1990 740 8 valve 2.4 Bosch

Car still idles great but no go when you step on the throttle. Replaced the AMM and IAC due to codes from the computer. Replaced both fuel pumps and filter.

All four spark plugs are badly carbon fouled. I am rebuilding the injectors, replacing the spark plugs this weekend. I am going to replace the distributor cap and rotor also. Maybe the coil.

I rebuild as a hobby SB Fords so I am not a total dummy. My experience tells me that the spark is too cold. What exactly does the power stage module do??? Is it an ignition module. Does it amplify the spark?

The dumb book I have does not answer these questions. Is the coil 12v or use a resistor to use less???

Thank you!!
