What year car and how many miles on it?

Yup. Get to the bottom of this before going on the spray. I suspect you may have some carbon build up. I would Sea Foam the sucker as it is a cheap, simple fix if it works. You also may have problems with your plugs or ignition system. If you are not getting a good spark, then you would get detonation too.

Answer my question up top and we will go from there.
