Okay, here we go. 1989 Coupe. Was running great. Then it felt as though I had gotten some bad gas. Started getting sluggish. Filled tank and added Lucas. Not much help. New plugs, cap, rotor, fuel pressure regulator, gutted cat conv. Running extremely sluggish. Now power under load. Seems to get weaker and weaker the further I go. ECM? Pre cats? I'm at a loss.
tested ignition control module (distributor), it started faulting once it was tested a few times and heated up. I replaced it today. The car ran better, but still no where near as good as it should. It threw codes 13 and 22. oxy sensor (which has already been replaced) and TPS circuit. Tested .55 volts (within specs). Could the ECM make it behave this way? Can an ECM be tested?
Just ohm tested all injectors. the engine was not cold, not quite warm. not driven for apporx 3 hours. most hit .012 or .013. one hit at .010 and one at .005. could this be bad enough to make it run this poorly?

Look at the injector sticky at the top. You probably have other issues, but I would start with a new fuel filter and injectors. Get them from Jon at FIC!
When my Catalitic converter broke apart inside and started to clog up my power started to go down also.. Just a thought since you may have more then one problem going on at the same time..WW
