Greetings! My car has an intermittent problem, which is that when the engine is cold, under heavy acceleration with the air conditioning running, the engine will lose power and die. If I wait a few seconds then restart the engine. Everything is fine for the rest of the day. This is a 4AFE engine with California emissions.
In pursuit of fixing this problem I have replaced the following:
-Distributor, Spark plugs and Wires.
-Fuel pump, screen and fuel filter.
-Sub-diaphragm idle-up actuator.
My gut tells me the issue is somewhere in the vacuum system, perhaps a sticking valve switch (VSV) or maybe something with the EGR system.
Other than this annoying issue, the car runs great. I really want to get it sorted out for my peace of mind. Any input is appreciated! Thanks for reading.
