Hopefully some one can help us out. I have a 2000 jimmy 4.3 vortech 180k miles. Started misfiring .
Originally threw cyl 3 misfire. So We changed the spider injection unit first, then threw random misfire code. After that , changed cap & rotar , changed coil, same code, changed plugs & wires, came up random, cleared it and drove again came up cyl 3 , changed ignition module, threw a random miss again. Also calls for evap code, and an 02 sensor bank2 sensor 1.
Mind you all parts that we changed were all original except 4 of the 6 plugs.
pulling my hair out with this it's been guessing games. no one can figure it out. only other things we're going to try were the crank position sensor or an issue with the distributor?
