I have a 1986 Dodge 600 convertible with a 2.5 Ltr. engine with
109,000 miles on it. It is terrible on gas and runs very rough. As I am driving along it seems to surge and sometimes seems to have a dead spot happening. This happens if the car is warmed up or not however it happens more frequently when it is warm. I have had a new exhaust system including catalytic converter, wires, distributor, cap & rotor, plugs, fuel filter, head gasket (couple years ago) timing belt (couple years ago) and fuel injector serviced in 2000. The scan test showed that there was a problem with the distributor so I had that replaced but it shows everything else is fine. It obviously isn't and I am wondering what else could it be? Is there a way to tell if there is a malfunction with the car's computer or a leak in a hose somewhere. Any help would be appreciated as I just can't afford to keep taking it to the garage for a game of hit & miss. Thanks. Blondie
