Did you do all the wiring required for the 1G CAS to work properly without throwing a code? Also, is it a 95 or a 97-99? the Wiring is different depending on year, the CAS signals are inverted. If you have conflicting signals between the Cam angle sensor and Crank angle sensor the ECU will be very confused and could possibly be the problem. Usually that will throw a code though. Also unless you have DSMlink or AEM the MAP sensor still has to be there. The "bolt" you are missing isn't actually a bolt, a TPS open/closed switch goes there, on a 1G.
