Need more help with ICV removal
1990 535i auto, intermittent starting problem, idle issue surging slightly. The problem appeared suddenly, always starts but sometimes needs extra gas, seems to go away when warmed up. Most prevalent when idling in park, although does try and stall out at stoplight occasionally. Idle low at 500rpm.
Had a half hearted attempt at pulling it out (the ICV) this afternoon, but other then busting the tab off the rubber bracket holding the ICV in place, I had zero success in removing the hoses etc... Was afraid to bust something else.
Does the rubber boot - #8 that the ICV's connected to, have to come off as well, and if so, how do you get enough clearance to pull it away from it's fitting to #1 and it's connection on the opposite end?
Or does the ICV slip out of the boot - #8, after removing the connection #10 running out the bottom of the ICV? And if so, how the heck do you get that little hose off it's connection with the ICV?
Like I said, I unplugged the ICV and cleaned the plug as best I could. Broke the rubber tab off the bracket #18, but had no success actually removing the ICV #17.
Any and all suggestions welcome. I've got a date with a money sucking mechanic shortly, and I will replace the fuel filter and likely the air filter tomorrow, but I'd like to narrow the search somewhat, if not solve it, before turning it over to the man.
