i dont own a mustang 2.3 but rather i have a 91 ranger with the efi 2.3L. i hope it is OK to ask these questions here.
when i run 87 octane the engine pings really bad. 90 it runs fine unless you are WOT up a hill. im not certain but im pretty sure this engine should beable to run regular gas, what should i check? i ran a full tank of injector cleaner in it allready. thanks for any help.
