Also check the oil and look for a white froth. Also make sure the car is not smoking white out the exhaust ... either could indicate a blown head gasket. If you have a timing light, check your timing.

Check the engine vacuum at idle. it should be 20 inches of vacuum. if not the catalytic converter may be clogged up.

You only have a few choices. Buy a repair manual at a parts store. Go online and google wiring for your truck and you might find it posted for free. Go to Alldata .com and pay for the info you need or ask nicely at a repair shop or dealer that can print off the required info.

SOURCE: Chevy Cheyenne pick-up dash lights and tail lights out.

A blowen fuse will cause that, most all dash lights and taillights on cars and trucks run off the same fuse.

I have vitz 2006, 1300cc, when i starts the car and start driving its response are fantastic mean pick up is excellent and no knocking, but as the engine became hot, the pick became DULL, and engine s


The reasons are follows:
- Contaminated fuel.
- Knock sensor poor performance.
- Check exhaust system. If clogged, remove or replace the honey comb porcelain.
- Check ignition timing with scan tool at idle speed. (5 - 8 degrees BTDC).
- Check engine oil level. If the oil level is low, it may be one of the reasons for knocking, because oil may be burning during the combustion.
- Check fuel pump pressure. ( 41 - 49 psi).
- Remove negative battery terminal for 5 Sec or more. Reconnect the terminal. Close all doors, remove all electrical loads like room light, parking lights, blower motor etc. Start the engine and hold the throttle at 3000 rpm till the radiator fan becomes on to complete the idle speed relearn process. Release accelerator pedal after the radiator fan becomes on, and let it idle for 7 min more.
- Switch off the engine for 3 sec and you can then start and drive the car comfortably.
Hope that works.

From your description of the knocking, mileage, and oil crusted on the intake valves you need an engine or a complete rebuild of the original.

Usually a problem with a dirty throttle body or a faulty idle air control valve. The computer controls idle speed by regulating how much air enters the intake thru the valve.

1995 chevy p/u with 4.3 engine 1500 series.


code 12 is always present in gm motor products. it simply means no tach signal because engine is not running. i would go with the simple first and clean the throttle body real good . that takes care of 99% of idle problems.
