Hi, my Miata is a 1995 with 1.8 engine and 95,000 miles. Latest a jingling song came from the engine when I accelerate it, I change from 91 to 95 gasoline in order to increase the octane but the jingling doesn't go .
Any help will be appreciated
Thanks
Juan
Tough to say without seeing the car but start with checking heat shields on header and midpipe for broken tack welds as they will make a lot of noise if loose.
