It sounds as if you either have a faulty spark plug or a faulty high tension lead you need to check the plug and lead on the cylinder that is not firing. If they are OK the only other cause could be a lack of fuel to that cylinder.

Took my 97 GEO tracker to the car wash cleaned th engine and now runs on 3 cylenders


Step 1 is to find out which plug is not firing, easiest way is scan the PC & get readings. Or ck for spark at each plug. May have to pull plugs if all are firing,could be coilpack, wires, plugs. Find out where u are losing the spark.

You might want to look for a vacuum leak on the intake manifold. You also might need to hook up a scope and measure injector duty cycle and compare it with a good cylinder. Also check wiring for chaffing going to the injectors and coil pack. I can provide you with pin out on ECM if you need.

Yes you can, just make sure you put the wiring in the correct order, the best way to do this is change one wire at a time.

I have a 1996 3.8 dont fire in a couple cylenders


Have you changed the spark plugs/wires? A scan will pull up any codes that can narrow the issue as well.
