1984 - Stalls with heavy throttle
If I’m light on the gas, it’ll accelerate fine, and I can even get it to shift into second. But if I’m driving like this and give it half throttle or more, it just cuts off, as shown in vid
-It revs fine in neutral
-No CEL
Long tubes are installed, o2 sensor isn’t installed. Whether the missing o2 sensor could cause this or not I don’t know.
Fuel pump, fuel filter, distributor, spark plugs, and plug wires have all been done recently.
Also, does the engine sound like it’s running fine? The long tube headers are open and have nothing connected to them.
