So guys I have a 89 Ef with the B2. Never had a issue out of her with 180 on clock. She started missfiring otw to work one morning so I got to work parked it for the day and the rest is history. Would not crank for anything after that. I threw new plugs,cap/rotor,2 dizzys,3 ecu's,2 injectors finally got it to run for a min or 2 and the whole time it's high revd and dumping smoke out the exhaust and seemed like there was an oily/fuel mixture soaking the pavement. Keep in mind this been over a year ago so my memory is a little faded but she's still sitting in the shop now. Well I'm wanting to get it back up and going. I do not wanna do a crazy swap or anything actually I really wanted to just buy a reman B2 in obd0 to drop back in plug n play since I don't have very much free time to do anything extensive since I work out of town/state 90% of the year and it's gonna be my little commute car again. So really my question would be what do y'all think the easiest option to pursue. Striping it down and doing full rebuild then converting later on to mpfi. Which would be the easiest d series to drop in since obviously you cannot find a decent B2 that's plug and play under $1500 hell I'm seeing them high as $2700. Why?!
