Won't Rev after Throttle Body swap

Fixed everything.. The FITV was really defected even though I clean the inside and re tightening the valve. Replaces it with my D-series FITV and it idle normal

Re: Won't Rev after Throttle Body swap

Did you set the tps correctly? Also are the plugs in the right sensor?(tps and map plugs)

When I first set the TPS wrong on my 1st swap, It gave me a code so I believe the TPS is set properly since it's not giving me any code...

My exhaust is also smoking....

Re: Won't Rev after Throttle Body swap

have you taken a multimeter to the TPS input at the ECU to check for proper voltages?

Re: Won't Rev after Throttle Body swap

Figure out the problem and vicsrex was right, I did have the TPS and the MAP flip flop.... but my CRX idles at 2000 RPM even after warm up.

Re: Won't Rev after Throttle Body swap

Yeah I'm probably going to take off the FITV off the TB and clean it... The IACV was working fine before the TB swap so I doubt it's bad. I might even check the TPS setting again...

Re: Won't Rev after Throttle Body swap

The voltage on tps should be 0.5 at closed and 4.5-5 open. Like EFkid said check the throttle cable, also vacuum leaks and idle mixture screw

Re: Won't Rev after Throttle Body swap

The TPS was fine but I found out that the FITV was defective. Had the motor idle at 2000 RPM and once it warmed up, it started to surge at 1000-2000 RPM. Put my finger on the lower FITV hole inside the TB and it had strong suction. Also, when i had my finger on the hole the idle went down to normal, so I will replace the FITV with another one.

Yeah I actually used that link but it didn't help. My friend has an extra FITV and I also have one from a D-series so I'll switch it around...

Thanks for the help..
