Try to make this concise and precise.
Car is a 5spd 90 LX hatch with a v1, systemax heads, intake and (I believe) cam, long tubes with stock gears. There's some sort of canned tuner on it with a knob to select tune. This is my 2nd summer with the car, before now only changed fluids and plugs and thought about how to fix the wiring mess,
Began starting hard when warm about a month ago and then died on me while driving: no tach and no spark, also found the battery was about to go.
Tracked it down to a bad TFI using the guide, so I replaced coil, cap, rotor, plugs (gapped to .043) and wir.es (wish I had just change the dist too)
Had a real hard time setting the timing (had to rotate the dist 70* to remove the TFI). SO cleaned the balancer and put a big yellow mark on 0. Set my timing light to 12 degrees advanced and tried to have the car stay ~900RPM, it idles poorly and very rich. I noticed the plug that advanced timing removed from the dist. and there was a block off plate on the dist where it should go (pic attached). work around for bad tuning?
Any rate, starts pretty easy but misfires or knocks hard, especially when you first dip into the throttle. I've tried going back a few degrees and foward a few and it seems to run poorly either way. before I take out the plugs and reccheck the cap, what else shuld I look at?
