i am taking my car to the dealer today..... i have a misfire in 1,3, and 4......... how my car is still running i have no idea the weird thing is that the miss is only at.... idle? i dunno car doesn't feel slower or anything infact i just beat an m3 about 2 min. before i got my tune taken off and my stocky put back on...... weak



btw if anyone out there is tuned and your starting to get used to it and you think you feel slow..... take a ride in a stock ss/tc....... OMG IS MY CAR SLOW AS HELL right now!!!!!!!!!!!!!!!!!

 

Make sure the connectors on the ecm are all the way on. One of mine was loose on Wednesday and all cylinders were misfiring and a bunch of other problems. The car still ran though

 

really?
i'll go check is the ecm right under the driver side dash..... how would i know if **** was in the whole way..... thanks for the info





nope wasn't it..... thanks for the help tho
