I have a 1991 Mitsubuishi mighty max truck . The truck runs fine until I drive for about 1 mile and then the check engine light comes on and the truck starts shaking , but does not lose power.


Hi, I own an 86 Mighty Max truck myself. Is there anyway you can get the code number for the engine light coming on. It could be many things that cause this problem. Fuel filter, EGR, Clogged Catalyst, Sparkplug Misfire, Cracked Distributor Cap, the list goes on. It needs to be determined if the problem is fuel or electrical related to help diagnose the problem.

Hi Bennie, When did you last replace the fuel filter? I believe a service may be the answer to your problem. If you have carried out a service recently, try replacing the fuel filter for a better quality product. Regards John

Truck had a very bad idle, code 300 multiple misfire, I changed the plugs, wires, distributor shaft, cap, cam pos sensor, crank sensor and the computer. Truck will start and idle fine for a few seconds...


What year is your truck? if it has a "vortex" engine in it then I would suspect the fuel injection system. The Vortex uses a spider web design with a central block and distribution liners that clip into the head. the tips are known to clog in the bores. Take the whole spider web off and spray the tips real good with carb cleaner and then clean the bores before you put it back together.
