obviously. And besides if that was the only thing that happened that great, especially if you have mods with no tune, just remember the more **** you have done to your car the more things can go wrong.

 

get a tune

 

lol that helps alot.....

did the car ever do it before? mine will idle up and down depending on what i have turned on...a/c,heater stereo so on and so forth its just the e-fans kicking on and off...(well on mine anyways)

 

Never did it before
