Car is an 1/89 production 325i vert.
I've had this car awhile now and despite having done quite a bit of work, never did sort this issue out...
Whenever it starts, hot or cold out, just ran for an hour or sat for a weekend, it takes 5-10 cranks to start up instead of just 2-3 like other e30's I've had. -Sometimes- it doesn't start on the first try, only to start right up on the second go. This went away 90% after I cleaned the c101. When it's really cold out there is some missing around 2k for a few seconds, then it seems to clean up. It is usually worse when it is wet outside. Just pulled the plugs and they were all dark tan. Compression test showed 165psi +-5 on all cylinders. I am wondering about the cold start system. I have checked for vacuum leaks and all good. Sometimes when it is wet out it will stumble under heavy load. The exhaust can be quite burbly at times. I posted a couple videos to help demonstrate. They are available in HD to hear better.
I have:
Cleaned/dielectric greased c101
New plugs, wires, cap, rotor
New injectors/o-rings
New FPR
New coolant temp sensor
What can I do to isolate this issue?
Thanks in advance.
