1972 to 1993 model year American Motors (AMC) vehicles equipped with a carbureted 304, 360, or 401 cubic inch displacement engine.	The Throttle Body Fuel Injection Kit, Model No. JP-V8, includes the following main components: Two barrel General Motors (GM) throttlebody with integral throttle position sensor and idle air controller, Open Element Air Cleaner, Electronic Control Module (ECM GM P/N 1227747), wiring harness, MAP sensor, engine coolant sensor, heated oxygen sensor, electronic fuel pump, fuel filter, fuel pump relay, and vehicle speed sensor. Ignition timing is set at 6-8 degrees BTDC at idle. No changes are made to the stock carbon canister except for the vacuum line that was connected to the carburetor float bowl vent; it is plugged at the canister. The new heated oxygen sensor is installed in the stock location on vehicles currently equipped with an oxygen sensor. On vehicles, which do not have an oxygen sensor, the sensor must be placed 3 inches down stream of the exhaust manifold flange. The installation of the kit requires the removal of the following components that are located within the engine compartment: Air cleaner assembly with heat stove, idle solenoid vacuum line, transmission controlled spark solenoid, distributor CTO vacuum control, carburetor/throttle body, fuel pump, ECM, oxygen sensor, air injection system (air tubes plugged), and other related vacuum valves and lines.
