the cars come with many diff. engines. and EFI systems that match it.
so cant help you.
but ill answer in pure physics.
1: lost DC 12v power to the EFI system causing spark and fuel losses.
2: lost engine compression. 1 or more cylinders.
3: lost spark or never doing a full tuneup every 60k at least.
4: bad fueling, too much or too little.
what do do is a few simple tools to discover the truth.
I had the same thing happen to my trooper it started losing power I had to cut out the cateyletic converter and when I did it ran perfect but it was very loud but I only drove it to Darryl's Mufflers he put a new one on she ran like a champ it started to plug up or it could be the timing belt slipped a little, jumped a tooth it would still run depends on how many teeth that it jumped the more teeth it jumps the more it will loose power fast and eventually start missing and back firing and start being hard to start or it jumps to far out of time it will not start at all it will just turn over. If it breaks it will turn over fast and not fire at all. Hope this solves your problem its 2 problems that I know will make your trooper lose power and speed if this does not sound like the problem then call Affordable Battery & Auto Care and ask for Jed let him know Jeff referred you to him and he will look it up and help you diagnosis your problem. Call 503-477-9631 he is really good and he is affordable.
put the key in the ignition and turn to the "On" position. Once one of the doors is opened you have about 30 seconds (you should hear a "tick-tock" sound as it counts down) to put the key in the ignition and turn it to on. If you open the rear gate, the alarm will immediately sound (this is by design). You can buy new fob's online for $40-60 each, google how to reset them.
has this model got coil packs on it ? also does it try and start at all or just nothing at all. can only be in the distributor or computer now you got all the other bases covered. fuel ok spark plugs ok spark plug wires ok .. now coils or distributor has to be it . jerry
