Miscellaneous Component Or System Checks
Check the following:
- Check Mass Air Flow (MAF) sensor. Go to TEST DC, step 25) under SYSTEM TESTS in SELF-DIAGNOSTICS - EEC-V - GASOLINE & NGV article.
- Check secondary ignition system. Go to TEST JB, step 1) under SYSTEM TESTS in SELF-DIAGNOSTICS - EEC-V - GASOLINE & NGV article.
- Check fuel delivery system. Go to TEST HB, step 1) (Natural Gas models), or go to TEST HC, step 1) (all others) under SYSTEM TESTS in SELF-DIAGNOSTICS - EEC-V - GASOLINE & NGV article.
- Check exhaust system for restriction. Go to TEST HF, step 1) under SYSTEM TESTS in SELF-DIAGNOSTICS - EEC-V - GASOLINE & NGV article.
- Check PCV system. Go to TEST HG, step 1) under SYSTEM TESTS in SELF-DIAGNOSTICS - EEC-V - GASOLINE & NGV article.
- Check EVAP emission system for blockages (engine stalls) or leaks (excessive fuel odor). Service appropriate symptom under SYSTEM TESTS (EVAPORATIVE EMISSIONS) in SELF-DIAGNOSTICS - EEC-V - GASOLINE & NGV article.
- On A/T models, ensure transmission is functioning properly. If engine stalls during transmission engagement, check transmission solenoids. See appropriate DIAGNOSIS article in AUTOMATIC TRANSMISSIONS.
- Check engine mechanical condition. Check compression, camshaft, valve train components, etc. and repair as necessary. See appropriate article in ENGINES.
- Check air intake system. Go to TEST HU, step 1) under SYSTEM TESTS in SELF-DIAGNOSTICS - EEC-V - GASOLINE & NGV article.
