Quick History:
I have a 93 integra ls it was completely stock two weeks ago and it was beginning to back fire and would shut off and be a pain to start.

My dilemma:
I recently had a 93 ls head and block rebuilt from top to bottom... i swapped engines and after adjusting the idle the car will be standing still in neutral and will shut off... I could even be holding down the clutch in first gear and the engine will shutoff... theres no loss of power so I know it isnt the battery... anyone knowledgeable in this area with feed back please help me out. I just need a list of things to change that could be the cause for this problem. THANKS~!
