i just bought a da integra, its got a jdm b18b in it, and the idle keeps reving up and down after i start it and after i drive it up to about 5k rpm it just revs up to about 1.5k rpm then dies. i thought it was a tps but the guys at pep boys and auto zone say it doesnt have one. could it be the iacv?

 

Well its definititely got a tps... but i dont think thats it. cleaning your iacv would be the first place id start. Sorry i cant be more help.

 

Clean the iacv because its the easiest to diagnose. If not, check out your distributor and main fuel realy.
