I seem to have a running problem with my zc motor in my crx. It feels like its not geting enough fuel even though it is. It starts fine, idles fine but when i go to put it in gear and go, it bogs out and i have no mechanical power. I checked the injector relay, fuel pump is working fine, but I can't seem to find the problem. Anyone know what this could be?

tune up

check these things out

-timing..
-any vacuum leaks at all..

and 2 questions, what ecu are you running, and is it dohc zc? or sohc?

imported_crx__4u2nv

its a DOHC and its an si ecu

Ya it sounds like you need to adjust timing, ive seen that boggin problem on 2 cars and all they need was the timing set properly. Using a timing light and a jumper wire in the 2 wire diagnostic plug.

pm7 (ZC ecu) runs the motor much stronger than a Pm6..

Like night and day when we swapped it into my bro's crx..

pg7 ecu will do the same thing with no speed limiter like the pm7 ecu has.

Funny im having a simalar problems in my ef hatch with the ZC, but it only does it when the engine is warming up, after its warmed up its fine. I figured it was probably timing.

i have the same problem but mine does it randomly

Crx7

Pg7 ecu will pull alot more but your engine will run rich as hell. Then u might have to get performance ingectors, and change your o2 sensor. Im not sure if your car will pass emmissions though b/c it idles at 1200 to 1500 rpm's

whats the pg7 out of? and my car is running now and i can drive it BUT it seems to be hard on starting from a stop it takes a couple of secs to even get it to 2200 rpms then it will start but it seems to rev high but then go no where until it hits about 4500 then it will pull what the hell is wrong??

ask on theZCR.com..

those guys deal with only zc's and 90% of em are in crxs..
