4.9FWDfan Posted September 5, 2019 Report Share Posted September 5, 2019 (edited) Hi Everyone, New member here - contemplating buying my first Caddy (see title). I am a Ford guy going way back. Mustangs and Lincolns (Town Car and Mark vii). I have recently discovered the awesomeness of these FWD Cadillacs (up to '93) and now I want one! Better late than never I guess. I have test driven a 1991 ETC (what a cool car) and have some concerns. I have educated myself about the issues with fuel injectors (on the 4.9s) and other common problems with these drivetrains. Car starts up and runs ok, gets all gears - shifts smoothly but, when in gear, idling (drive or reverse) there is a slight jerkiness to the motion (foot not on the gas). Once accelerating you can't feel it. Once you get off the gas (now coasting) you can feel it again as you coast to a stop. It's almost like the brake was being pumped 2 or 3 times a second very lightly. Could this be fuel injectors (misfire)? Is there any way that the trans could produce this sensation? I have no problem doing injectors but I'm not looking to mess with tranny problems on day 1 with my "new" car. Mileage is 180 000 kms (112 000 miles). Very clean car in and out. Thanks!
