Question about 2002 Isuzu Trooper
Ok it sounds like they don't no what is wrong so there are just going to start replacing everything. It could even be the coil packs that gives your engine spark. Anyway there are 3 things "ECU" which controls and monitors the complete injection process. The 2nd "Rail pressure control valve" which is just a valve that opens and closes to let fuel into your engine. And 3rd the "RPS" (Rail-pressure sensor) which delivers all the measures valves that are required in the process. I would have a shop check the coil packs, RPS, and ECU before you go buying anything else that doesn't need fixing.. :) Good luck man!

In my opinion they should have test drove the car after replacing the injectors they would of found that the vehicle lacked power and wound have finished fixing it. This is not all the dealers fault. Parts and labor being as expensive as they are they fixed the miss but not the lack of power, And since you or they did not know the regulator was bad the mechanic brought mistrust on your part by doing a dis-service by not road testing it after repair to confirm it was fixed. This is not a rip off just didn't complete the job. Had they found the fuel rail regulator bad you may have thought they were trying to jack up the prices to so it's a catch 22. Darned if you do darned if you don't. The fuel regulator will not cause a miss just a lack of power.
