Hey i got a 91 stealth es automatic DOHC had it on the road since about late april and a couple weeks ago i went to start it to go to work in the morning and it wouldnt start i kept trying it finally started. Then it started doing it every morning except it wouldny start and when i got home from work it would start beautifully. And later in the day like 6 7 oclock if i let it sit for hour or two it wouldnt start until later the next morning.Then it stopped acting up for a while and would start when ever. Now its back to doing it again. Any ideas why it could be doin this? Check engine light comes on and off. Idles a little high when first starts up. Electrical problem? Sensor? Fuel issue?

 

My bet is the caps in the ECU have gone bad.

 

try hi test gas and can of dry gas
