Unhappy my baby is stalling and it isnt the MAF

So, ever since I moved down south I been doing a lot of driving, I realized my 94 4runner keeps stalling at idle when Im at stop signs and stop lights or turning,its like im going 2mph than it regains speed after pressing my foot down all the way on the gas pedal, I recently replaced the alternator, the spark plugs and wires, my belts, fuel filer, my rotor button, and my battery, I also cleaned my MAF, but nothing helps its still stalling n theres no engine light coming up, what could be the issue i need advice, I'm bringing it to the shop tomorrow cause my diy tricks all failed.

Not true. If there are dead spots in tps it can jerk around. Check the tps

I don't see anything about what motor is in 4runner, auto manual trans, and doesn't it have a VAFM? did you spec it? I don't get the pic either
