All lights illuminating after the battery light came on and 45 mins late no steering no acceleration and finally no power!!! Not fixed because no one will give me any answers aside from taking advantage of me because I'm a female and I've been told everything from the serpentine belt to the crankshaft pulley to the voltage regulator and the alternator then the timing belt!
My check engine light comes on whenever I start the car and begin to drive right away. I think it's reset after a few times of starting the engine and letting it sit for a few minutes letting the idle drop to normal before beginning to drive or even touching the gas pedal. Sometimes it's worse than others, like when the idle keeps going up and down when I am stopped at a light or something and also has stalled when I come to a stop and the idle falls too low. It's not a good fix because it keeps happening and I now have 190,000 miles on my car.
Scion suddenly stalled 1 day while coming to a stop since then my check engine light has stayed on even after cleared. when hooked up to a scanner three diff. evap codes come up. I've also replaced my gas cap but still idles rough other than the first start of the day. Usually dies when I come to a stop or after starting it again after it has been driven prior too. I was told it could b iac valve but dnt think my car has one of those. No solutions or answers yet
