'94 2.3 with bad mis and heavy pinging
Just wondering if there is any one thing that I should be looking at on this 2.3. It has a bad mis, and anytime its under a load it pings really badly.
I just picked this truck up the other day, so I haven't had time to do my own compression test, but the PO stated that one of the cylinders was low, and all increased about 10 - 15 psi when wet tested. (about normal)
Anyway, the engine doesn't smoke, or knock, and other than the pinging, and the mis, it sounds really good.
I'll be pulling the head over the weekend if I can find the time, but I was hoping someone might know what I should expect to find.
Thanks for any input.
