My van has never run hot. The guage has always shown near cold, and the heater has given just enough heat to get by. The engine runs fine, and fuel economy is fine. We're moving north, so I just installed a 192 degree thermostat,(to replace 180 degree), and had a flush and fill done @ a reputable shop. The guage shows warmer, so logically the heater should blow warmer. Once in a while it's warm, but usually it's lukewarm, just enough to keep the windshield clear. HOW CAN I GET DECENT HEAT?? Could my heater core be going? Rob

I have a 96 Chrysler T & C van with the 3.8 liter V6 and 158K on it. A few weeks ago, the EGR valve went south and I had it replaced. The van has a lot of miles on it as you can see, but has been well maintained since I bought it at 50K. I put a lot of highway miles on it, primarily. Today the CEL came on and I stopped at a parts shop for a scan. It showed PO171 which I believe is a lean condition (Bank 1) picked up by the O2 sensor. The van runs fine with no hesitation or driveability problems. [B]One thing noted since the EGR valve repair is that the van is difficult to start after sitting all night.[/B] A new fuel pump was installed about 6 months ago and a tune up shortly after that. Any ideas what may be causing this? What process should I use to troubleshoot the cause? Any help will be greatly appreciated.
