Weird clutch issue
 
I have an se with 13bt and an LT-10s with ign box and msd blaster ss coils. I have had trouble getting it to idle. I just installed a aeromotive fpr and finally got it tuned for idle with that. I took the throttle linkage and adjusted it so the car idles at 1800 so it won't stall out. It will idle at 800 but dies when it warms up. AFRs at idle are around 12 or slightly less when warm. I also cannot start the car when warm(nothing to do with fuel adjustment) I think its some sort of electricall issue. I am thinking this may tie into this but I am not sure...If i depress the clutch pedal while at idle it will drop to 1200 rpm and then die out if I hold it for more than a couple seconds. While at 3000 rpm it drops to 2500 and will almost die with the clutch is depressed while in neutral. while in gear it drives alright. Is there some electrical switch to the clutch pedal that could be messing things up?? Does this sound like a transmission issue that while in neutral there is resistance and more load creating my idle mixture for neutral out of sync with when the clutch pedal is depressed and the clutch is not touching the flywheel? btw my timing is advanced to almost 20* just to idle it at 800rpm.

I had a problem like this. Pulled the engine out and timing gear was all fucked. Car had alot of ecenetric shaft play.
Id put alot of money thats your problem. everytime you push your clutch engine goes clunk to the back of the car and looses compression.

well your right, my gears must have been grinding also. there was a about a 1/4 cup of metal dust/shillings clumped into a ball in the oil pan as if there was a magnet right there. Do you think all rotor and stationary gears were destroyed?

Its a possibility.

Arnt you the guy that was having a problem with the car warming up and then swtiching off?

If you are. It is starting to make alot of sense. Everytime it warms up, bearings are jamming up.

Pull down the engine. Tell me whats damaged pm me.
Ill ship you up all the parts you need and help you out alittle bit.

Id say the rotors SHOULD be ok. But your stat gears/bearings/shaft/oil pump/ timing gear is gona Be fucked.
Like i said pm me and ill help you out mate tell you where ya went wrong, i build alot of engines.
