Question about 1993 Chevrolet Lumina

1 Answer

Service engine light on and eletronic spark control failure is t

I am running out of options on this one. I have changed out the spark module and also all of the plugs and wires( twice), but yet I still get the same fault. I have also changed out my knock sensor and had my other sensors tested. The car runs pretty good but occasionally at idle you can feel the engine bog down and then return back to its normal idle. Any ideas I would appreciate them.

2005 gmc savana reset check light after oil change


The Check Engine light has nothing to do with the oil needing to be changed. Please read on.

When the service engine soon light a yellow light (Also called the check engine light or engine management 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 you may not feel any difference in the way the engine runs, 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.
