So far I have replaced the Coils, Coolant temp sensor, Replaced the ICV, Cleaned the ICV, replaced the AFM, checked for vacuum leaks. I CAN NOT FIGURE THIS OUT!!

motor still pulls a coil 1 code 1271

The engine still hiccups, and bogs until completely warm

When REvving up the hose that is POST the ICV sucks in.

Like... it is collapsing? If this happens it will cause the car to bog. Common problem, you have to use still hosing, or use a plastic splice in the middle of the hose that will prevent it from collapsing.

Ohhh, so I have to put a little skeleton into the hose?

Well

put skeleton into hose, no more Hose Collapsing, however car still bogs.

"Recently Got a 1991 318is not to long ago." I just thought this statement was funny.

I thought recently and not to long ago were the same thing. Ha.
Thanks for the comedy Fiftytakedowns.

My 95 318is has similar cold start issues, along with some hesitation/surging/bucking in 1rst gear just off idle. My fuel mileage has decreased within the last year from mid to low 30's to barely 30mpgs now. I changed the air filter, fuel filter, spark plugs, oil & filter and belt very recently. I ran some fuel injector cleaner thru a full tank just before that.

I am going to try a coolant sensor, ICV cleaning and o2 sensor next. I really love my car and would love to get this fixed.

Im going to keep plugging away at it and keep checking this thread to see if anyone else has success and what fixed theirs...

Did you run checks on the coil harness/connector? I'd be tempted to run resistance & continuity check on that harness & the plug leads, but it sounds like a PITA.

Maybe the plug resistances too, while it's all apart...sometimes they're out of spec.

I probably need to get one of those multimeter testors now.

Otherwise I have no Idea how to test the plugs/ plug leads.

What is odd is that the car runs perfectyl fine once it is fully warmed up.

Absolutely...get a cheap one to start. Any parts shop should have a decent one. Fluke makes great ones that start around $60. Sears has good ones too.

You might be surprised at how useful it really is...I'll bet I use a DMM more often than any other tool on my cars & bikes.

NEW symptoms
I went on a trip to LA
got 27 MPG :/ not very good at roughly 75/ 80 mph the whole time.

Also I put the car in Nuetral when going down the grapevine.
After cruising at 85 mph down the hill for a couple miles I finally put it back in gear and got ready to cruise the blank flat highway.

Well when I put it in gear the car was jumping, buckig and hesitanting, as well as Bogging. Every once in a while cruising at 75 the car would do one buck, or maybe two then keep on going... kinda scary when cruising a 450 mile highway.
