Engine dies when clutch engaged

[DMiller]

Car in question is a 1989 240sx that was converted from sohc/auto to a dohc ka and 5 speed swap. Car has a stock flywheel, exedy stage 1 clutch, s14 transmission, relatively new slave cylinder (was installed when swap was done). The engine is a 95 S14 engine, only a cone filter and emissions delete, s13 dizzy, ecu, and harness.

The car ran fine till about 3/4 the way through a drift event when it would suddenly die when the clutch was engaged. With the car in neutral and not pressing the clutch, the car will start, idle, and rev fine. But the second I engage the clutch to put the car into any gear it suddenly dies. I did rub through 2 wires on the passenger side harness that runs under the fender, I fixed those two wires and went through the rest of the fender harness to see if there were any more damaged wires and I didn't find any.

Any and all help is appreciated.

Just had this problem, I was gona post in this thread to not make a new one, and to find the answer. OP has probably found the answer but I want to post it here because I couldn't find the answer searching. wish people would fallow up.

runnin a 91 ka24de
Symptoms:
-Car died at WOT with no warning *UNDER LOAD!*.
-car starts and idles while engine is warm.
-car bogs down between 1-2.5K / 3K+ car will rev with no problem to redline.
-cold engine; car will have a rough idle, in some cases stall, will backfire through the intake when idle is opened above half way.
-call will stall under any load (trying to drive in gear)
That's all I really did before I found the problem.

Anyways, I trouble shot my maf, tps, plugs, and narrowed it down. I ended up trying to clean my maf, no change. Cleaned out my iacv with some seafoam thinking it was clogged. Took a look around since I didn't have white smoke coming out the back!! That told me that the seafoam was not going through the engine, thus a leak in the lines. (seafoam will push a thick white smoke out your exhaust for the lesser inclined) Found a wet spot coming out a huge hole in the back iacv hose. Swapped it for a good one and it fired up with a clean, strong idle. Seafoam ended up cleaning some shit out of the vacuum lines and lowering my idle as well.

hope some people find this helpful in the future.

scratch that, i did fix the idle with the leak, but its still stalling out when i put it in gear. ill update this when i fix it tomorrow.

Update-Fixed: Had a few wires worn apart on harness, black with a white line in it. Pretty sure its the TPS wire in the harness. Spliced a new line it, re-tucked it, running better then before. TPS was the problem, just not the sensor it self.
