I read the service manual on what cause or how to fix misfire / check engine light on.

Wires are ok, changed plugs but vavles r ticking little bit. Changed one of the injectors but still did not help or solve my shitty problem. Also when i pulled out my fuel rail along with the Injectors i found some black powdery sh*t around the injector hole/well. Is that a bad sign? what are those black sh*t?

I just bought this car and the previous owner did something stupid on this. I also notice that the dizzy got adjusted cuz there's some mark on it like a scratch line.

Now, some say that OBD2 does or dizzy is not suppose to be adjusted cuz of the crankshaft sensor?

I really need help guys.. How do I put the original setting of the dizzy? Do i need to put that service check connector and adjust it? Some guy in the forum say he adjusted his dizzy but by the time he pull the service check connector it went back to same problem on his timing.

Is the misfire problem i have right now has something to do with this incorrect adjustment? Everytime I reset the ECU it comes back on ONLY when i start the engine in the morning. In other words, when engine is cold. Burns oil too, they said it's cuz of the VTEC sh*t?

NEED HELP! HELP! HELP! HELP! HELP! HELP!

 

need help pls

 

there is a way to set the ignition timing there is a wire u gotta jump. i obd1 so not sure what or were the wire is

 

Black stuff around the injectors could just be from the old grommets. Could be carbon build-up blowing back too. Ignition timing on OBD-2 is controlled by the ECU. Never needed to mess with the distributor. Where is the mark? If you are burning oil the misfire could be because you are not getting enough compression until the engine heats up and the metal expands to fill the space by the worn valves or pistion rings. Does the misfire go away when the car warms up?

 

yeah, it only happens when it's cold like early in the morning. When i had the injector replaced, that was around noon so it was pretty warm day. So I thought it fixes the damn problem cuz CEL did not come on. But once again, when i went to work 5am in the morning that CEL came on mulitple misfire.

I have low compression on cylinder 2, but i was not sure if i did it right. Lot people here says that i need to warm up the engine before i do compression test.

the mark on the dizzy is on the metal housing of the dizzy. Since the ignition timing is controlled by ECU, is that mean that i don't need to have the timing light hookup when putting the dizzy back to spec?
