I have come to the conclusion thatr my 1983 245 b21ft gets pretty lousy mileage at about 16 to the us gallon. Here's what I have done so far: new engine wiring harness new plugs, cap and rotor new catalytic conevrter new 02 sensor replaced all the vac lines replaced vac delay valve I tried spraying some wd 40 around the injectors to see it they were leaking, I unplugged the cold start valve to see if was running all the time. I have found the coolant temp sensor and idle air motor are shot and have new on order, but I don't think this is the problem. So... Maybe check the control pressure (really, I mean get it checked) but I'm wondering if there are some other items I can check myself before I take it to the shop?
