87 Superliner surges constantly down the road.
Super Liberty replied to Super Liberty's topic in Introduction Forum
We changed all the fuel filters, and changed the fuel lines and thought we cured the surging. 200 miles later it was back. The injection pump has approximately 100,000 miles. Changed the harmonic balancer because it looked like it was leaking.... We just noticed air bubbles in radiator, but not overheating and we tested for the head gasket with the bottle off of the overfill line, and it looked fine, but there is pressure in the radiator. The truck has more power than it ever has had before in the higher RPMS. When you are in lower RPMS the truck surges so bad it is almost not driveable. We appreciate any input. -
Hey Yall, wondering if you could help us? We have an 87 Liberty Superliner with a 350 Mack that has started giving us problems with surging while you drive it down the road. We thought that we would change the fuel lines that look old which were a braided line with reusable fittings. They still hold pressure, but thought we would change them anyway. Cannot find braided fuel lines except for stainless steel, which I am not wanting to use them. Any ideas?
