My 02 dodge stratus 2.4L on occasion will jerk while driving and when I press the gas it will not accelerate and the rpm doesn't move to speed up. When I pulled over it shut off but after letting it sit for ten or fifteen minutes it started and was driving like normal. I've taken it to the shop and he couldn't figure out what's wrong with it cause the car was doing fine for him and no codes came up on diagnostic test. Please help!!

This sounds like something that happened to my Stratus.....my problem turned out to be the mass airflow sensor located on the intake manifold. Super easy to replace, one connector and two screws. Not hard to do it yourself.

SOURCE: ENGINE CODES; NO ACCELERATION

Well this one will be a tough one.
P0761 is shift solenoid 3 malfunction. Most likely caused by a broken valve retainer in the valve body.
The other four codes well that may be tough to diagnose. See P0171 and P0174 are bank 1 and 2 are lean and
P0172 and P0175 are bank 1 and 2 are rich.
To have both banks coding rich and lean would be extremely rare.
I suspect you have a couple of problems like may be a MAF sensor problem, a vacuum leak, and maybe a restriction in the exhaust.
The exhaust restriction would be easy to diagnose. You would need a vacuum pressure gage and hook it into the hoses from the DPFE sensor. You should have 1PSI or less at idle and 3-4 PSI at wide open throttle anything more would be a restriction.

ENGINE HESITATES WHILE ACCELERATION

It can be fuel pressure issue or it's the problem with accelerator pedal or its clogged filters causing there.

I have a 2005 Chevy Uplander, and when driving on the highway at about 60-65, the van occasionally drops RPM's and when you press the gas harder, it recovers without any jerking or anything. The same...

This is a rare one and can be tricky. Since your rpm gauge rises back up when you increase your acceleration slightly but you feel no jerking of acceleration then this tells me that a speed/rpm senser either has a bad connecton or the sensor itself is going bad when the engine reaches an optimum heat while driveing on the highway. Since you feel no acceleration when you slightly press the accelerator down but yet the rpm gauge is increasing back to normal, the throttle body sensor may be compensating for the failed speed sensor/failed sensor connector. Please get your uplander diagnosed properly first to confim this.

My 1996 dodge stratus idles rough, shaking the steering wheel. Also just recently driving my normal comute to college and back which is 40 miles round trip, in turn is now consuming 4 gallons of gasoline....
