I am just after a little brainstorming if possible please . I Own a garage and i had a 2006 Vauxhall Astra estate z18xe dropped into me with a snapped timing belt.
Now after the rebuild we have the car started and it is currently purring like a kitten at idle, except, There is a severe lack of power when in drive (automatic) and the engine will not exceed 4000rpm.
P0335 - Crank Position Sensor and
P1700 - Transmission Control Module, MIL request - Malfunction
I have checked wiring etc following head rebuild and everything appears to be connected and in the correct place - i have also replaced both crank and cam position sensors and have also tried an AFM to no avail.
I am now at a loss! If i have missed anything out then ask me and i will answer as best i can.
