IAC Vale and Misfire problems - '00 with D15B swap I previously posted this in 5th Gen but i think it should be here. **1st post** I got this car back in October, it drove great until December. I started having problems with high idle, within the week it went from a high idle to a fluctuating idle (800-2000rpm). That weekend i checked the codes and all it said was a misfire cylinder #1, i replaced the wires, plugs, rotor and cap, and #1 injector. The problem did not go away, then is started throwing the IACV code. I cleaned the IACV, didnt help so i replaced it. --Even with a brand new Denso IACV(same as i took off the car) it is still throwing the IACV code and having the fluctuating idle. ~Is there anything special i needed to do when replacing? --With the new plugs, wires, cap and rotor,fuel filter, injector in #1 - I am still haveing the misfire problem, i have done a compression check and all cylinders are at 170. ~ Could the IACV problem be fooling the computer to thinking its a misfire? ~ Can the misfire be causing the IACV problem? ~ Maybe the valves sticking? ~Maybe the distributor? Im kinda lost at this point! ** second post ** Ok, bear with me im learning more and more abotu this car everyday. I has a '00 ECU and Intake Manofold but a D15B block with vTec, so im thinking ill repost in 6th Gen since the problems seem to be coming from the parts off the '00 Year - 2000 model - Civic trim - ? all power with sunroof #doors - 2 engine - D15B - Previous owner swaped. Still has '00 ECU/Intake trans - Manual code numbers - 14/ 71/ 72/ 73/ 74 |
Re: IAC Vale and Misfire problems - '00 with D15B swap Have you checked the TPS yet? It is one of those known causes for the symptoms you have.. |
Re: IAC Vale and Misfire problems - '00 with D15B swap i have not. i was thinking TPS but with the money already put into it I needed a second opinion, its not throwing a TPS code its throwing IACV code.?.? Looks like ill be cutting that damn thing off this weekend :_disgust: at least its only $40 |
