Hi everyone, been having problems with a customers car, basically his brother a so called machaniic mucked about with the cam timing on it an got it a tooth out, i thjink from memory the code was 00515. I have reset all the timing marks and reset the dizzy by turning the engine to top dead on no 1 and fixing the rotor to number 1 on the dizzy. All the codes where then cleared and the car ran great revved righ round. Sorted or so i thought as soon as the car was stopped and restarted the fault would re appear. I am a little stuck now as i have come across this problem before and been able to fix doing what i have done but not this time. Everything else seems to be working fine and prior to the cam timing being altered the car ran okay so i dont think its a sensor issue Any ideas
