I have a 94 Exp with 107K miles...it has been a great vehicle...no major problems what-so-ever. Lately I've been getting a lot of pinging from the engine when I accelerate. The harder the accel, the more pinging I get. I also notice that when the engine is at idle, it chugs a little....like it can't "breathe". Nothing major but certainly not the norm.

I am clearly not very auto-repair savvy, but I know enough to find my way under the hood. Can anyone give me some pointers as to what may be happening?

I appreciate any suggestions that you may have to offer!!
