dieseling on acceleration

Jun 24, 2005 Last reply: 21 years ago 2 Replies

I have a 97 Ranger and I am getting a dieseling sound when I step on the gas. This happens when I am coasting along in a gear that may be slightly too high for the current speed. I get the sound briefly then it goes away. I switched to mid-grade gas from regular and it helps some but it still happens. Any ideas? TIA Tom


Old or improperly gapped plugs, carbon build-up or improper timing.

AFAIK, it just started in the last 6 months.
