Multiple repairs have been done, and now the on-board engine checking system has proved useless.
Issue 1: Idle Air Control Valve Malfunction (Plunger stuck open)
Solution: IAC Valve replaced completely, did not clear code. (Aftermarket BWD)
Issue 1.1: Mechanic suggested EGR valve may be faulty and causing IAC valve to stay open.
Solution: EGR Valve replaced completely, code cleared. (Aftermarket BWD)
Issue 2: IMRC Valve Stuck Open
Solution: Completely replaced IMRC directly from Ford, code cleared.
Issue 3: O2 Sensor circuit malfunction, Bank 1 Sensor 1; O2 Sensor circuit malfunction, Bank 2 Sensor 1.
Solution: Both sensors replaced with Bosch aftermarket sensors, codes cleared.
Parts Total: Roughly $600
I had figured that after doing all of this, the engine would run okay, but the problem remains. I cannot accelerate effectively, which is making it very dangerous to pull onto roadways and highways, nor can I get anywhere further than 20 or 30 miles away in a short amount of time.
The engine is no longer giving codes, but it still having issues. I prefer to do these things myself, but I'm getting to the point where I may have to bring it to a mechanic, and practically shower him with money.
My current theory, after doing a lot of research on ford repairs forums, is that there is a problem with the Catalytic converters, which is dreadful to me considering how expensive they are.
have the same problem?
