I am doing an EG Type R hatch for HPDE course work and am in the process of getting the engine to run correctly. Here is the background on this engine:

I bought it from hmotorsonline about 7 months ago. We started the engine up once it was installed and it ran great. We did some wiring on the ECU and finally got it working with Kenji's P28 (thanks Kenji). After wiring and the engine now having VTEC it felt strong (still need dyno tune though). A couple of days ago i noticed a somewhat bad idle. Like the car shakes up to 3k RPMS. I thought nothing of it so we installed Skunk 2 Stage I cams last night and started it up and the bad idle was still there. We figured it out to be the #4 cylinder not firing. We checked the plugs, wires, compression (240 across board), and the timing marks after doing the cams and cam gears.

We thought it was a bent valve but with those compression #'s it couldn't be. The only thing we can think of now is to swap injectors and see if that might be the problem. The car is not throwing an ECU code at this point. Can anyone give us any insight?

Thanks very much guys

 

i mean if it is getting spark and has compression i think your guess that it is the injector is probably accurate. did you ohm the injector out? i wish i had the spec for the resistance, if you need me to ill get it from my work, unless you have access to an alldata type program, then just look in the diag and repair section and their should be a spec section.

 

If your #4 cylinder isn't firing it should throw a code. Make sure you have spark and fuel at every cylinder. Hookup a fuel pressure guage if your can and spark test the cylinder.

I believe it should read 12 ohms, but you can check it against the rest.

 

damn bro im sorry i didnt get your pm. i just realized how to veiw them, if you still need it ill get it tomorow. im writing a note in my phone right now

 

yeah, the spec is no more than 12 ohms
