I own a 2005 Ranger 3.0 Edge with a freshly installed K&N Cold Air Intake. For the first time since I purchased the vehicle in 2007 a warning light has illuminated. Its either the "Check Engine" or "Exhaust System" light; in the manual they both share the same symbol. The light turned on after a hard acceleration after start up - the engine was previously running for awhile, turned it off for about 5 minutes, then turned back on and hit it..very dumb move I know.. frustration got the best of me
I let the engine cool off for a couple hours and still the light turns on. The MAF sensor looks to be fine, and yes I did check to see if the gas cap is tight
I plan to disconnect the battery tomorrow to see if it switches off, it not run OBD II. Any ideas what I've done?? Oh and if your wondering, i only have 19 000 km on it.
Thanks for your time!
