97 Eldo, hard start, stumbles.


Recommended Posts

97 Eldo. 63k very slow to start on first start of the day and sets po325 code(knock sensor module). It acts like an old Chevy on a cold morning in that it seems to fire for several seconds before it actually starts-only you can't pump the accelerator on the Eldorado. If you turn the ignition off as soon as the engine starts, it will restart normally and will not reset po325, or any other pcm codes for the remainder of the day no matter how many times you start it. Once started the car runs fine and performance is normal. Turning the ignition on and waiting a few seconds, in case fuel pressure is bleeding back has no effect on the problem.
