I'm having a strange problem w/my 92 Honda wagon. When it's hot outside it won't start. When it's cooler - early morning or late at night, it starts fine. When it's hot - not when the engine is hot - but rather when the ambient air temp is hot, the engine cranks fine, but just won't fire.

The car is a 92 LX wagon, with 227,000 miles. All original. Other than the starting problem, it runs fine. Only other issue is that it idles a little roughly at times.

I'm a Honda novice and have no clue what may be causing this starting problem. Any ideas out there?

THANKS!
