DR-18: NO FAULT CODE MECHANICAL TEST

At this point in the driveability test procedure, you have determined that all of the electronic control systems are operating as they were designed to. Therefore, they are not the cause of the driveability problem.

The following additional items can not be overlooked as possible causes of a driveability problem.

  1. THROTTLE VALVE AREA - Dirt or ice buildup causing rough idle and stalling.
  2. ENGINE IGNITION TIMING - Must be set with timing terminal grounded.
  3. ENGINE VACUUM - Must be normal for your altitude.
  4. ENGINE VALVE TIMING - To specifications.
  5. ENGINE COMPRESSION - To specifications.
  6. ENGINE P.C.V. SYSTEM - Must flow freely.
  7. ENGINE EXHAUST SYSTEM - Must be free of any restrictions.
  8. POWER BRAKE BOOSTER - No internal vacuum leaks.
  9. TORQUE CONVERTER CONDITION - May cause very low power at breakaway or high speed (only 1 condition at a time).
  10. FUEL CONTAMINATION - High alcohol or water content.
  11. FUEL INJECTORS - Rough idle may be caused by injector wiring not connected to correct injector.
  12. ENGINE SECONDARY IGNITION CHECK - Any abnormal scope pattern.
  13. TECHNICAL SERVICE BULLETINS - Any that may apply to vehicle.
  14. HOSES AND FILTERS - All air intake piping and vacuum hoses must be in place and secure. The proper air filter element must be used.
  15. Must be correct specification with no vacuum at the regulator, 48 PSI on V6 & Non-Turbo 4-Cylinder and 36 PSI on Turbo engines.
  16. COLD FAST IDLE AIR VALVE - V6 and DOHC engines: Coolant must circulate through this valve (mounted on the throttle body).

Any one or more of these items can give a driveability related problem. They can not be overlooked as possible causes.
