I have a 97 deville concours with northstar that keeps giving me a P0300 code and SES light?


wrong
cars seldom idle rough when warming up if the injectors and electronics are in good condition
P0300 refers to random misfires which is the rough idle when warming up
the history in the fault codes is the fault report generated but not maintained as the fault rectifies itself
the ses is probably telling you to service the system--clean the injectors , fuel filter or check fuel pressure

Starts up but runs rough, exhaust smells, and when you give it gas it wants to shut off.

Check engine light was on. Connected scan tool, got data below and cleared faults. drove car 5 miles, check engine stayed off. p0300 random multiple misfire detected p0325 knock sensor 1 circuit...


If the check engine light stayed off then that means that those errors are not present at this time. It is not un common to have intermittent faults but I would not preced any further until the light comes back on. Then re-scan the code see which are to begin diagnostics.

Service engine soon


Hi .
Your service engine soon is telling you you have a problem with the fuel injection system .
The management system has pick up a fault within the system that needs to be diagnosed, this is done with an OBDII diagnostic tool that most local Shops have and of cause your dealer .
Small example.

---------------------------------------------------------
Check engine light comes on when the engine management system has detected a problem with the emission system.(fuel injection).

When the light comes on the ECM will store a code or codes in its memory for the testing technician to retrieve and decode,

After decoding he will be able to see what problems you are having with the fuel injection system.

He
]9 will retrieve codes like P0300 or P1304 (example)

Code P0300 is a random misfire, from this he will see where and what he will have to diagnose .

If you are having a misfire then to long driving like this could cause catalytic converter damage ,

If you have a simple problem like a knock sensor then you could drive around with out to much problem.

Hope this has answered you question .
Kind regards Indy
