cant figure this out.

Engine system fault / gearbox fault lights coming on and the engine is revving. This happens after the brake pedal is depressed. Then the engine starts to rev up but the car hesitates.

Also having another issue.. The back up sensors are causing the amber dash light to come on and the sensors are no longer working properly. This only happens when in reverse obviously. Also, causing the rear lights to malfunction and not illuminate as they should almost like the wires are crossed.

Thanks

 

i never seen any reply to afonda mess i have the same prob. what is it?

 

Check the wires at the connector for the throttle position sensor. It's completely unreasonable how the computer reacts to such a seemingly small issue, but it was 100% the issue that solved the exact same symptoms. One wire was loose.

 

I had the exact same problem 2 weeks ago. The yellow wire on the throttle body plug came loose.

The yellow wire pulled out while I was working on the manifold over two years ago. I reclipped the wire, pushed it in the plug harness and then filled it with silicone. However, driving on the wonderful roads of Chicago with all the potholes must have backed the wire off.

If those wires are all OK, check the brake sensor. You stated it only starts after you press the brake pedal. Does your "brake" light, lower right on the dash - red, come on?

 

It was the yellow wire for me too. I'm assuming there is an ergonomic issue with how that wire is physically pulled and tugged on when you remove the intake elbo. My suggestion is to unplug it before removing the and rolling the elbo out of the way.
