I see so many paying a lot of money to stop the egr from working .What would happen if you just blocked it off ? I am guessing the computer would freak out .
I was going down the highway with light traffic at 70 mph and decided to look at the gauge cluster readings in the dash .It was 88 degrees out . Coolant was at 206 , trans temp at 181 , oil temp at 219 , oil pressure at 40 psi . All at 2000 rpms . No load . Do these numbers look average...
