Hi

350 TPI starts fine and immediately after this the rpms going down and down and dies...

if I put the gas pedal it idles great with no strange noises bogging etc, whenI reving it also everything is ok.

what should I check? IAC valve?

 

Your TPS and Min Air is out of adjustment. No big problem.
Follow this procedure to the letter. It will get you fixed up.

will that work for a SD car as well? my 92 TA does the same thing sometimes when i start it in the morning.

 

SD?

 

speed density ? I suppose yes
today evening I'll do this to my car and we will see a result

but in my case interesting is that my car rans fine three days ago when I drove about 100miles....and I parked the car and yesterday when I tried to start situation like this :/

 

Not awake yet!
Yes, same procedure

Ya never know about sensors...good one day, bad the next. It's defiantly worth the effort though

 

Same issue with my car, i drive it daily and it will do the no idle condition once a week or so, always in the morning

 

Sounds like sticky IAC. Remove it and clean it up/replace it and then do the set procedure for it.

after adjustment the car idles ok. but sometimes shakes little bit so next step is to clean the IAC.

but in my opinion the problem happened when I take the battery off the car to recharge when I parked car. Looks like the memory in ECM is not good and ECM lost the sensors data? ECM replace?

EDIT: can sticky and clogged IAC can cause slow reaction to gas pedal? I also have a 99 M5 and gas reaction is totally different.
