I own a 1983 GL wagon, and have recently been having some problems with it bucking when trying to climb hills. I replaced the fuel filter and plugs. My dad seems to think it could be electrical, but I am convinced it is fuel related. The problem is some what sporadic, but guaranteed to happen on any hill. Having a full tank of gas seems to help, but it still happens from time to time with a full tank. Anyone experienced a similar problem? Thanks, wowzers.
