Reason I ask is my truck is still running like a pig after changing temp switch and o2 sensors. I'm heavily considering a 4bbl. The aftermarket intakes I've looked at have no crossover. I want to make sure I don't hurt the motor
I am going out there!! do you see a catalytic converter on your exhaust ?
if so I would bet 10 to 1 it is plugged up and needs to be replaced :coffee2:
One night my son drove up the hill in his 86 dodge truck 3/4 tun and I could
see the thing glowing red, he removed it and it ran much MUCH better, faster and mpg went up.
