I just loaded a new 3.0 engine in a mazda mpv and I can only make it run on three cyl. The passengers side is dead. It is almost like it is out of time but I know that it is not for I have changed the timing belt and distributor. I have spark, fuel. air, and compression check was good. Also the valve cover was pulled the cam is working. I am puzzled I don't know what else to do..Other firing orders and rotor cap wiring is very welcome. The last engine poped a rod and still ran when I took it out.
Oh I almost forgot the check engine light comes on along with the ALT light and A/T Oil Temp Light. The thing will sit there and run but only on 2 4 and 6.
 
I think it's the computer. Mine did the exact same thing (same year too) and I ended up leaving it on the side of the road. What mine did right before it died and wouldn't start back up is red lined, all the gauges spiked, and I never saw it again.
