I sent your message to the Owner of AGCO Automotive he replied back with
this.
Have them verify fuel pressure and volume. It is NOT enough to have
pressure. It must have the correct pressure and full volume.
Hope this helps.

A young man who has made quite a favorable impression on me is having
car trouble, and is asking for help. Being a Shovey gasser, I don't
have any/many ideas, so I thought i'd put it out here and see if y'all
have any ideas and suggestions.

Would love any ideas you can give me on the issue I'm having on my
car('98 Chevy Camaro 3.8 V6). It is misfiring on acceleration, and
fairly badly. The injectors have been replaced, the spark plugs and
wires have been replaced, the heads were recently reworked with a
valve grind, all new engine gaskets, and the Idle Air Control
Valve(IACV) was recently replaced as well. It idles well, but
misfires as soon as a load is placed on the engine, any load at all.
The less the acceleration, the less the misfire, and vice versa. It
is very bad when accelerating in a high gear at low engine rpm. The
shop diagnosed misfires on multiple cylinders, and recommended I
change the injectors and plugs, which I did, and of course it didn't
solve it. I will talk with the shop tomorrow, that's another issue.
Ran a compression check today on all cylinders, the numbers were quite
good, all in the 180-205 psi range, and the minimum for this engine is
100 psi. Suspected the Catalytic Converter of a possible blockage, so
I removed the exhaust pipes at the manifolds and test drove, still
misfiring as usual.
Would love any ideas you have, sir! Thank you.

He is a Navy veteran, so I'd appreciate any ideas to help him. Thanks.
