When you get up to 25 mph, what does the tachometer read? Is the engine revving very high?

Is the check engine light on?

Customer: replied 7 years ago.

tac seem normal, engine is not revving, no check engine light, thought it might just be in computer system someway. Is there something in computer system that makes it think it has rolled over or something like that? I've been reading all i can find about safety features on this car and thought something is making it think that, I don't know, I been trying to figure it out.



Expert:  Matt Hardy replied 7 years ago.

No, there is no rollover sensor that would keep it from running.

This might be a problem with the electronic throttle system.

Check the air filter first.

Then try disconnecting the battery for 10 minutes.

Then reconnect the battery and see if it runs better.

The car starts up fine and runs fine, just can not get over 35 mph, I'll check the things you said and see what happens. It is just blowing my brain in solving problem. I hope it is one of your ideas. Thank you for you help, Is there someway to get back to you later ?

Hopefully one of your ideas will work, I would like to if it does.


if it works, Thank You,
