So I have a japan spec 92 legacy w/ a missfire issue?

Here is what I have done so far.
-new spark plugs
-new spark plug wires
-left forward cyl is the problem child
-definitly getting spark to all wires
-swaped injectors around and prob didn't move w/ injector

-havn't tried to check injector wire for current yet

Any ideas ya'll might have would be great.

Thanks

Another member with a 91 turbo had the same problem recently. Turns out it was a faulty ignitor.

I had a misfire on my BD.. i replaced the coil, spark plug wires, spark plugs...etc. Car would run a bit strange..but was driveable.. but you could feel the engine shaking around a bit. Turns out the timing belt jumped a few teeth.

check compression as well.

compression is stil at 165, 165, 165, 135. #4 is still within range for not causing a misfire. but #2 is still misfiring as well and the compression is perfect on it. I'm going to see if I can get a leak down test.

I think I has a possibility as to why I have a miss-fire. Now this is only a possibility.
On the picture below I pointed out a part that the guy who did the timing belt install said that I do not need. that it is only needed on turbo engines. I know the picture is of a turbo but the part is the same (not the same number though). Is it possible that this could be the culprit of my CEL's Misfire on #2 and #4....
