Random misfire code po300?

[sleeperms6]

So last night my started my car and the check engine light came on. Took it to autozone aparently it was a p0300 I think, which was random/ multiple misfire. Car isrunning fine now but light is still on. Car has 46500 miles. Put injector cleaner hope it's that if not could it Bethesda plugs? If so what's recommended? I have an intake but plan on nodding more in the future. Thanks sorry for the long post

Did you check to see if the plugs were correctly? If so and everything is fine i believe it takes a few trips for that engine light to come off. If it doesn't turn off then there might be a problem still. I would say to try and clear the code at a auto parts store to see if it comes back on but that would be the last resort.

i think your brain had a couple random misfires while typing that up "Bethesda" and "nodding"

i'd check your plugs or a clean your maf sensor.

I've had really good luck with my Denso ITV22 plugs, but I may try those Bethesda plugs next time (my uncle used to live in Maryland!). Can I get them from SU?

Seriously, though, Cody and Bova are right. I had the P0300 about 20k miles ago. I purchased four ITV22s, gapped them to .030, installed them into my internal combustion engine device, and it has yet to return.

I got p0300 a couple of days ago, but that was after MAF pipe upgrade and I was running a bit lean. Adjusted the tune for new maf housing and the code was gone - all good now. I think I'm on ITV24s, whatever 2 step colder is.
