1990 325i
Went from a died while driving to a crank no start. Did some searching and confirmed fuel, confirmed compression, spark was the issue. Doing some quick reading of things I can test/replace the coil came up. Figured it was a long shot because failure is rare. But, had an old coil on the shelf I knew was good. So swapped them this morning and bam! She’s running.
The idle is steady-ish. But coming off of a throttle blip in neutral she stumbles before catching and leveling. Also threw a new check engine code that was not present before 1222.
i did a smoke test as part of the checks for the crank/no-start and there aren’t any leaks. The injectors are new - and the AFM is a bavrestoration remanned. I have another one I can swap in (has a chewed up stud I can swap out). But what checks should be I looking for?
as a side note: if I hold the throttle at say 2k rpm the check engine will go away. O2 sensor, engine temp sensor, and FPR replaced in last 300 miles while I was doing valve job and injector replacement.
