Hello;
Well this is my problem. A cylinder is misfiring; at first I thought it was an injector since it was getting a good spark from the dizzy and I had brand new spark plug put in. It was weird cuz at times it would run fine; then at a stop light it would bog out bad.

To figure out if it really was an injector I swap them all around. I placed the bad one (which was really working fine) into another cylinder and so forth, if the injector was bad then it would cause the cylinder to misfire. Well after swaping the injectors around; I still had cylinder 4 misfireing; even with a different injector.

I unplug the wire from the injector and no sign of the motor dieing out (cylinder 4). I would unplug the other wires from the other injectors and the motor would begine to die out. At this point I know it had to be something electrical; I swap out dizzy; swap around injectors; replace spark plug; and still cylinder 4 shows no signs of life.

To find out if it was the wires (brown&yellow) of the plug that plugs into injector; I swiched the wires of cylinder 3&4; guess what? Cylinder 4 starts to work and cyl. 3 dies out. I have a freaking short in that wire somewhere, causing it to work fine one sec. and then cut off another sec.

Questions:

1) Is their a big chance that the short is located not to far from the plug? I really dont feel like opening my whole harness for those two wires.

2) Their isn't really another way to change that besides cutting the wire/plug and swapping it out with another, huh?

FYI: Stock B18C1

Thanks in advance!

 

Check your cap and rotor to make sure a piece has not broken or wore away. Depending on your set take a look at your crank angle position sensor. If teeth are broken it can cause misfires.

 

theirs no ground wire for those wires, correct? (wires that plug into the injector)

 

injectors wires have no polarity so it wont matter
Injector #1 (brown) is wired to pin A1 on ECU.
Injector #2 (red) on A3.
Injector #3 (blue) on A5.
Injector #4 (yellow) on A2.
check also your ecu pins which for sometimes or some reasons dont get conections

 

thanks!
