low idle/stall when clutch pushed in.

[HighPsi92GST]

okay the car is a 93 5 speed, turbo awd, the engine had just been rebuilt by some company that didnt do that great of a job. they also put an act 2100 clutch in it. the guy who owned the car had problems right after he got it back so he sold it for really cheap, i bought the car knowing it had problems
also the mechanic that did it told the guy i bought it from that there was a ball in the trans that was a little messed up and needed to be machined. the guy didnt know much about cars so just said he would get that fixed later. so i there fore dont know what the part is, or whats wrong with it, any ideas?

now for the stalling, what happens is that when the car gets up to normal operating temperature, and you push in the clutch, the car will drop to 400-500 rpms and run real rough. it sometimes even stalls.
car is all stock. i checked the ecu and swapped in another one, problem did not go away. looking for any and all ideas of what could be wrong with it. thanks in advance for any help.

I am not sure that is the problem on this one. On the 1gs the Reed switch is there (what they are referring to AWDs did not have a speed limiter) to keep the RPMs up when you were stopping to help the brakes.

If the car is idling fine and you push the clutch in it dies you have one of 2 problems.

#1 the car can't adjust the idle. This could be as simple as the biss screwed in too far. Do you have any other idle problems?

Your ISC could be bad.

#2 (most likely since the worked on this) the car is having a problem with the clutch dragging on the flywheel. This can be caused by many different incorrect setups.

Pust the clutch petal in slowly until it stalls. Does it stall before you can shift? does it stall after you can shift? does it always stall?

It may be possible that they shimmed the ball too far and your pressure plate fingers are contacting the clutch plate and causing drag that is stalling the car. Does the car shift smoothly?

Give us some more info on this and I can help ya more.

Okay, yes the car idles completely fine and everything seems to be in working order. it idles really smooth too (no jumping) and is idling at a good rpm, not too fast, not too slow.

so as for #1, no i dont have any other idle problems. its just when the clutch is pushed in that the problem comes up. if it wasnt for the idle being fine all the other time, i would think it was the biss. but if i push the clutch down and it drops real low in rpms, then let off real quick, it goes back to normal idle.


as for #2...thats more what im leaning towards as the problem. the guy i bought it from could only remember that the mechanic had told him a ball needed machine work done to it, and asked if he wanted it done. the car owner said no he would hold off on it. sooo they put the car back together as it was with a new act2100 clutch, and didnt machine the ball they spoke of. they told him it will eventually give him trouble and will need work done. if you think this is the problem, could you give me some info on what it is, does, can be replaced? fixed? i dont know much about trans and stuff like that.

the main thing is, what ever is going on has caused a rod to start knocking (or atleast i think it is related) and i cant test the car too much for fear of a bearing spinning. i have a 6bolt bottom end ready to go into the car, but it was just built up and dont want to risk damaging it before i find the problem with the car.

as for the stalling, it doesnt always stall. if i am sitting perfectly still and push the clutch down, the car will go real low in idle as the clutch goes down and OCASIONALLY stall when it bottoms out. but not all the time. the car its self seems to shift a little hard, i almost have to let the clutch drag when i pull out as it wants to stall when i am letting the clutch out to pull out.

so if you think it is a trans related problem give me some info about that. thanks. i really want to get this car working.

Is it possible that somebody put a 7 bolt motor in the car???? If so things aren't looking too good. If you know you have a 6 bolt they may be talking about the pivot ball that the clutch release fork rests on. If this ball wears down the clutch does not get the motion that it needs, but your car would only stall like that if the car was in gear. I am trying to figure out what ball they are talking about.

thanks for the help everyone. its a 93 tsi, so it has a 7 bolt.
I think i may have found the problem. its not confirmed yet, but pretty sure of it. seems that the crank has taken a small walk.

 

[talon1979]

I am sorry to hear that. I always forget the 6 bolts end in 92 otherwise I would have mentioned crankwalk earlier.

Good thing you have a 6 bolt ready to go in

no time like the present for the swap.
