my POS car (see sig) revs up and down when my gas peddle is held steadily. what would cause my car to do that? sensors? i replaced ecu with known-good one but did the same. im a nissan mechanic and my obd reader doesnt read honda codes. please help me out. ive unplugged each sensor and drove it one at a time but kept doing it every time. im about to blow it up.

 

vaccum leak.

 

vacuum leak? ive checked that but ill check again. anybody else?

 

is the check engine light (CEL) on? if it is it's VERY EASY to check the codes. if there aren't any codes, it might possibly be a vacuum leak.

 

I'd call an exorcist.

maybe you jumped the wrong plug? or maybe the wire you used didn't make a solid connection?

 

Search for pictures of the plug, and how to do it. There are pictorials on here - it will work if done correctly. Sounds like a vacuum leak for sure. Any recent intake manifold, intake, or throttle body changes?

 

vacuum leak was my 1st guess. your TPS might be jacked, have that checked out.
search "idle surge"

 

my fault u already did it i dind't read the hwole post and are u sure the paper clips are in correctly and u did it to the brown n black plug?

 

tow it to Tanner honda dealer in Brainerd and have them run a check for codes.
