My '90 dx has been giving me some problems lately. Its really dependable, however sometimes when I go to start it, it will immediately die and will have a hard time starting back up. Before it would die then start right back up and idle fine, now it takes quite a few cranks to get it to start. When it does start it does seem fairly healthy with the exception to a low idle after it warms up. Someone told me it could be the main relay. However, sometimes it will start up no problem on the first crank. What could this be? TIA.

Also, does anyone know what the low idle after it warms up could be?

 

my ef did exactly the same thing, it def. sounds like the main fuel relay. at least it's an easy fix.

 

I had an eclipse that did that, i thought it was the cold crank sensor, but it was actually my distributor.

 

Dang my DX did that too but when it finally started it would sound like its running on two cylinders, then if I revved it up a little it would go away. I hope you find out whats wrong
