I just pulled this code from the ECU- Random Misfire Detected -. Car runs fine and the light went off after about 10 hrs. I am going to the dealer to see what they have to say. Have only 2000 miles left on my warranty

 

So I went to the DEALER, After I replaced my FRANKENCAR. They pulled the same code "RANDOM MISFIRE DETECTED". Of coures they ran some tests and after 2 hrs told me that it is normal and I can drive it. Went home and the next day I'm getting my SES light back ON. Guess what: It's the same thing!!!!

Can't they just fix this THE FIRST TIME!!! I got 2k left on my warranty and just want to get this done before it runs out!!!

 

Are you talking about the Misfire code for certain cylinders like 0300-0306 codes? Because that tells you specific cylinder.

I looked for the random code and dont see a random misfire code.

If its the 0300-0306 code then it can be spark plug issues, insufficient compression, incorrect fuel pressure, injector circuit is open or shorted, injectors, intake air leak, incorrect pcv hose connection. This is what the FSM says.

Id check two things right off the bat, the spark plugs, and then the coil packs.

make sure your gas cap is on tight Ive had this problem before and its was after I put gas in.

So I checked my owners manuel under troubleshooting panel lights. This should correct the problem.
