Hi I'm new, I tried searching for for this topic before posting but couldn't find anything. I apologize if this has been covered.
so a while back I was running short on cash and put 10 bucks of 87 grade fuel in my car and then I got the cel . I have since only ran premium in it and the light continues. I replaced the sensor even tho I knew that wouldn't fix the problem. I ran seafoam thru the gas tank, reset light and it comes back on. I don't really hear any pinging but I'm not exactly 100 percent sure what pinging sounds like. Watched a couple videos on I don'tpinging andi dont hear any pinging. The car is leaking oil but not alot and I stay on top of it. if it is low which has only gotten low once in the past 3 months, I top it off my next plan of attack is new plugs. This is my first k20. I have a **** ton of experience w d series motors. So I would say new plugs and wires but I don't see any wires lol. Any suggestions is appreciated. Thanks again.
