OK first I was on the highway driving my car on stock boost really not beating the **** out of it. Anyway I;m driving so im in third geat I hit it and shift at like 6500 to fourth when all I know I hear the engine hit rev-limiter! I realized that it went into second my mistake! After replacing a ripped coupler which I thought was the problem the car still idled bad like it was missing. After diagnosing everything I realized I am getting 0 compression on the last cylinder which is pretty weird because like a few days ago they were all 155. The other three are still 155 but the last reads 0. I tried oil and it did not raise the compression. Can it be a broken valve, or a head problem? THE CAR DOES START FINE AND RUNS FINE OTHER THAN THE STUMBLE AND BAD IDLE AND WHEN I PULL THE 4TH COILPACK OUT IT MAKES NO DIFFERENCE!!!!


THE REASON IT WENT INTO 2ND INSTEAD OF 4TH is because for some reason the stick is sticking to the right when being shaken in neutral but I changed the shifter today to a B&M but no difference is their a bushing or something that can be the problem???

PLEASE HELP I DONT KNOW WHAT TO DO!!!!!!!!
