My scanner is an SPX/OTC ScanPro #3409. I have access to my buddies Snap On, with all his expensive updates, but this unit fits my needs for as little as I have need for it.
I finally cured the code P0172 problem. It's almost embarassing how simple it was. I found a vacuum cap off. It's hard to believe one small 1/8" leak constantly caused the code, but there are no set, or pending, codes after 1,000 miles. Before, it would go 30 to 50 miles around town and 100 and 200 miles on the highway before setting a code.
