Re: Fitech issues
Good advice on the fuel lines but lets get back to your problem. I have been running a FiTech system for 3 years. I love it. I live in the United States and drive my car every year from Illinois to the Dream Cruise in Detroit, Michigan. About 300 miles one way. I have never had a problem when driving.
I experienced a problem last year, when I also wanted to clean up the engine compartment. I have a 69, real Z/29 camaro. The car comes from the factory with two ground wires from the firewall to the each valve cover. There are additional grounds from the frame to the front fender wells and some other areas. I removed valve cover ground wires as I did not like the way they looked. After that, the car would buck and not drive well at all. I did everything I new to try and fix the problem. New fuel filter. Checked the ignition timing, distributor cap, rotor, wires and plugs. Still the same problem. I re-installed the ground wires and the problem was gone. Never to come back.
My suggestion is to put the grounds back where they were. Make sure each contact area is clean and the ground is tight. All of this new computer controlled equipment is very sensitive to grounds. Give that a try.
