Hi all i hope someone may be able to shed some light on this issue
I have a dec 2000 zd30 which has performed faultlessly until recently
The engine starts and idles as per normal, when it is driven it starts missing at about 1800rpm, change up a gear and once it is fine until 1800rpm and so on.
I had the diagnostic errors read and the only 1 that showed up was caused by me from when I had removed the maf plug.
I changed the fuel filter, slightly better maybe
I bypassed the fuel filter and lift pump, this appeared to fix the prob so I fitted a new lift pump, test drove it and the prob appeared gone.
The next day I went for test drive, after about 40km highway driving the missing reaccured.
Replaced the flexable fuel line to and from the fuel filter in case air was sucking pass the old hose clips, no better
Replaced the MAF sensor as the voltages were not correct on the old unit, this seems to have made a difference to the engine, appears to run much smoother but has not fixed the engine missing.
I feel the prob is either lack of fuel or air in the fuel line.
Hopely someone has seen or had these symptoms before and can help
Cheers jim
