style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">I can only offer what I
have done in similar instance. The first thing is these engines are easily
damaged by low fuel pressure. When fuel pressure is low, the engine will run
lean and the excessive heat will damage the rings and you will end up with low
compression. This will exhibit itself as a rough running engine. There are
several major things to make an engine run correctly but the major items are
good rings and valves, good fuel pressure and injectors, no vacuum leaks, good
plug wires& plugs, electrical system, timed properly, and good computer.

ensure you label the plug wires so they get put back on in the proper order.

double check the wiring from distributor to each plug to ensure the wires are in
the correct firing order at the distributor cap and replace the wires if they
are suspect or are the factory originals (as you have done)You should also check
condition of the rotor and cap to see if they need to be replaced (as you have
done).<o:p></o:p></SPAN></FONT></P>

style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">I had the issue three
times that you are experiencing: 1<SUP>st</SUP> time it did not run real bad but
had a noticeable rough feeling due to bad rings on cylinders 3 and 5 due to low
fuel pressure (rebuilt the engine (90,000 miles) rebuilt with race parts so cost
was high ($2500). 2<SUP>nd</SUP> time was due to having the engine out of time.
I had replaced the intake manifold gasket material at the rear of the intake
because an oil leak that had developed (the sealer I used at rebuild did not
hold up: the GM sealer designed for this was used this time and it holds up).
When I put the distributor back in I forgot to disconnect the EST wire in the
cab when I timed the engine. The engine would idle OK but when driven and I
pressed the accelerator it would hardly run. I disconnected EST an timed to 0
Degrees to fix the problem. 3rd time when I floored accelerator engine would not
accelerate well and pinged. I Fixed a vacuum lead that was disconnected at the
tube junction just to the right and slightly in front of distributor.

<P class=MsoNormal><FONT face=Arial color=navy size=2><SPAN
style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">I approach these issues
in this manner. If you have fuel, spark, and timing the engine will run. The
first thing I check is Fuel pressure, next I check for timing and spark at each
cylinder using a timing light on all plug wires. IF I have fuel, Spark, and
timing there should not be an issue so then I go to things like replacing plugs,
plug wires, rotor & cap as you have done.<o:p></o:p></SPAN></FONT></P>

said and noting the work you have done it really does seem you have eliminated
all possible problems except a vacuum leak and a compression test. To me the
most often correct answer to your particular symptoms is timing. I would double
check this one more time making sure the EST wire is disconnected and the timing
light is on plug number 1and also try it on plug wire for number
4.<o:p></o:p></SPAN></FONT></P>

style="FONT-SIZE: 12pt">I am stumped!! I put a brand new MCoy engine in my truck
two years ago and it ran fine until I ran the truck almost out of
gas. Shortly there after one of my new injectors stuck OPEN so I
replaced it and all was well. The following year my son tj noticed that the
knock sensor was broke..must of happened when the engine was put in by my
brother n law. So tj put a new sensor in and the truck would hardly run so
he checked the timing and it was at 40 degrees advanced and yes he unpluged
the wire in cab first. He reset timing to zero and truck idled fine. Now if you
drive it like an old lady it runs ok but as soon as you give her some pedal it
runs terrible. It backfires and misses.We put in new plugs cap and rotor then
drove it for a while and rechecked plugs and they looked good.We also rechecked
fuel pressure and it was fine.. forgot to mention the old plugs we replaced
had to wide of a gap which could of been from detonation we suspect, but maybe
they were not gaped right when put in. Never heard the motor pinging at all
tho. The truck has not been driven much so the motor has maybe 1500 miles
on her and was never beat on. We still have to check the injectors with tjs noid
tester to see if one or more is sticking. We wonder if the distributer is bad
cause it was the only thing I did not replace on the motor. I bought all new
sensors before motor was put in.Also plugged in code reader and all was good.
But come to think of it me and the kid seem to think the old motor with a bad
rod had more snot to it but hard to say. Could my computer be bad?? Anyone have
any ideas what could be wrong? Also forgot to mention that the motor revs fine
when sitting in park, , No miss.. Idles a bit rough but it does have a
cam...almost seems like a slite miss at idle but could be the cam.. I AM AT THE
END OF MY ROPE WITH THIS MOTOR..KEN.....<o:p></o:p></SPAN></FONT></P>
