I found the problem... it was a very bad batch of fuel. So I drained the fuel tank and did the filters. The fuel I was using was V-POWER now I will only use BP ULIMATE. Thanks for all your suggestions and help even including the wife jokes
Ok on the highway surges and misfires doesnt rev past 2000 rpm and when it does it just stays there. When I put my foot down hard it it just stops revving. It has a custom tune only.. If this helps.....
New plugs are in and still the problem of the running like Clean Throttle Body...Check New Plugs...Check New Coils....Check New Air Filter....Check Now I'm out of ideas
