My 89 was getting horrible mileage, rough idle, stumble off idle, etc.
New plugs, wires, cap, rotor, fuel filter, o2 sensor, cleaned throttle body, sea foamed it, set TPS, no dead spots found, etc.etc.
No change and getting 11 mpg. Has gotten over 20 before.
Checked manifold air temp sensor, open.
Checked crank sensor, open.
checked coolant temp sensor, open.
WTF. Hows this thing even run?
Voltage at MAP sensor seemed ok.
