I cant solve corolla stalling when stepping on the gas?

OK it doesn't have a AFM it has a MAP sensor, it is a little black sensor on the firewall it has a small black hose going to it from the intake manifold and 3 wires its, by the windsheild wiper motor, test that and see if thats your problem....

i have tried a used MAP sensor.. Still no go.. But i do think it is somewhere in that area.. some suction or vacuum problem.. hmmm

put some soapy water on your vaccum lines and then check for bubbles. where there is bubbles there is leaks. Also you can go lines from menards for like 2 bucks and do all the vaccum lines just to be sure.

Take it to a shop to have it diagnosed. Then get the part and repair it yourself. Otherwise your just gonna keep throwing parts at it which will cost you more money in the long run...if it already hasnt.

Scorpiox, have you tried testing the injectors? what about the fuel filter and pump??

[Beemik]

it could the injectors or the fpr valve. if you are stepping on the gas and the cel comes on it could be because the af ratio is too lean meaning lack of fuel. i would imagine if it was a vacume leak the car would idle high. i would check the injectors or put the old ones in if that doesnt work i would try the fpr

Check your oxygen sensor. It may be running to rich to quick due to a faulty o2 sensor. I'd try checking what's listed above and the o2 sensors.

Pull out the o2 sensor and hit with a butane torch for 3-5 seconds at a time to burn off all of the build up. Don't hold it constant though, that would be dumb.
