I replaced all of the sensors and also the TPS but now when I start the car and let it Idel it surges at idel around 4-500 RPMs at a constant speed going up then down then up then down. Any help related to this would be awesome. The engine is a Y8 Vtec.

 

Vacuum or intake air leak?

Bleed cooling system?

Adjust idle speed?

CEL codes?

 

there r 2 codes i keep getting it is that both 02 sensors have gone bad cane both go out at the same time or is there something else causing this tks for your hlp its getting on my nerves lol

 

I have seen in the past that if the first one fails, it will throw a code for the ones behind it. I don't know if this is just some times or all the time.

 

Post all codes. Then reset the ECU to see whether they repeat.

 

+1 see where that gets you. To reset codes unhook negative on your battery for 5 minutes or so.

 

ok fixed the idle problem tks a lot it was a vac leak waiting on a code reader i ordered to see whats going on now
