I just did a gsr swap in my civic and its been running for a few weeks now, I got am having a little power loss though i got the knock sensor hooked up Im not sure about the IAB (intake air bypass) sensor if thats hooked up or not but my IAT (intake air temperature) sensor was either broken or i dont know the plug wouldnt stay on the sensor itself so i caucked it a little so it would stay I was getting a TPS (throttle position sensor) code on my check engine so i replaced that whole sensor and all the codes went away but when i drop it down all the motor seems to do is backfire like some sort of studder in the throttle, it goes but it doesnt have any power really, Im thinking its one of those sensors being IAB not hooked up or IAT would anyone have any ideas

Also, theres a some sort of scraping sound coming from my engine when it deRevs like when the RPMs go down its like a metal scraping sound and thats coming from under my valve cover somewhere, i just got a valve adjustment and that took care of some ticking but it still makes the scrape sound i dont know what that could be either

IF anyone has an idea of what my problems could be I appreciate it, thanks

 

damn that post was a bitch to read.. use punctuation next time.

have you tried a compression test to make sure you're not losing compression? i don't know what could be causing that metal grinding sound in the motor... anyone have any ideas on that one?

 

yeah im about to get a compression test done, My idle is high though would not enough compression make my idle above 1k, Someone told me that it could be coming from the clutch or flywheel but why would those make scraping sounds when I rev

well, the flywheel could possibly be making the scraping sounds since it revs with the motor but idk what it could be scraping against.. do you have any smoke coming out ur exhaust either when it's idle or when you're on it?

 

yea smoke comes out when im idle and when i throw it down more smoke comes out sometimes

 

what color smoke? white? blue? black?
