will not rev over 5k

[robiwill]

Right pulling my hair out here

car 1999 Mk3.5 cabriolet with 1.6aft engine

replaced, all plugs all leads coil pack, distributor, all wiring checked, timming checked all ok

fault code is sporadic signal on camshaft sensor. can clear this code but as soon as car hits 5k rev limiter kicks in and code reappears

doing my nut in any ideas or cures

[dan2252]

cam sensor?

[robiwill]

camshaft sensor is part of the distributor hence changed

[dan2252]

i see.. dont know anything about these engines.. you say checked timming is that cam timming or ignition timming? my last car cam timming was out that brought up cam sensor faults

[robiwill]

yes and checked against flywheel too so 100% correct, pleased help someone been told most likely ecu, hoping its not so open to ideas

[dan2252]

does sound like a electrical, ecu problem of some kind i cant see how else it could cut the limiter in :/ hmmmm its a head sratcher that one

[Chris.]

is the car stood still when you try it?

[robiwill]

yes but does the same thing when you drive it hit 5k and rev limiter kicks in. if its ecu its good old ebay and ecu chiped key and transponder but trying to see it anything else first as will be mighty pi@@ed if change all that and same issue, thanks for the help so far and ideas though
