99 EGR problem.
I just recently replace an EGR valve on a 99 3.0 Ranger showing a code for low EGR flow. I cleared the code after replacing the EGR, and test drove the truck. About a day later the check engine light came back on. Again, it showed a low flow EGR code. I was wondering if their could possibly be something clogged in the intake, or the steel line going to the EGR causing this problem. The valve is an OE Ford part. The vacum line going to the EGR looks good, and has no leaks from what I can tell.(by visual inspection) I was hoping someone might have an idea on what the problem could be. Thanks.
