The car is a 1995 VR6 I've done some searching around on the forum and learnt a lot - but i just want to get some views before i invest in a new fuel pump. Here's a detailed description of the issue - some of these points may be red herrings: - Unfortunately allowed the fuel level to get very low then filled up with a full tank of BP unleaded [normally i only use optimax] - 11 miles later whilst driving on the motorway at about 70mph the car started to lose power, then was jerking around like a kangaroo! Pulled the car on to the hard shoulder - turned it off and on again and then it seemed better. - Drove another 100 miles that day, mainly motorway driving with slight hesitation esp when starting in first gear and also with low revs in second gear - car pulled and ran fine for most of the journey. - My friend who was in the car during all this said he'd had the same issue on his golf 16v and injector cleaner had helped. - Next day replaced the fuel filter and tried again - still serious hesitation to the point of almost stalling when pulling away. Once above 2500rpm power is good. - Then added injector cleaner which made about a 50% improvement with this issue - hesitation felt far less. But still present - also at high revs (4000/4500rpm) in 4/5th hesitation is felt. I think its the crap at the bottom of the fuel tank getting in to the fuel system. I had hoped the cheaper options of new fuel filter and injector cleaner would cure it - but its still there. Would adding injector cleaner again to the next tank full be advisable? Or is it bad to use it too often? Does it sound like the fuel pump is on its way out? Is there anyway to diagnose this before i pay for the fuel pump to be replaced? Could it be something else such as spark plugs? Any help appreciated :roll: I should add that the idle is very stable and smooth - it idles happily at about 600rpm and also the car fires first time without issue.
