I will start by saying I know very little about engines. After going through all wiring test theywited for some type of adapter that connects to the glow plugs and checks compresssion that way. Each cylinder had 380 except for 1, it had 80. GM has now told them to pull the engine out and take the heads off. The dealership nor GM has any clue as to what caused my problem but I guess I wil just have to keep waiting. The only frustrating part is I have only driven the car about 2800 miles and they are giving me a hard time about something to drive. I guess I am lucky we own a body shop and the rental companies give me something new to drive everyday. Edited by: rpbdawg
