Hi i been having this problem for a little over a month now. the car starts and runs but it gives a misfire in all cylinder CEL and only three cylinder would run. i change the spark plugs, spark plug wires, distributor cap and rotors, injectors, and thermostat. At first it would just burn oil and i was loosing coolant and car was over heating but never had any whitish blue smoke come out. then later i get this problem. could it be a head gasket because that what i am thinking of doing this week end and also check to see if my rings are out. but i was wondering if there some other causes. I think that it could be fuel related since it starts fine and all the wires give spark. I dont think its my rail since it happens to only one cylinder ( its the second to the left) i think it might be a wiring problem but dont know where to start with that. My brother said that my timing might of jump and i am just at a lost so i came her to ask the HT professional and see what they think.

 

also if this helps when i pull out the spark plug for this cylinder nothin happens. when i unplug the injector connector for this cylinder nothing happens.

 

You might get a shop to do a "leak down" test on the possibly dead cylinder. The simpler test (compression test) is one you could try just to see if the piston is moving at all in the cylinder. From the coolant loss and everything you described, if you get a pressure reading at all on that cylinder it will probably be very low compared to the cylinders that are firing.

 

Are you getting spark to that dead cyclinder? which injector with another cyclinder?
is the spark plug soak in fuel?

 

im getting spark for sure spark plug has alot of whitish stuff (on the cylinder that not working) on it after new ones were install within a week. i bought brand new injectors for all four. i think it might be a dead cylinder what would cause that and how would you fix it. I was already planing on rebuilding the motor with new rings and pistons but that was my plan later for next summer

 

If you take a closer look at the spark plug and it's actually the color of your coolant and appears to be crystalized then it's probably a coolant leak into that cylinder.

 

ok well right now i will be replacing a head gasket as long as i can find my dam tools. so **** buddys will come over and take tools when im at work and when i try to use them they all missing.

 

Odds are that your head is warped. Make sure it's straightened and resurfaced by a reputable machine shop.

 

i do have a h22 head that already in the machine shop that should be done within a week

 

but i dont really want to put that on until i get every else ready for the car.

 

so right now i couldnt get started on taking off the head by the time i got home from purchasing a nice ratchet it was to dark and cold dam mn weather

 

I'm going to guess it has a burnt valve. That could be easily verified with a leakdown test.

 

the head was fine fixed it yesterday. it was the head gasket. we put it on and did an oil change and it fixed it.
