well i started started up my truck today n it start with no problem, but i did notice it sounded like a ricer engine with no exhaust since i dont have it hooked up yet. i left it on for a while n only the passenger side exhaust manifold was get hot, n the other was just warm so i checked for a spark on all the driver side cylinders n no spark! so wat could it be? something i did wrong in the harness? or perhaps the PCM maybe my tuner did something wrng?
