Somwetimes it will restart before I come to a stop, and other times I have to restart it after stopping. Its like the engine ignition has been turned off. What could be causing this to happen. :

Could be a crankshaft position sensor or the distributor pick-up and also a failing fuel pump.

Duplicate the problem-then immediately check for spark and fuel pressure.

I bought the repair manuel and the check engine trouble code is (34). It indicates that there may be a open or short circuit from the IAC valve to the PCM. Or the same between the IAC and the fuel injection relay. Could this be causing the the cars engine to act as described above.
