Check Engine

[Teodoro Rinconeno]

Check engine started flashing I counted 40 flashes as I was driving this is second time it happened. I have a 2017 Silverado 4 by 4 1500  approximately 99,200 miles so far no issues while driving .

Checking the logged code(s) would be your next step.

Code detected PO300 Random/
Multiple Cylinder Misfire. Will replacing spark plugs solve the issue .

That would be the easiest fix.

 

Probably a good idea to buy a new set of OEM plugs being that you are at nearly 100,000 miles.

 

Pull the plugs, inspect them, inspect the wires and see if you find any specific problems.

My daughter's '14 Cruze did the same thing at 135K miles.  Replacing the spark plugs fixed it, especially since one of them was cracked in two places, was shorting out to the block.

Replace the plugs with OEM is where I would start.

Yes, stick with the OE plugs.  It is well known on here that the original plugs perform the best.  Keep us posted.

Looks like RockAuto has a promotion on the OEM spark plugs and the price isn't bad either.
