Spark plugs, Ignition wiring, ignition coil, or high tension cord may be faulty. They must be inspected one by one and replaced if necessary.

You have to find the reason the check engine light is on. This will aid in diagnostics. Also, are you buying fuel at the same place both times?

Got a 1997 Chevy Suburban 5.7 liter 4 wheel drive and the check engine light is steadily on. I not too long ago changed the spark plugs and just changed the EGR VALVE. As I drive now it's running rough....


What you do when the engine light comes on is to stop the vehicle ---check the oil level and let it cool down then check the coolant level at the radiator. The engine light is the message to you that the CPU has found sensors /servos that have gone outside set parameters and your course of action then is to prove that the engine is safe then run the fault codes to find the recorded faults and fix them . use the code reader to reset the CPU to ensure that the faults are fixed.

Random misfire/rough idle/stall


Low fuel pressure due to faulty fuel pump will give misfire codes due to fuel starving conditions. Have fuel pressure tested, preferably when running bad.

Flashing check engine light is missfire, fuel pump probably causing multiple tries to start.Having to build fuel preasure,vac leak on one side of intake probably causing rich/lean condition.Also check back preasure to cat ,Sound like you are moving down right track.Mas air flow would probably set lean code bank1 and lean code bank2
