Why does my 1990 Cadillac Seville Backfire? - Yamaha Xv1100 Virago Xv 1100 1989-1998 Left Side Air Box Cover 1rm-14603-00

If I am not mistaken, it is under the rear seat bottom cushion.

its probably your alternator i would start by testing that im pretty sure advanced can test it for you. also test your battery because when the alternator goes it will run off of your battery and drain it if that doesnt work out for you then your going to have to provide me with further symptoms

Sounds like it is slightly out of timing or a valve needs adjusted.

does it have the chip in the key!!???if so the problem is in the ignition switch! there are two small orange wires that break off! on the coloum!

Most likley the instrument dimmer switch and that is part of the headlight switch, try wiggling it to get them on.

first get a gallon of degreaser like purple stuff from a parts store and clean throughly with a water hose. Be careful not to get the distrubitor too wet. then look for leack while on the groung

Replace ing. lock cylinder and key.

This is your firing order....

it depends, its caused by unburnt fuel lighting in the exhaust. it usually only happens at high revs

if it is a north star you nead a special socket the size of the pump you can rent one from some part stores
