engine randomly dies

[Irukandji]

Hey guys, before you flame, YES I DID SEARCH. I searched previous threads and didnt find exactly what i was looking for (but did come across many similar threads).


Anyway, heres my problem,


I'm driving .. approaching a light, so i downshift then push in the clutch before i stop, my idle goes to about 200-400 and my engine shakes a little then dies, so i hafta restart the motor, the idle flucuates from 200-600 and occasionally dies, so i hafta keep my foot on the gas pedal to keep the idle up. It did this about 4 times, but now I drive the car and it drives like normal! doesnt stall. Any idea what could have caused this?

I checked the vacuum lines and i really doubt its a MAF.

Any help will be greatly appreciated.

Re check the vacuum lines and the maf your plugs and the voltage to the ignitor and CAS.

Silbeer is correct. I had the same problem long months back. Checked all vacuum lines, all were good, turns out it was the brake booster hose that had a crack that would open from the engine torquing(sp?). Sometimes resetting the ecu can help with trimming out how the engine performs. Good hunting.

I had the problem in my se fastback years ago. never did figure out what the problem was, but it would do it 1-2 times a week. I searched for ever but no luck. Eventually over a winter I ended up going to electric fan, jwt ecu, removed all vacuum lines except for the nescessary ones, injen intake, and underdrive pulley. After that it never did it again so I don't know but one of those fixed it. I also did a complete tuneup on it that winter too, flush and fill, oil, plugs, rotor, cap, wires, etc.

Haha, the mystery dying KA motor. . .my car will do that every once and a while. I don't even worry about it anymore.

I say reset the ecu also.
