P1130 FORD - 9 escort

Question

97 escort. What need to be replaced? code p1131, p1130, p0300

Answer 1

first try to fix the P0300 which is a random misfire. Replace the spark plugs if you have not done it for some time/miles. Use high octane gas 91 or higher (from Shell or Chevron).

-Faulty spark plug (s)
- Faulty ignition coil (s)
- Clogged or faulty fuel injector (s)
- Intake air leak
- Fuel injectors harness is open or shorted
- Fuel Injectors circuit poor electrical connection
- Ignition coils harness is open or shorted
- Ignition coils circuit poor electrical connection
- Insufficient cylinders compression
- Incorrect fuel pressure

the other two codes are related to the oxygen sensors. but fix the P0300 code and than see what happens
