Engine Stops When I Put To Reverse (Sometimes)

[udda]

hey guys ,

i have 2003 cs3 manual gear car , recently it started to stop the engine when i put it into reverse ... any idea ? Mileage 132. i was wandering it occurs when it comes to idle or something

Thank you

When exactly does the engine stall? Is it while holding the clutch pedal down (as soon as the gear enters reverse) or is it when you start letting go of the clutch?

hey davy ,

as soon as the gear enters :/

That's strange... Do you have trouble shifting into reverse or does it enter smoothly? How about other gears? All smooth??

I can only think of the following:

1. Electrical - The reverse light circuit causing a short with a vital circuit of the car. Can cause the ignition system to stop functioning or something.

2. Mechanical - Your hydraulic clutch slave cylinder behaving erroneously when shifted to reverse and causing the clutch to engage. If this was the case, your car would slightly jerk (similar to what happens when clutch balancing fails) or hear grinding noise.

3. Mechanical - The transmission itself having an issue. Manual transmissions rarely give issues like this, so I'd be surprised if it was an issue with the gearbox itself. Again you would probably notice abnormal grinding/clunking sounds if it was something wrong with the transmission.

Interesting to see what others have to say.

davy ,

no trouble and yes all other gears are smooth ,

actually there was a small incident happened like once or twice , while the engine is on and the car is just parked i tried to roll down the shutter engine died , i was wandering this was an electrical issue due to this but now it happens when i put the reverse gear. ( this is not a full option car , but converted )

mmmm may be i should do a engine tune up n see noh ?

I now have my bet on possibility number 1 listed in my previous post.

I doubt an engine tune-up will address your issue. A tune-up covers the cleaning of the fuel system and throttle body and is unlikely to address any electrical issues.

Try this:

- Locate the fuse related to the reverse lights (Since this is a converted Lancer, you might want to check if the fuses actually belong to the circuit indicated on the diagram on the fuse box cover)

- Remove the reverse light fuse (Alternatively, you can remove the reverse light plug connector on the gearbox. It is located just below the air filter, where gear lever cable meets the gearbox)

- Start her up and shift to reverse

If the engine doesn't stall, then the is a very high probability that there is either a short circuit or incorrect wiring on the car.

davy ,

hmm yeah i thought of a tune up coz it stops when u put to reverse anyway u makes more sense , okey will try it and let you know bro

Thanks a heaps

Cheers

Davy ,

i checked all the wiring and put a direct connection to the shutters control panel , so far so good ...

thanks a lot bro

Did this also solve the stalling problem when shifted into reverse?

Davy ,

Yes all sorted .. so far so good .... the issue was with the control panel (Shutters n locking)

thanks bro

cheers
