hi people, ive just bought a 2.5 v6 astra mk3 van and it just wont rev past 4k at all even on idle, the eml has flashed once but went out after a couple of seconds, the engine itself is very clean and all the hoses/pipes look fine and all the gaskets are good,and all the sensors are plugged in, it does have a 3.0 throttle body and 4 bar fpr on it, could they be doing anything bad?
so far the things that have been replaced are:
afm (before i got it)
injectors + rail (before i got it)
leads + plugs (before i got it)
ecu (before i got it)
cam sensor (before i got it)
both knock sensors (done today, no change)
fuel pressure reg (got a 3.0 bar one atm, also got a new 4.0 bar one to go on too)
lamba sensor (before i got it)
coil (before i got it)
coolant temp sensor (before i got it, but also came with a brand new not fitted one too)
fuel filter + lines + pump (before i got it)
new fuel tank (before i got it)
it flashes 2 codes which are 02 sensor and afm - low voltage.....
sorry for the essay but im really wanting it fixed,
any info will be greatly appreciated
cheers, brad

a 1.6 f16 box mate with short shift, its started to not rev past 4k now on idle either unless i go up the rev range really slowly then it goes right round to the limiter, under load tho it just doesnt want to go past 3.5-4k at all and feel like someone has just cut all fuel to the engine...

you are getting two codes for sensors so replace them I suppose.
