Misfire cylinder 3

my dads impreza l wagon is a 95 or 96 with the 2.2l and automatic tranny it has about 200,000 (midlife) and his check engien just came on. rant eh code and it says its misfiring on cylinder three. we are gonna try new plug wires, plugs. he says the exhuast smells like gas. any idea of what it could be. (hoping nothing major ie cam shaft, rod, piston ect...)

 

The least you can do is to get a good tune-up. If it persists, then start playing with hardware such as the ignition pack and spark plug wires.

 

what do ya know, the zahn's subie problem was on cylinder 3, huh, your dad's been checking the oil hasn't he? j/k, I bet you'd get some other codes with a broken cam!

 

car runs fine, it just thros the code. the car hasnt had 27,000 miles w/out an oil change like zahns. it is probably overdue but only by like 500 miles or so

 

why aviod bosch platinums? i think thats whats in there right now

 

get the NGK iridium, for long last plugs

 

I have the cyl 3 misfire code too. Bloomington sent the ECU out to be reflashed and it came back. APparently there is no real problem and this is documented in multiple WRXs. I dont think this is your problem though, I think it has something to do with Cyl 3 being so close to the turbo. Just chiming in =)

 

take your own advice
thats why I said "I dont think this is your problem though..."

 

sorry i havent updated this. been busy. well my dad tried to change the plugs. and well we couldnt ge them to come out. the seemed to have siezed into the block. his assumption was that the plugs are steel and the block is aluminum so with 200,000miles they may be 1 piece. we are guessing that they are the original plugs. we are gonna bring it to a shop and have them take the plugs out

PB BLASTER 4 teh win!!!11 :mrgreen: That stuff is great but any penetrating lube works wonders if you let it setup and work.

My wife's old Legacy was the same way. Coming back from Iowa I could feel a funny missfire up hills. Next day it was horrible... barely could get going. Did the first tune up since owning it really; plugs, wires, oil, PCV, air filter. The plugs were so rusted and fused to the heads. Thought for sure one was going to bust apart or disinegrate the threads in the head. Soaked it with some penetrating lube and took it easy on them. Came right out.

They were the cheap'ass Champion plugs. I buy cheap'ss NGK plugs.
