Gas is over a year old, and I have a massive fuel leak pre filter so its not very fresh gas either.

Oh mark, what is a DRBII? <img src="/forums/images/graemlins/confused.gif" alt="" />


You probably want to start here. This is the factory diagnostic manual. Read the section on drivability tests.

A DRB-II is the factory diagnostic tool. With it you can...
  • check the injector circuits
  • check the o2 sensor
  • check the engine temp sensor
  • check the air flow sensor sensor
  • check the engine rpm
  • check the air temp sensor
  • check throttle position sensor
  • check the crank angle circuit
  • check the air pressure sensor
  • check the fuel pump circuit
  • check the EGR temp circuit
