I have a surge sound in idle.Its a up and down sound.Do u know what it is?
Whenever it surge in idle it runs like that when I drive.It runs like its stopped up.It jerks like it loosing power.But this doesn't happen everyday.Sparkplugs,wires,rotor button,fuel filter,fuel pump,vacuum hoses have all been change.The computer had a code of 13,14,15.But I dont have a book.No mechanic has figured it out.I have 233,000 miles.HELP!
