Hi all,
I'm curious if anyone has had this or if they know someone that has.
The car is a 2000 2.5 V6 Vectra new engine fitted 2004 low mileage, 3.8 Bar FPR, Induction kit, twin cat back sport exhaust - rest is standard.
A week or so ago I was driving up a hill about 60 - 70 and it has a sharp brow, I came over the car had lifted and came down with a thud.
The engine had loss of power and a rattling noise, bit like messing gears - this went and hasn't returned for well over a week, came back today.
I have tried blanking the EGR valve - as that can make a similar noise and removed the Bosch Super 4's, as they were fitted a few days before. I have checked the Cat, manifold and sensor connections, there are no warning codes logged.
I had added Cataclean - not sure if thats the problem.
Now I read somewhere about an engine retarding and a strange noise, it was fuel related, have added Redline - no difference.
I described the symptoms in another forum and have talked to my local garage who have ruled out cambelt - engine done 11-14,000 miles, there's no overheating - so it isnt water-pump bearings, PAS pump works, no clutch slip - my garage can't give a definate answer as the noise isn't there all the time, as the car purrs like a lion normally.
The noise isn't there until I push the car it then comes back, so I am wondering fuel filter as if I push it again it goes away.
Any thoughts?
