VL engine hezitation
Hey guys.
I recently bought myself a VL SL commodore n/a RB30 with the 5 speed. She was just sitting in some old ladies garage with 98,000km on the clock.
Now, there are a few little niggles that its got.
- There is a buzzing noise coming from the fuel pump (external) when i start up. Is this normal?
- At about 60km/h there is a really high pitched squeal coming from the same general area. What do you think it is?
- It runs fine when idling and when i slowly bring the revs up in neutral it still runs fine, but when accelerating it feels and sounds like its running on 5 cylinders. I replaced the fuel filter and put in some injector cleaner and it ran perfectly for one day but then went back to its nasty habits. What could this be? Im thinking maybe it has something to do with the fuel pump, maybe the afm, maybe dirty crappy fuel left in the tank? But i honestly dont know.
Please help!
