Well, needless to say the shop I chose put the engine in and did everything, problem is, the check engine light comes on when I'm off the throttle of almost off it, at any speed, on the highway or going 25 down a backroad. When they hook up a diagnostics machine the light does not throw a code. What is this??????
Also the car has an issue starting. It takes it a good 15-30 seconds of cranking before the engine will fire. They have been through the wiring completely at least once since the install, have checked the distributor and as far as I know all of the sensors.

other info: 92 accord, formerly auto, converted to manual, OBD 1 JDM H22

please help...
