prince george,
my eclipse misses and won't rev up at all and stall once the engine is warmed up real well. this takes about 15 minutes. then it will ack like it is not getting gas, the rpm keeps dropping down and it is undriveable. once the engine is cool your good to go again till it warms up...I have checked out the idle module, the fuel pump, and the air flow module and all this is good....i think it might be the ignition module but no one here in the north has any way of testing these cars....I am trying to find a test procedure i can do to test the ignition module...........................the car is a non turbo 1.8 litre mitsubishi eclipse..
 
The best ignition test is to pull each plug one at a time, ground or clamp it against the engine, reconnect the spark plug wire, and have someone crank it over and watch the spark between the electrodes to if it is strong, weak, or not present. This tests everything at once. Also watch to see if any spark is jumping from anywhere else where it shouldn't be (eg. wires, coil, etc.). If the plugs are wet when you first take them out, your ECU temp sensor (not the temp gauge sensor) may be bad misleading the ECU to think the engine is always cold so it enriches the mixture.
