LIstees,

On the way home from camping about 4 hours away last weekend my 81 lost
power considerably.  I believe she is getting spark and fuel because she
will idle real roughly but will die if I remove any of the 4 plug
wires.  The exhaust has a white color to it.  I don't have a compression
tester but I'm thinking it might be a stuck valve or something similar.

My problem is I've never done any valve work so I would appreciate any
thoughts on my situation and any pointers or suggestions anyone might have.

I did buy one new fuel injector and replaced all of the old ones one at a
time with the new one.  It ran about the same each time.

Thanks in advance,

dylan
