Camry intermittently will not start
I have a 2000 Camry(v4) and usually drive it on local roads. Lately I found that if I drive my car to highway(for around 10 miles), the next day the engine won't start. It has happened 4 times in 2 months. When it happens, I need to step on the gas paddle when starting the engine and then it would start. After that if I try again(without stepping on gas peddle) it would start without problem until next time I drive it to highway. I have done fuel injection, oil change, battery replacement but it still happens intermittently. A local repair store checked the spark plug and said it's not spark plug's problem. I cannot always reproduce the issue and the repair stores can do nothing about it. Any idea? Thanks
