engine light? my 98 toyota avalon has check engine light. When i starts the engine in the morning it runs smooth on park but as soon as i am putting it on to drive the engine starts misfiring, it will hesitate and vibrate for few minutes and then after some times it runs great. Pulled out codes - says cylinder 1,3,5 & 6 are misfiring and codes for coolent temprature and fuel sensor. My close car mechanic said me that it might be bad computer as car runs great after first run. Please help me out with problem..
