FD weird electrical problem
 
Hello! :) Having some problems with the FD. Just got done replacing a leaky fuel dampener and did the silicone vaccuum tubes. car ran for three days, smooth as butter, coming back from Sevenstock when the car just started to fall on it's face whenever it was given gas, limped home thinking the fuel sender took a dump and ran out of gas, got gas then found out that it would start, idle, and rev perfect.

Whenever engine is under load it sputters or stalls, whenever the brake pedal is depressed the lights dim or it just stalls, I have 14 volts at the battery when running and voltage only drops to 13 right before it stalls because the belt is slowing down. I put 12v @ 200 amps with a battery charger and the car wouldn't stall pressing the brake pedal, but the lights would still dim, and still ran like poo when engine was under load.

Any help would be much appreaciated, thanks! :)

Found it! Engine ground strap had lazy connector, just gave it a little wiggle. :wiggle: Little wire = big issues, WOW!

Glad you found it. If the ground disrupts the signal to something important like, say, the ECTS, yes you will see very noticeable symptoms.
