On my way to work yesterday my usually reliable yota started acting odd. The car has very little power almost feels like I am running on 2 cylinders. The 7afe literally sounds like a subaru wrx box engine. As I am accelerating the engine feels like its working fine then drops in power then jumps in power. It died on me and woulnt start up so i pushed it into a parking spot on my way home from work.

Sounded like a combustion problem to me so i got some new spark plugs replaced them. The engine started up but limped home. The old spark plugs looked like i was running rich, lotta carbon, but not too bad. The weirdest part is that the check engine light is not on.

There is spark on all four wires and i wasnt reving the engine very high the last couple of days.
Im stumped and dont really want to take it in to the shop. N E ideas? Injectors, destributor, timing belt???

Any help would be appreciated ,

did you change the plug wires as well, that happened to me and the wires made the difference

this sounds like a coil going bad. I would take a voltameter to the coil and see if its getting proper resistance. Usually they can get you home, but I wouldn't count on getting you there.

Good news....

Changed out the plugs and the car is tip top again. The wires looked fine but one must have been bad. Nice little tune up, 50 bucks later, and its all good. Thanx Guys

I thought you changed the plugs the first time?
