1 more thing you had left

is check your sparkplug & ignition system
is it ok or not ,proper wired if not than clean up that connectors & than do again with checking your battery with another same model if started than its 100% fault about your ignition sysytem coil ,

go to your service center they can solve this prob easily after all,
i hope so you dont have to go to center you ca do it yourself,as i had,

SOURCE: 1991 Olds Bravada 4.3 v6 rough idle and backfiring.

Ok guys, let's fix these things here!
Just went through this myself, so do the following:
Go to your local parts store and buy a Haynes Repair Manual.
You need to read the book first, learn how the ECM (Electronic Control Module) works. You'll see that there are alot of sensors and components that make up the fuel emissions bologna.
The nice thing about this system is not only does the ECM control all electrical functions, it also trouble-shoots it's self. When a component or sensor goes out, the ECM stores a code for that event in it's memory. You can use the Haynes Repair Manual to put the ECM into diagnostic mode and thus read any codes present.
So, all that's left is replacing what the EMC tells you too! :) Good Luck!

If it runs that bad, you should have a check engine light and some codes set. Have you tried having anyone read the computer error codes?
Check the plastic tubing from the air filter to the throttle body for cracks.

There is a separate T-piece 3way thermostat made by BMW for the old box shaped 318i and 518i cars. It is a separate unit that fits into the water pipes, and not onto the engine. It has a hot water inlet, and a hot water to radiator outlet, and an engine warming outlet. Each outlet has a thermostat. The radiator on opens when the water is hot, and the engine warming closes when the water gets too hot. The temp stays at 85 D Celsius all the time. Works well on my vw synchco bus and subaru 2.5 engine.

at the engine, there is a small sensor that helps increase or decrease the rpm of the engine. Perhaps yours is soo low, that when you slow down, it's almost about to stop.

The other problem could be the airfilter sensor. If it's not properly fixed or if the sensor itself is a bit damaged, than the engine is not getting enough air and so, let's the engine almost go off.

Please give further details if this has not helped.

thank you

1997 328 i convertable the engine lite just went on just bought

When the "Check Engine" light comes on in the 1997 BMW 328iC, the problem is 99% Emissions Systems. First thing to check are the Four (4) Oxygen Sensors. That is correct your convertible has four O2 sensors. They are about $100 to $118 each, online.

I have done this procedure it is not a big deal. It just requires four sensors. More than likely you and your car experience one or several of the following:
  • Engine will not accelerate and backfires
  • Check Engine light is illuminated
  • Irregular idle during warm-up
  • Irregular idle with warm engine
  • Poor engine performance
  • Fuel consumption is high
  • Driving performance is weak
The O2 sensors reduce emissions and tells the computer how to mix your gasoline to air mixture going into your engine.

Since you say you have a 328, they have either two or four O2 sensors. The 1997 BMW 328 Convertible has four. Your chassis style is also referred to as a E36 series. Your engine is a 6 cyl M52.

Good luck
