fuel pump... fuel filter....probably need to be changed. 300 bucks worth of parts probably 2 hours to change out... | ||

I'm not saying it is your fuel pump, but I had the exact same symptoms on my 96 and after troubleshooting, found my pump was bad. Changed it, everything was right with the world again.  You might want to search the boards on how to test and troubleshoot fuel pressure problems, there were several threads that helped me isolate it. joe | ||

Assuming your fuel pressure is ok, I would firstly give it a basic tune-up. Stuttering can be faulty plug wires (leads in UK English). I have had this before. On the rough starting, other than the ignition tune-up, suspect clogged fuel injectors and intake valves. Buildup on the valves soaks up the initial fuel during startup. I used some Lucas fuel treatment and was shocked at how much better my Rangie started running (117K miles). I think BG44K would be the best choice - available at GM and some BMW dealers in the US. Miss at idle disappeared and fuel economy up 1+ mpg. | ||

Plug leads are new, fuel filter too. For a start I'll use BG44K, and have fuel pump tested by some auto-elec place. Recalculated fuel cons (used to L/100km in SouthAfrica): 11.0mpg !!! (Can anybody match that? :-/ ) Both my previous Discos did 16mpg... |
