MY ENGINE LIGHT CAME ON MISFIRE

2006 Chevrolet Colorado • 70,500 miles

My engine light came on and had it checked it said piston #1 was misfiring so I had a tune up done and after it said piston #3 had the codes cleared rechecked all plugs and it went away now it is back and saying random misfire. What do I need to do? I don't get it?


changed the plugs and wires

Sounds like you are having a problem with mixture and the computer is getting confused, Have you done a fuel pressure check?
