Question about 2003 Chevrolet Impala
With out a diagram to show you this will be difficult to explain so bear with my explaination. Starting from the passenger side of the car reading to the drivers it is 6,3 2,5 4,1. Now for where the wires go. The spark plugs you can see( front) are 2, 4, 6 reading the same same way passenger to drivers side. The other side 1, 3, 5 reading from passenger side to drivers side. I hope this helps. You probably need a fuel injector to correct the original problem.

engine light comes on and off, these are indication that there is some
error code stored in your vehicles ECM. The engine module computer
needs to be scanned. These will give the code and as per the error code the
further problem can be detected and confirmed. The engine light
indicator blinks or remains steady on dash when engine computer
noticed any problem with any engine electrically operated components.

you know more about which areas to look, check, when there is engine light

When the service engine soon light (Also called the check engine light) is turned on this is to alert you to the fact that Powertrain Control Module (computer) has detected a failure somewhere in the systems it controls, this can be the transmission or the engine or emission system, there are fault codes set in the modules memory for these faults. What needs to happen now is to have the powertrain control module scanned with a special tool called an OBD2 electronic engine control scanner or a OBD2 code reader. Once the code(s) are read then you must perform the diagnostics for each code and make the appropriate repairs based on the findings of the diagnosis that was performed, this is called doing "Pinpoint" testing.
