Greetings everyone. My 85 B250 318 runs like a champ when cold . As it warms up, it begins to ping when I want to accelerate. When it's hot and I shut down, the engine diesels. It won't when it's cold. I changed out the ecu with a mopar performance orange ecu. The problem now is not so severe, but still persists. The distributor vacuum advance diaphram is good and holding on my vacuum guage. Anyone experience this before ? Motor has 142000 on it and I run shell regular gas always.. Thanks.
