Do it Your self Auto Repair Diagnosis
1Make a list in the symptoms you may have noticed because the dilemma started inside a notepad making use of a pencil. As an example Auto diagnostic tool, engine backfiring Vehicle Diagnostic equipment, stalling, overheating, clicking noises coming from the front wheels, uneven braking any time you depress the brake pedal, etc.
2Describe when each symptom occurs subsequent to every single difficulty you listed in step 1. As an example, possibly the engine backfires at any speed, but the vehicle stalls only when it is actually cold. Does it overheat after ten minutes of driving? Does it only make a clicking noise when turning left but not when turning proper?
3List each of the feasible systems that could be involved in the difficulty you described in step 1, paying special consideration to when the problem occurs as you noted in step two. As an example, when the engine backfires regardless of speed or weather the engine is cold or warmed, your auto may possibly want timing adjustment. In the event the engine stalls only at idle, the idle speed might be incorrect or the idle speed control motor could possibly have failed, or you could have a fault inside the fuel or emission technique.
4Proceed together with your diagnostic at the most logical point inside the system you believe is most likely to be causing the issue. Make a visual inspection of wires, connectors and components within the technique you might be suspecting. Lots of times, a loose wire, dirty connection or damaged element may well be the reason for the issue and is just a matter of adjusting a wire or connector or replacing a damaged aspect. In the event the engine overheats, examine the coolant level and look for signs of leaks around the radiator, hoses and water pump.
5Begin testing the most likely elements you think are involved inside the issue, in case your visual inspection in the program did not turned out any uncommon signs of trouble. By way of example if the engine backfires, remove the distributor cap and rotor and verify them for cracks, carbon traces or other damage. Test the ignition coil making use of your multimeter and after that visit the throttle position sensor. If the engine overheats, verify the thermostat and water pump.
