misfire sti 1994
Have a miss on one of my subaru's (WRX STi - 4 door GC8), which happens about 6k rpm.
My question is: should there be a washer/spacer BETWEEN the cam sensor and its mount on a GC8 4 door WRX STi? and NOT one on a 2 door version of the same car?
Tried plugs, leads, coil pack all to no avail.
Luckily I have a 2 door WRX STi Type R (GC8) sitting around (as you do
) to swap bits from to check what the problem might be.
Decided to try the cam sensor, and when I took the one off the 2 door, it had no washer between it and the mount, yet the 4 door one did.
I didnt notice this, and bolted the 2 door cam sensor into the 4 door and whirled it over, and the pulley has clouted the sensor
Anyway, managed to find the washer and put it back in, (think I got away with the sensor as it still works but ordered a new one just incase) and the problem remains.
Starting to think the spacer isnt standard and is covering another problem (damaged casing/mount?), and in turn creating a misfire at high revs, as the gap between the sensor and pulley **** is too big? Make sense?
Im going to try 1 washer at a time, hold it in place and get matey to crank the engine (by HAND this time) and stop adding washers as soon as it clears.
Does any of this make any sense, or am I barking up the wrong tree?
Any help much appreciated.
