    My car turn on the engine light when the gas cap is loose. I had to change the cap and the light turn off about 2 weeks later. Now I had the same problem... I check the gas cap again... it looks good.. but the light still on. Don't know what to do now...

    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

    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!

    dash lights have been on for quite some time. Had a mechanic look at it and was told the camshaft gear assembly needs to be replaced at about $700.00.
