well you answered my question and was told it was probably the spider injection system and I replaced it with an up-graded version and well after doing all of that the no.4 cyl mis fire code still pops up when going down the highway. The code was cleared also after install of the spider injection.I lost the info for my login and password so could you foward this to the right people to see if they have any other answers to this problem. The truck only has 55,000 miles on it
Checked plugs and they look the same (clean and not black or sooted up) The light will go off after driving around city a few days but if you drive it back on hwy for a while at around 2000 rpm the light will pop back on. If the computer was messed up with that inj. Wouldnt the light be on all the time?
have the same problem?
