I recently acquired a 90 turbo11, it ran strong for a week or two then one day while pulling out onto the road it just died. I was able to start it again but it the idle was rough and I had to keep the revs up or it would die. All power was gone and it backfires like crazy. Since then it wouldn't start so I changed the plugs, wires, and coils, I deflooded and it started again but ran the same way... Any ideas? I'm new to the rotory engine and just want some info on possible problem areas or where to start troubleshooting..I also realized my o2 sensor wire is cut and I'm not too sure where it connects to. I'm sure the car has been running super rich as a result. Iv'e never unplugged any sensors or modded or removed any vacuum lines fyi... Thanks

check your intake,it may have a boost/vac leak.
the stock IC likes to hide any hoses that may have popped off.

Not familiar with the TII, but if it were an FD I'd suggest checking the boost sensor's vacuum line...after re-connecting the O2 sensor.
Have you downloaded a copy of the Factory Service Manual (FSM) yet? It probably has some trouble-shooting guides and may help you find the line to the O2 sensor.

I do have the fsm on my computer I'll check it more thoroughly for the o2 wiring....I have double checked the hoses under the intercooler and intake...do the case and mas go bad often?

Sounds fuel related, maybe injectors. Did you check the TPS?

I was happy. Reasonably priced, quick turn-around, new pintle caps and 'O' rings and before and after flow readings.

Witchunter is a good injector cleaning shop too. Will cost about $100 altogether with new orings and everything.
