Car acting STRANGE when its cold.
Monday and Tuesday have been cold out where I live. This issue started Monday.
Monday I start my car, it immediately starts and revs to 2,000 RPM'S, as the RPMs go down over a couple seconds thr car will bog out and die if I don't give it gas. The car will stall when accalerating from complete stops.I drive 5 minutes to McDonalds cuz I was hungry...FIVE minutes. After being there for half hour. Icome out and car starts fine. Like a champ no stalling either. Go to work for 7 hours... car starts like a champ and doesnt stall at stop signs and red lights.
Tuesday morning, car does thr same thing when i start it. Drive THREE mintues to my grandpas...able to start and run like a champ.
What is going on with my baby?? I have no check engine light. I DO have an exhaust leak but nothing major. The bogging out on start problem will go away after wrestling with it for 2-3 minutes.

The IAC valve is the only thing left.......
The MAF and the 02 sensors can tell the PCM to make the IAC valve act wacky. The MAF controls the engine when it's cold. After the engine warms up the 02 sensors take over mostly.
So maybe your MAF is failed and you're just not getting a code and a ses light. Failing 02 sensors can also cause your problem.
So......it's simple. Start with an OBDII scan with the engine running to see how the 02 sensors are switching. The MAF signal can also be checked.

So basically get into my throttle body area and check the MAF and IACV (by the way where is thst located exactly) and if that doesnt solve my problem I should scan to see if its 02 sensors?

Both have one plug on them.
Do what's free.....get a new MAF and out it on, see if it works. If it does then you needed a new one. If it doesn't fix it return it and go get a scan to check the 02 sensors.
