Stalling and sometimes jerking

My car keeps stalling on me. Slowing down for speed bumps, or stop signs, and just recently entering the freeway from a off ramp. And sometimes the car jerks but doesn't stall. I am from Minnesota and someone said it was the cold weather, at the time it was below zero. But on the freeway today it was 30 degrees and I had been driving for 45 min. I took it in a while back and they hooked up a computer to find out why my check engine light was on. I got no answer. The check engine light hasn't come on since. Please tell me why my car keeps stalling so I can fix it before I stall on the freeway with my family in the car. Thanks.
Do you

Is the check engine light on? If so I would start with a scan of the computer to see what failures it has logged. This will save a lot of guess work. Also look for obvious issues like the intake hose from the air box to engine having cracks or holes in it

Read these guides, they will help you figure it out

My 2006 Toyota Corolla began stalling while driving. It began with the car having a brief stalling occassinally for several weeks but recovering again. With time it completely shut-off while driving. I checked the internet and found out that there was a recall for the ECM (Engine Control Module) however it had already been replaced on my vehicle. Took the car to a Toyota dealership mechanic who stated that all the diagnostics tests he performed came normal. He noticed that one of the battery terminals was loose causing the problem. I told him that the car was supposed to continue running when you remove one of the battery cables, since the alternator keeps it running. However he said that since the problem was intermitent the car computer interprets it as a malfunction and turns off the engine. He tighten the battery terminal and on I went. Few days later the problem began again. On my way to a local mechanic I noticed that the car completely stalled when I turned on the A/C while the car was running. Made to the shop and explained what happened. He ask to start the car, put it on drive and then turn on the A/C. Right there he noticed that the car was revving to low. He proceeded to remove a part from my car that contained the choke plate and it was very dirty with soot or carbon deposit. He proceeded to clean it with gasoline and a rag and reinstalled it. Voila. The car started running smoothly again and did not stall when I turned on the A/C. He explained to me that with time this carbon deposits form in the choke and it is unable to open completely. The ECM attempts to increase the air intake but with time it gets to a point that it cannot get enough fuel mixture in the engine and it stalls. The good thing he charged me only $45 for the repair.

Electrical problem
2005 Toyota Corolla 4 cyl Front Wheel Drive Automatic 54k miles

I have checked EFI and EFI2 both check good and have voltage in the on key postion. EFI relay and c/opn relay meter out at about 112 ohm. And open on voltage side. Both change states in the on postion. But I still do not get power at my fuel pump. The fuel tank indactor has voltage, But the black and red wire on fuel pump is none. The ground on fuel pump checks ok. It looks like from the c/opn relay its comes to ID (pin 19). Theres is no room to test there for voltage. Any help or ideas.

Block open the airflow meter and see what happens-it completes the COR ground circuit

By block open airflow meter you mean disconect? If so I just tryed that and the V3(evap). Both grounds on the connectors are good back to the battery. Thanks for the idea, and if that is not what you ment for me to do please let me know.

Check for a flap in the AF meter block it open. In the diagnostic check connector jumper Batt to Fp-did the fuel pump come On

Ok, I see why i did not understand now. The airflow unit I have does not have a flap it has amber thirestor (diode maybe) on the six o'clock side and inside the left hand side i see the resistor looking things that do not move. The amber thirestor ( not sure if that is what it is) but is ohms out at 1.8Komh. I can not reach other 2 resitors on the inside. Is there a way to do this test with this type?
(in the pic resitors are on top)

Did you try jumping the DLC Batt to Fp to see if the fuel pump come On when key at run

I went from ID 19 to DLC batt and yes the fuel pump comes on.

Edit: Ok so I assumed that I would get voltage at the pump in the on postion. But, I dont but when I engage the starter I get the 12V at the pump and it is working but, the car will not fire. It turns over but never starts. Where do I start on that problem?

Car died while sitting at a stop light and would not turn over.
It will turn over and start then dies. Acts like it's not getting fuel. We have replaced the fuel pump but still does the same thing.

Disconnect a plug wire or 2 ground it to the engine -have helper crank engine over-Do you have spark-if so check for injection pulses from the injectors-is it clicking while cranking-

Did you test the fuel pressure before changing the fuel pump. If not, that is your first step.

Car has an ignition coil that mounts on top of plugs can I test this the same way by pulling the coil off and ground it? Or do I just pull it and the spark plug and watch plug for spark?

Hi IMHALL14,

Here is a link to an article from this site that features written instructions and pictures showing and explaining the process of checking the fuel pressure yourself. If you decide you would like do this yourself you can purchase an inexpensive fuel pressure gauge online from sites like Amazon.com.

Thank you for visiting 2CarPros.

Kindest regards,

All four sparked, a yellow spark not blue like I was expecting. But each have there own coil so I assume thats normal. All plugs looked ok also.
