I have recently had an episode with my 1995 Dodge Intrepid. I was getting an Insufficient EGR code. I went through the manual and checked everything and all checked out ok. I went through the and checked voltages and vaccume pressures and all checked ok, I took apart the EGR and tubes and examined, they were not clogged, but I cleaned anyway with Carb cleaner. Still problem existed. After a month of chasing this ghost, I took the car to the dealer. They told me that they put it on their computer and the computer showed that the valve was not opening fully. They replaced the valve and all is well. I guess the long and short of this post is that I have a decent code reader, the same one I used to borrow from the auto parts store, but is there a reader/scanner/software package out there that will allow me to look at this kind of data without breaking the bank? If so, what is a good one? How much can they monitor?
Thanks,
Dan
