Acceleration pinging with 2000 ranger 2.5l
I am new around here and need some help.
I have a 2000 ranger 5 speed with 2.5l engine. It runs fine in cool weather and when the engine is cool. After and warms up and worse when the weather starts getting warm, I get heavy pinging during acceleration and rough idle. No trouble codes, no check engine light, no overheating. Could this be an EGR issue or something deeper?
