Hi All,
Missus VS V6 (auto) has developed an intermittent miss/stumble.
First started doing it only at idle but cleared as soon as you gave it some revs, now it's doing at idle and under load, however it seems to clear itself randomly and then run fine. Car has 202,000km's and MACE bolts on except high ratio rockers
Just before the problems started I had changed the oil filter (high flow unit) and filled the car with 20litres from a fuel container that has been in the garage for about a week. Missus has commented that the car felt gutless in the last week (full tank of 91 gas last weekend, same batch as the 20litre fuel container). I had considered a batch of bad fuel but I can't see it causing these issues?
About the only thing that hasn't been changed on the engine in the last couple of years is the CAS, everything else has been changed. Checked the fuel pressure and it seems fine at about 40psi at idle. Seeing about 14volts at idle at the battery so I don't think it's a voltage issue either.
I have a new fuel filter that I'll fit as soon as it stops raining.
Thoughts??
Cheers
