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.

 

well run some seafoam through it and tune it up...you have carbon build up in your cylinders

 

I use a fuel additive, xp3, my dad sells it and its done a lot of good. I'll have to try that though. was trying to wait untill i hit 100k to do plugs. thanks for the help

 

What he said, seafoam and tune up.

Go for Motorcraft plugs.

 

IMO waiting to 100K to change plugs is stupid...i changed the plugs in my truck at 52K

 

2001 2.5L here and I experience the same thing. I have installed new plugs and wires, cleaned EGR (new gasket) and EGR tube. Have also ran techron in the gas tank, seafoam through the break booster and cleaned the MAF.

I also do not notice any power loss and the MIL isn't lit up (also nothing pending).

 

Could anyone tell me what 2 (or more) things make contact to cause this pinging noise?

 

I've had the same noise. It drives me nuts!
