Hello Scotty, I have a 1999 Toyota Solara with 254130 miles with an automatic transmission. The car does not accelerate and can not go up hill anymore. I can't get out of my own way anymore. When I step on the gas too hard or fast the speedo does not move but rpm needle does. I have code P0303. I have replaced spark plugs, Igniter, o2 sensor, charcoal canister, air filter, and gas cap. I'm thinking it's something electrical? i don't want to put any more money any more unless it's a easy cheap fix. Should I just sell it to a junkyard? Is it worth fixing?
First swap the #3 ignition coil with another one and see if the code moves to that cylinder. But mileage and age are strong reasons to get another as it sounds like you may have trans issues too... but again, swapping coils is free and a coil pack may solve it (estimate 15% chance).
