so i got this code P0300 random/multiple cylinder misfire...this is my opti right? cuz i had that replaced less than a year ago and ill be pisssed if it is.....
thought it was the fuel pump...i was wrong

 

Could be anything.... when they scanned it, did they check the misfire counts on the indivirual cylinders? That will tell you if its a truely random misfire, or mainly only one or two cylinders.

 

no i scanned it myself.....i barrowed one of those scanners they have at autozone.....i was just looking to c the code.....i didnt know u can check which cylinders are misfiring if u could?

heres the deal tho....i have new coil/ICM, opti is less than a year old but is still not counted out....plugs and wires i dunno prolly origional.......
it seems to only happen when teh car is warmed up and u go for a drive...turn the car off come back to it and start it up again.....then it misfires....only recently it decided it didnt want to run...the misfire went on for a like a month b4 i got a code...and i know optis are notorious for not spitting out code for a while..

well thi time im not taking it to dealer to get it checked out cuz i was raped once b4 for that opti....i know a few ppl that will help me out.....soo ill c what they will say.

just wondering what u guys thought

 

I think my car is faster than yours..

 

If you don't know about the age of the plugs and wires, change them.

 

hehe dipshiot......

i have new plugs an wire....ill fond out y i have a mifire..if thats the problem ill get em changed
yet again illlook for arching tonight

 

so were their any symptoms and how did you fix it, I had the same code show up on me today, car seems to be running fine though.

 

car will bog down,,studder, then go, stall ,run rough,, etc .........but not all the time......car seems to run fine......but when it warms up and u shut it off.....and start it back up it goes crazy
no i javent fixed the problem yet......i had to go out for a family b-day party...ao i didnt have time to get to it
