Does the IAC valve replace the cold start valve or injector on a 2000 camry v6

IAC or idle control valve would be unlikely to replace a cold start sensor or injector
run the fault codes and check for ambient temp sensor problem that is not telling the ECM to rich up the fuel mixture ( choke ) for the cold air coming in
the ECM will adjust the idle speed accordingly to the responses from the temp sensor

I had just put a new block in my 1997 320i E36. Everything has been put back nicely and perfect. When Itry to start it starts imediately but can not idle.It also produces this poppinp sound like it's short...

it could be the idle valve on the front of the engine, or you could have an air hose not correctly fitted, try removing the idle valve and give it a good clean with some brake cleaner, tap it a couple of times and then refit it, the other one is check all the hoses arround the throttle housing, and below it, it could be you have a traped hose not letting air in...theres a couple of things to try first

The Rav 4s have 2 issues firstly the injectors can leak and this causes a strong fuel smell on start up,even cleaning wont fix it they need to be replaced,and secondly valve stem seals go in them meaning on cold start up it will blow smoke for a few seconds,these are the 2 most common issues as i work for Toyota and see plenty of them

Suzuki Grand Vitara 2.0 litre petrol. Starts from cold (stood overnight). Twelve minute drive to work - slowing down at lights etc engine stalls constantly. No problem re-starting. Pull into a layby...

Same problem for me. The car would idle at about 2500 when started from cold and about 3 miles on would not idle at all, resulting in the revs dropping off when changing gear or stopping. Also rather jerky in top gear unless thrashed - numerous trips to the garage for air idle valve, injectors etc. but still a problem! Have just found out that GVs are a bit prone to carbon build up in the throttle body - mine was almost blocked - it now feels like a different car.

Mercedes benz 190e 1900year /air flow meter connections

AS far as i understand it your air flow meter only controles your idle, not your air/fuel mixture. The mixture is controled by the Air/fuel mixture body that sits immidiatly below your fuel distributor. it has a 'tower' that reaches up to a hole in your aircleaner so you can get to it with an allenkey. To set the mixture correct it needs the aircleaner on. that screw changes the pivot point of the arm that gets depressed by the large round disk visual if the aircleaner is of. This is not a throttle butterfly, it mechanically 'measures' the airflow by being sucket down and pushing a plunger upwards into the fuel distributer increasing the amount of petrol to the injectors. You say gas as a supplement... I assume you mean Hydrogen Fuelcell. Because if your trying to 'add' instead of replacing with LPG or Natural Gas you will have a problem as LPG for example needs to ignite earlier. For example if the petrol engine fires at 6 deg BTC on petrol, than converted for LPG it needs to fire at 16 deg BTC on their original plugs (newer plugs are available that allow for an acceptable setting suitable for both fuels but all i everseen when petrol was still present when switching to LPG is an 'engine bay' fire)... But assuming your talking Hydrogen fuel cells as a supplement to try and reduce your fuel consumtion than the element that could create a problem for you is the Lamda probe (Oxygen sensor) in your exhaust as it may think that your fuel mixture is to lean and tries to increase fuel through the cold start injector or the electronic pressure regulator on the fuel distributer. I hope this will help you somewhat.
