I am new to the Bimmer Community and I am happy to have found this group. My '94 530i has been great until last Sunday when the Check Engine light came on and the car started to lose power. I took it to my mechanic who has cleaned the fuel line and checked the transmission. I got the car back yesterday. After I got gas and drove away, she backfired and jerked. I immediately took her to the BMW specialist that my mechanic suggested. Has anyone experienced this? Thanks.
