i have a 1991 truck, SOHC and carbed (isuzu if it matters) and the check engine light comes on intermitantly when driving. the idle is also sputtery and sounds a lil unhealthy. sometimes it struggles to start, but has never not done so. After i get it up and warm, these problems generally go away.

i need to go find out why the check engine light is on, but does anybody have any theories?

edit: carb was recently replaced so it is not that, anything else it could be.
