Pinging Noise 2.5L
Hey guys, I have a question for anyone who knows the answer to my problem. I have an 01 Ranger with the 2.5L engine. I have always noticed that when driving my ranger, a pinging noise starts mostly going up hill but also when accelerating. I've never noticed any decrease in power when this occurs nor does it seem to put any wear on anything. I could roll the windows down and turn the radio up but it doesn't solve the problem. It has 93,xxx miles on it and its my daily driver. Original plugs. I replaced the paper air filter with an OEM Spectre High Flow and I gained power and with this power gain the noise seems to occur more. Any help is greatly appreciated. Thanks.
