Firstly Im new to this so please take it easy with me :-)
OK, I have a Corsa C 1.7 turbo di diesel that has started to loose power from time to time. its intermittent. at 1st I though the wastegate might be getting stuck open but after much thoughts I dont thin it is becasue of the following,
up to 2.5k rpm power torque is normal
after 2.5k power loss and the engone does not want to rev. Its as iff theres no fuel going in....... if it was the waste gate it would still rev off load (well I think it should....)
It happens every now and then but seems to be getting worse ythough yesterday I did 55 miles and noting it was fine and then on the return trip within 5 miles it had lost power after 2.5K rpm.
No ECU light apperas, though from talking to people in general it seems quite a common problem with this engine set up. Has anybody had the same problem and if so what do you recommend?
