The check engine light came on the other day on my 98 Trooper. I took it to the local auto parts store to scan the codes and it told me I had a "random cylinder misfire" :gunt: . This immediately told me that I need a tune up. Now, on the Isuzu 3.5 engine there is no distributor and as I have never done a tune up on this type on engine before I was wondering if anyone here knows what I need to perform a proper tune up on this motor? Besides the plugs. The engine does not have plug wires in the traditional sense, it has what looks almost like solenoids over the spark plugs with a few small wires running from them to the computer. If anyone can help me out with this I would greatly appreciate it. Thanks. I have to have emmissions done this month and they will not run emmissions with a check engine light on.
