A few weeks ago my car pulled a p1400 code mdp sensor curcuit. I replaced my mdp sensor and cleaned my egr valve. Now my car after running for a few minutes, the rpm will drop to 100 to 200 RPM and the car is running really rich and when i hit the throttle it just bogs down. My car did this same thing before I replaced that sensor also. Im completely stumped, i checked all vacuum lines and they are good. ALso, i just installed a new evo3 16g and wideband. My old turbo went bad. Thanks.
