My 98 E00 is hard to start, shaking, smoking, and losing power I have to pump the pedal and downshift to keep her going also shows battey on the engine screen! In the last 5k mi. I`ve had installed all fuel lines and filter, mass airflow senser, fuel shutoff vavle? and a new waterpump and battery. I`m seeing the fuel running in the line`s I was told this means air in the system would this cause all these problems, also the day after I picked her up after the waterpump was installed, I noticed fuel on the drivway a few days later the other problems started a possible wire cut by my repair shop and they weren`t aware of it or negilance? I also put a small amount of marvel myst. oil in the engine along with my recomended fuel additive.
