700 is a generic transmission code. It went to limp mode, that's why it drives like it does. Have the codes read with a newer /better code reader or a scanner. Find out what other codes are in there.

check catylic cowntor ,fuel fiter air filter.

I know this might sound dumb, but it has happened to a lot of people - make sure your floor mat (not even a corner of it) isn't on top of the accelerator pedal. Even the slightest weight can cause the pedal to accelerate enough to be noticeable.
Not dumb, it's a good answer. The floor mat can slip forward (and has) in two of our new vehicles when we were driving on the highway. It had worked its way off the anchors and slipped forward, causing the vehicles to accelerate. I put the gearshift in Neutral, pulled off the highway and that was the problem, both times. I don't think it was on top of the gas pedal, underneath, but still pressing or I guess, pulling the pedal down.

All of these are good answers, but if it's an automatic transmission, it might be normal provided the engine performance is ok. Auto trannies have a torque converter stall speed. I have a 96 Cadillac Fleetwood and it will move on its own.

Your Have to check your clutch lining it might be worn out. Your have to call mechanic to do this job because he will put down the entire transmission to replace that parts. This Problem Call Clutch Sliding.

transmission fluid. you need some. ours did the same. fix it fast, before you damage the transmission.

this is usually due to a dirty throttle body. just beware if you do try to clean it you will need to preform the idle relearn procedure. this does work, ive done it personally.

A. Accelerator Pedal Release Position Learning Procedure.
1. Make sure that the accelerator pedal is fully released.
2. Turn ignition switch “ON” and wait at least 2 seconds.
3. Turn ignition switch “OFF” wait at least 10 seconds.
4. Turn ignition switch “ON” and wait at least 2 seconds.
5. Turn ignition switch “OFF” wait at least 10 seconds (how would you know if you get it right?)


B. Throttle Valve Closed Position Learning
1. Make sure that accelerator pedal is fully released.
2. Turn ignition switch is “ON”.
3. Turn ignition switch is “OFF” wait at least 10 seconds.
Make sure that the throttle valve moves during above 10 seconds by confirming the operating sound (i never get this right because i never heard anything)

C. Idle Air Volume Learning (Throttle Position Learning)
It's best to time with a watch/clock.
1. Perform “Accelerator Pedal Released Position Learning”.
2. Perform “Throttle Valve Closed Position Learning”.
3. Start engine and warm it up to normal operating temperature.
4. Turn ignition switch “OFF” and wait at least 10 seconds.
5. Conform that accelerator pedal is fully released, turn ignition switch “ON” and wait 3 seconds.
6. Repeat the following (steps 7a, 7b) procedures quickly five times within 5 seconds.
7a. Fully depress the accelerator pedal (HARD)
7b. Fully release the accelerator pedal.
8. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 20 seconds until the Check Engine Light (CEL) stops
blinking and turned ON.
9. Fully release the accelerator pedal within 3 seconds after the CEL is ON.
10. Start engine and let it idle.
11 Wait 20 seconds
12Rev up the engine two or three times and make sure the idle speed and ignition timing are within the specifications. (this is fine because SES light lets you know if you did it right the way it blinks)

you need your throttle positioning sensor replaced and set.
