Check dist. cap and rotor and replace. Just fixed one last week. Rotor was causing a misfire under load and coil contact to rotor was worn out down too the cap. Graphite dust from the center contact in cap was all over the rotor causing a misfire. $25.00 in parts or less. While you are there replace wires and plugs. Autolite ap25 plugs 2.99 each

Engine shuts off while setting at idle.


Pumping the accelerator on a fuel injected car is usually a worthless exercise--the technique works on carbureted cars with accelerator pumps. But in your case, it may be helping a bad throttle position sensor make some idle contacts come together. the throttle position sensor has a variable resistor to tell the engine computer where the throttle opening is--and a switch to tell the computer if the throttle is open or closed as at idle. This sensor isn't cheap so I would buy a Haynes manual to help you check it out before replacing it. Some auto parts stores will "read your diagnostic trouble codes or DTC's" for free. Even if your check engine light is not on, some transitory codes can get latched in memory and help you solve the problem.

Short the test terminal, and read blinking engine light blinks, count them they will be fast and pause and be fast again each code is 2 digits long. This will help me to solve your problem. Thanks
