Daughter's Lebaron with 2.5L TBI. She noticed engine bogging down and hesitating when pulling away from a stop today. I drove the car and also noticed some hesitation at crusing speed around 40 mph, but no bogging as severe as what she described.
Pulled codes, and I see a 21 and a 32, for Oxygen sensor and EGR valve. I understand these symptoms match up to the O2 sensor possibility, but could the two codes be related? Also, she has not been driving car long enough for me to get a good idea as to her fuel mileage, and I know I need to check that.
If I am not mistaken, the egr code would result in rough idling on occasion, which also appears to be the case here.
