problem in reverse
- Thread starter japakos
- Start date
It drives fine. no problems! When I put in reverse , I move a bit and when it hits 1600-2000rpm the car shuts off! It does it every single time! I've unplugged everything I could think of , reverse valve, tps, speedometer, nothing. If I slip the clutch it moves, if I release it, bang.. dies. What I mean is that if I slip the clutch and go pass 2000rpm it doesn't die, but if I release the clutch 3/4 it dies

only thing i can think of is to check the reverse switch wiring. maybe it is shorting somewhere and causing a strange spike related to the tps sensor or something???
if you put it in reverse but keep the clutch pedal down and try the gas pedal does it act funny at all?
electrically reverse should be no different to any other gear (other than the reverse switch). mechanically it sounds like its working ok.

Checked the wiring is ok. It acts like that and wants to die only when I let off the clutch. Once the clutch is at 3/4 it dies as soon as it hits 2000rpm! I don't understand. Maybe something in the gearbox? Everything electrical is ok, nothing touches nowhere the chassis, no shorts no nothing. It must be something mechanical but what?!??
Example: Let's say I put in reverse, steady 4000rpm, clutch pressed. No problems. Once I let of the clutch , car tries to move, jerks and dies. ONLY in reverse! wtf is this? lol

Hahaha.. this is indeed, a ghost in the machine.. 
I agree to that but I think it would behave like that even when the wheels are jacked up? Or maybe the box is broken and it does that when it takes load? Any ideas? and only in reverse? It makes a lot more sense if it was 2nd, or 3d, or whatever gear, the car is 230hp. But reverse? ? OMG this is a joke lol
UPDATE
I haven't figure it out yet but today it developed a new problem. As I said before, the car drives fine and does this shit only in reverse. Now, if I move let's say on 3rd gear, 5000rpm and go full throttle, and let it go suddenly, it shuts off for a split second and turns on again. For a single second while the engine moves when I let off the gas. This gives me the impression that when the engine moves forward something it gets disconnected or whatever. Any ideas?

If i were you id check the loom for broken wires. Sounds like when you move it in a certain direction it shorts and dies.
I found out the the small boot on the starter's positive wire was not covering anything lol. And I had my rear engine mount loose so it must be it, I haven't moved the car because I am installing a new coilover kit. That explains the split second death If + touches the ground for a second strange things can happen don't you agree? When I'm done I'll let you know. Thanks everyone
