Question about 1999 Toyota Camry Solara
When driving the car it has a knocking sound coming from the engine and cuts off while I am driving...what could this be? It's a 99 Toyota Camry Solara
Meloe77, there's a high possibility you have a mechanical failure inside the engie causing the knocking sound. (Check the oil?)
The reason for shutting off is because the knock sensor can hear it, and the powertrain control module (PCM, herefore) is trying to detune the engine to eliminate the sound, (as if it were caused by bad gasoline.) The fact that there is a mechanical knocking sound, means that the sound cannot be eliminated by detuning of fuel or spark mapping, therefore it starves for fuel and/or spark causing the engine to stop running.
My recommendation: Have the vehicle TOWED to a reputable mechanic and ask him if its possible that I'm right.
