Just did a complete newly reman engine and tranny swap in my 93 runner. It started up and idled fine but a day later seems to be idling low and when slowing to turn into the store or neighborhood if you keep the clutch to the floor the rpm will just fall off and it dies. Any ideas?

 

Could be a timing issue if it wasnt rebuilt correctly. Have you checked/replaced your fuel filter? Could also be a vacuum problem?
