Well, the car just rolled over to 107k on the way home from work last night. And its right after midnight, no cops, no other drivers, so I decided what the heck and Stop and get dinner and then do some burnouts in an enpty parking lot. Well I noticed the car started pinging at WOT. Now correct me if I'm wrong, but the problems could be a dirty Fuel Filter, Check plugs(white color means lean), Check MAF/clean it(my maf is fine, if I unplug it, the car wont idle, plugit back in car runs fine) Possibly a clogged Injector?
I'll pick up a fuel filter and some new plugs(22c Motorcraft)and some seafoam/injector cleaner, tomorrow, and also try running 89/93. This started right after I pulled the sct chip...(pulled it to test in a friends car, havent put it back in mine yet)
So other than what I mentioned, is there anything else I should check on?
