HELP! 5th cyl. is not firing when engine is cold

Hello my 99 P71 Vic has 110000 miles on it. There are 2 problems the
first and most concerning is that recently when I start the car it
runs like crap. There's a loud rhythmic hissing sound and it feels
like it will stall at any moment. The Check engine light flashes
while this is happening. AS I approach highway speed 65-80mph the
problem persists but the power is somewhat restored and the engine
light is on steady (no blinking) then after a little while 5 minutes
6-10 miles the problem vanishes as if engine temp has something to
do with it. Although this time the engine light stayed on, even
after the problem went away and I shut down and restarted the car.
A computer diganostic revealed that the 5th cyl. is not firing when
engine is cold. Hmmmm? Why only when the engine is cold? What could
be causing this cold problem that goes away when the engine is hot?


The second concern is the tyranny. When lightly accelerating the
engine whines up before shifting into OD, it feel like the tyranny
is slipping.

HELP!

Re: HELP! 5th cyl. is not firing when engine is cold

The cyclender spark plug or wire or dist cap (or if it has multi coil system then the coil could be bad). As for the tyranny, it maybe caused by uge and bad pears. But for the transmission, it maybe caused by age or bad gears, or since the engine is loosing power it could effect the tranny, or your low on tranny fluid. Don't take any thing I type offensive, I'm just boared.
