Just a quick note about a problem I have which I sort of solved...
2001 Y DTI Astravan 107K (no frills- OK maybe Central locking!)
Original problem: Hunting while ticking over. Should have been 850rpm but more like 400 then 1100rpm. No codes on the pedal test.
I thought Fuel filter, so I changed that for a Mann one from ARE. Worked fine for 10 mins then died in the middle of Aldershot. I looked in the fuel filter house and it's half full of fuel. Got a tow back from a very kind total Stranger.
Logically you think something else is causing the problem, fuel pump , fuel lines, injectors, i.e. expensive, expensive and expensive.
Temporary Solution: I bought some clear plastic tube from the local brewing shop (It's used for draining demijons) and connected it to an inline fuel filter and watched the bubbles go round. The vehicle ran fine and didn't splutter once.
I then went to Vauxhall for a proper GM fuel filter, put that in and it coughed and spluttered and died. So'now I'm running back through an inline filter with proper fuel pipe.
Conclusion: I have some how damaged the top of the fuel filter housing and it's letting in air.
Any ides, apart flea bay for a new fuel filter housing.
