I don't know why the codes comes up but it doesn't cause any operating issues. Your plug wires or boots may be at fault. Here are some things to check. First, use an old plug to check/confirm that the plug wire connector snaps onto the top of the plug. The boot slides on the wire and if the boot is too far down on the wire (or, the wire is pulled too high up in the boot) then the metal connector will not contact the plug properly and a miss will develop. Next, check the resistance of the wires. You need to measure the length of the wires, too, so you can calculate "ohms per foot". I don't remember the ohms/ft range that is OK but your wires should all be within the same range. If one is much higher then you need a new plug wire or two. Next, confirm that you have the plug wires on the correct coil pack terminals. It is easy to get them fouled up. Last thing is to confirm that the inlet air temperature sensor is plugged in the intake tube, there are no vacuum leaks, and that you have the ECT sensor and the ECT gauge sensor in the correct spots. I did find pp_puncher's quip about lowering springs to be amusing. Our model years do have a 4x4 look. Chris</blockquote>
