So I bought my 95 7 months ago. It was the essential basket case, however I've fixed most of the worst parts. The only thing left is to solve the very very bad MPG. The car runs very strong, actually stronger then it should almost. I pulled codes, got EGR (there is no valve, just a block off plate), and a TPS sensor to high voltage, set screw to low for throttle, and ISC not responding correctly. The car even when running bad would just burn the tires off of it and run great up top, however idle problems and bad MPG plague it seriously. I've replaced all of these
New reman distributor
Ford racing wires
New cap and rotor
new NGK plugs
New motorcraft IAC
New cold air kit (the stock stuff was toast and leaking badly)
Alot of new vacuum lines
New ECT sensor
Long tube headers etc.
Theres a couple other things. I havent replaced the fuel filter yet, the car hasn't seemed like it needed one, never had a lack of fuel. However it only gets around 10mpg, and it doesn't matter how I drive it. I put a new IAC on it today as I work at a ford dealership and got it for cost, and most of my idle problems went away, however I don't think everythings gone. It will sit there and pur at idle, albeit a little high at first so i adjusted the set screw and IAC percentage via the allen head screw on the TB, and got it to idle like I wanted. The CEL is not on, but it will idle perfectly fine, no surging after the IAC install, yet it will suddenly make what sounds like 2 puffs of a bad exhaust leak and stumble slightly but catch itself and be fine. It's very odd, and I do know that the pieced passenger side header has a leak at one of the connections, So I plan to weld it up. Today I also installed the NGK plugs, and I pulled out the old set of autolite 24's someone previously put in it, and they were white as a ghost. The car is running ultra lean, but doesn't burn a drop of oil. The Plug has no smell of gas or oil, there is frankly no smell at all. I'm not sure what it is, it runs great up top but this mileage thing is killing me. I don't know what it is thats causing it. Brakes are not dragging, I installed new Ford OEM front hubs even and had the rotors turned. The rear is free, albeit a little wore out. Any suggestions would be appreciated, I'd like to get this maintenance out of the way so I can go on to installing my 3.73, axles, girdle, and trickflow heads
