i have a 91 toyota 4runner, this started a few days ago, so far ive replaced the maf and no luck, it seems like its not running on all 6 cylinders, please help me out, what else could it be? tps? spark plugs? wires?


help help help

 

Start with pulling spark plug wires off 1 by 1 while it is idling. If you pull one off and have no change in the sound of the motor you have a dead cylinder. Next step will be to figure out why. Id do a compression test next on all cylinders and see what you got.
