it took a lot of work and thechecking of anything that be the reason why it was running so bad. One good thing was I didnt buy anything I really didnt need in the way of parts or sensors. It drove my dad and I both nuts. I even asked for help from my younger brother who is a student at Nashville Auto Diesel College. He was stumped. Combined, my dad and I have about 70 years experience working on cars andthis thing drove us nuts. No matter how modern the car is the engine needs 3 things to run, fuel, spark and compression. This one was lacking compression. Edited by: jerald120374
