4.3 liter s10
Trucks been having a little trouble running went to
a garage they told me it was the EGR valve so I
changed it out and it was not the problem. Going
down the road it jumps a lot and will barely get
over 35 to 40 miles an hour I can park it put it back
in Drive hold my foot on the brake and it won't even
clear 1500 RPM need some ideas of what it could
possibly be
