Wel lads, as above engine wil not pass 5k when driving. it wil hit the limiter wit a slight hesitation at 5k only when car is under no load.Engine idles an climbes to 5k 100% but den starts to splutter an fart! Ive tried every ting i can think of!
If any body has any suggestions, id be very greatful. :)
boost leak? Split intercooler joiner?
Ive had the fmic off and checked for leaks. ive gone over all the vacum lines. ive changed fuel pump, afm,and pretty much every other sensor and solinoid.
ya my bet would be on intercooler leak
wudnt say it would be an boost leak maybe faulty actuator ?
any joy with this since aidan?
No joy yet mick:confused:Quote:

Try the gearbox speed sensor a guy I know had a similar problem. Something to do with the ecu getting conflicting inputs from the gearbox and cutting the power.
plug out the lamda sensor and see if it reves then!!!
afm maybe?
the afm was changed on it before it's last run in mondelloQuote:

new plugs fitted yesterday,coilpacks changed for a known good set
o2 sensor changed,actuator changed/doesn't seem to be any boost/vacuum leaks
any more thoughts lads:huh:
Is it actually limiting at 5000rpm? or just revving to 5000rpm and not revving any further? Has it normal power up till 5k? Whats the spec of the car?

try your fuel filter
i had a similar prob like this before and it turned out to be my air filter wasn"t restricting the air enough,,, silly but true changed the air filter then she ran fine... was after i changed nearly every part on the car...plugs afm coils fuel pump filters inter cooler pipes the lot... ended up getting a mad notion to change the air filter for some reason then it worked///
check all your plugs are tight if one were to come loose it would spark all over the place causing detonation... hopefully you find it
