I've been having some trouble on and off for a few months now. I'd get to about 3000rpm, and the powere would fade. Still enough to cruise at 65/70, but no acceleration, feels like the turbo had gone. As time has gone on, I appear to have lost all use of the turbo, car is extremely flat and sluggish.
Last Thursday, car stalled at an island less than two minutes from home. Stopped, turned off, waited and restaredt after 1 minute. Got back, but whilst turning round to bring car facing back the right way, stalled three further times.
Drove into work ok in the morning, then i dropped it into the garage next door to work. They diagnosed it as split vacuum hoses. replaces two? then ran it, and ran fine. I drove home, car had more life and grunt than I remebered. Got some real acceleration back now.
All was well until the following day. After a bit of toing and froing, from shops, to mates, to parents, etc car lost all power again. Once more, I was minutes from my folks, so pulled in there. Went back half hour later, ran fine again.
Drove ten minutes back towards home, around a couple of minutes into the journey, power flickered for a minute, but then recovered to take me home effortlessly. Stopped off at the shop fo0r a couple of minutes, tried to restart the car, and it sounded like a tractor. Engine pitch had dropped and sounded very tinny/rattly. Stalled as I pulled out of parking bay. My wife walked our daughter the few minutes back home, as I tried to limp the car home, she said it was that noisy she could hear it in the next street.
That seems to have been the genaral theme. Runs fine, but as car warms up, power flickers, and either stalls then sounds like a 1980's transit van, or I manage to ease it through carefully without any further stalling.
Took it back into garage today, they said the vac hoses are fine, but the note of the codes they gave me says -
P0335 - crankshaft position sensor - circuit malfunction.
P0340 - camshaft position sensor A circuit (bank 1 or single sensor)circuit malfunction.
Can anyone point me in the right direction, before I have to bite the bullet and take it to the local Vauxhall dealer and part with some more serious cash, or realistically is that my only real option left....
And please allow for the fact that I am absoloutely clueless regarding mechanical issues with cars... so nay hints or tips need to be in as basic a language as you can... or at least something repeatable to my mate at work.
