EGR FLOW Sensor issue
I saw a post on the TL egr flow sensor issue. I have the same problem on a 97 3.5RL.(Code P0401-low flow) Unfortunately I got the warranty extension notice, but have 168K on her so no dice for a dealer repair. I pulled the EGR, cleaned it and removed the EGR to exhaust port tube and cleaned it. I sprayed about a 1/2 can carb cleaner down the intake, but the light came back on again . I manually moved the EGR while engine was running and she started to choke, so I think the valve is working. Suggestions? Dealer said the warranty work could include wires/tuneup up to pulling the intake manifold and cleaning. Not sure what the real issue is. Replace EGR valve? Do tuneup? Pull manifold?

I reset the light a few times and it still comes back on. I figured its cheaper to pull the intake and clean versus $200 bills for the EGR valve. I was just wondering if thats the more likely problem as its EASY to replace the EGR valve.
