Have a stumble at a steady speed like twenty five to thirty mph. I already changed EGR valve and pressure feedback sensor and hoses.

See attached picture and check items listed. Also, check to see if vacuum leak to EGR as well as partially blocked by buildup so try to clean up inside tube.

Took throttle body off and egr and looked for build up but wasn't any. Only thing I haven't changed is the egr solenoid. Don't have a vacuum pump to check for leaks

Start engine and use choke cleaner to find a leak other than hoses if rpm changes you found it
