I have an 88 rx7 NA. The day before i had to get it inspected i put a new exhaust on the car. Headers back and it was made at an exhaust shop. Car ran fine after i got it back. I was heading to get it inspected the next day and as i was accelerating the car all of a sudden started to miss and run rough. It wont hold idle well and the engine rocks at idle. It has little power throughout the RPM range. I replaced plugs, wires, and the O2 sensor. I tried two different gas stations and put dry gas in the car just in case. My car has been known to flood and i have to pull the INJ fuse and crank it a little then replace it sometimes to start it. Now i have to do this alot more to start it and it starts really slow. Could i have a worse injector problem now? Blown seal? Any help is appreciated.
