I have a 1998 ford windstar, 3.8 liter v-6 with 201,000 miles on it. I took it to get an inspection and it failed because the check engine light " DID NOT" come on when the key was turned in the ignition with all of the other lights that light up when the key is turned. The tech said the 02 sensors and egr valve were at fault for this. I replaced the 02 sensors and egr valve, pcv valve, some broken vaccum lines and air filter. After replacing the sensors he specified, the light still doesn't light up when you turn the ignition key. The engine also kind of stumbles or chugs repeatedly throughout the rpm range above idle when the throttle is held. Also when you turn the heat setting to upper vents and floor vents and it's idling, the engine surges about every 4 seconds. Please help. Thank you.
