So me and a few other friends of mine installed the RXT clutch and flywheel from McLeod and after driving it for a day or so my Check engine light came on and then went away and a few minutes later it was back and my engine bogged down until the check light stopped flashing and then i would get the power back, now it says #2 and 8 cylinder misfire and i heard about doing a Crank relearn and i called ford and they said if the car is tuned then they cant do anything for me, but i dont think thats the case, so do i need a new slave cylinder or what i really dont want to take it apart again and try and guess what the issue is and then take it apart again cause it wasnt fixed i guess what im saying i hate doing re-work and its already looking that way.
