Excellent video. I have this problem on my 2001 Ford Escape. My car is stalling at cold start, the exhaust shaking and after engine warms up it stops shaking. Question I replaced the egr and car would not start I got it to run after several attempts while stepping on gass then I replaced dpfe sensor. the solenoid I’m thinking I might have to replace too I took the hose from top of egr, while car was turned on and put my finger on hose I feel a suction on finger is that a good indicator that solenoid is good? The other solenoid I replaced did not have a suction after removing hose from egr.
