Idling problems mixed with possible electrical problems.

[dreamriser]

I just bought a 89 - 325i about a week ago, I've been having some major idling problems, the air intake hose cracks,so I know that's a big part of the problem,so I put some duct tape on it for the time being (I've ordered the hose). However yesterday the car started missing on a whole nother level,this time the hazard lights came on and I didn't turn them on.I stopped and hit the idle control valve a couple times then the vehicle calmed down and barely brought me home. So can someone tell me the possible causes of this recent bad stuttering and what can be done to sort it out,thanks in advance.

You have an electrical fault buddy...
The turn signal issue is completely different from idling !!
REMOVE the ICV and the Throttle-Body and clean them thoroughly, RETRY...
Let me know the results?

Thanks for the help Dabsy , I cleaned the throttle body and the ICV, I even took off the intake hose and put some more duct tape on,I then turned on the engine,the engine is runs a lil better but I still have the missing problem, I took the vehicle on the road to see if it would run better,but there's still a serious problem cause it jerks you repeatedly especially when in first and second gear and whenever it misses there's a warning light that flashes at the bottom of the dash,this warning light is green and looks like the hazard light symbol,what could this mean ?
