Engine stumble & blower fan motor
Not really an issue rught now, but when I get it back on the road.
I noticed that when ever I turned the blower motor on, for defrost or manual fan switch operation, the engine wold start to stumble/sputter some. I did unhook the fan relay & am using it as my fuel pump relay. Could this be the culprit? does teh fan realy have anything to do w/the blower motor or is the blower motor drawing too much juice thru the circuit? Haven't seen the schematic on it yet, just wondering at work

Check to see that your EFI harness isn't running too close to the blower motor. Could also be that the blower motor is starting to fail. The brushes/commutator is arcing which interferes with the ECM.
