I have a 1995 Avalon.
Generally, it runs very well. The original alternator went out last summer @ 121K miles. I replaced it and also put in new plugs. This car starts immediately on the first try when first started in the morning. But after that it often struggles to start the rest of the day, I need to crank and turn the key off usually 3 times. It then starts. What could be causing this?
