hi have tried lots to fix this all ovious like leaks and valve timing i paid someone (mobile diagnostics)to look no solution!has anybody ever had a problem like this or somthing like this as am all out of ideas now and loosing hope on it please any help very welcome.
prob is vacuum is low giving poor economy\rough idle have checked valve timing/leaks/cylinder compression/all seems fine but low vacuum remains and is steady low reading indicating a problem common to all 6 cylinders!only other thing i could think off is ignision timing so i tried new dme,no change am out of ideas now.
hi using a draper vacuum tester and am told higher reading i.e 22 is better as on gauge is showing engine condition on idle is on red meaning poor engine condition!but as i said before compresion test comes up ok!
hi idle is about 850 and very lumpy,has always been like this since i brought it i personaly have tried lots of replacment parts it was the mobile diagnostics that brought this fault up he was convinced the valve timing was wrong(checked it was 1-2 degrees out so put right )problem remains he came and had another look and suggested bottom kekway/woodruff key also checked all is fine so am now lost!!!!
