I have recently developed a stumble when I start off from a stop in
first gear or when I am down around 2K RPM and I floor it.  I am leaning
towards a spark problem since it is such a harsh sudden stumble when it
happens, almost like the engine dies for a millisecond and then kicks
back in.  I replaced the spark plug wires and checked the plugs.  It
seemed to go away for a couple weeks and is now back.

 

Any ideas???

 

Thanks.
