You won't be the first to have issues with FIC Injectors.

You know for the price,he does back up his product and he will replace the injectors till you get the right ones that work what FIC
doesn't understand is the labor and $30 gaskets it takes to change the injectors each time.

Accel Injectors are brand new best bang for the buck.

You can run the stock chip just for checking.

That is true,...I am changing to the stock prom just to test them.. I am guessing under normal operation with the stock prom the secondary injectors are not getting the pressure until 3800 rpm.. if that the case the car should run great until then...

I don't want to bad mouth FIC in any way...but there were two seperate installations of FIC rebuilt injectors here in WAZOO land last summer and both had issues and had to be replaced. I replaced mine with the FIC stainless injectors, a bit pricey, but are working flawlessly.

For the last ten years I have been using the same gasket.
I cut it from rubber from an inner tube. It does not stick around
the water jacket holes and seals much better because it keeps
it's resiliency.

I tried looking up the Accel injectors. They don't say if they are
stainless steal or if they are "flow matched" to each other.

And a couple here in FBI land.

Just the thought of having to do the job twice or 3 times, yuk.

Stock settings, if at WOT or more then 94% throttle secondaries are on at any RPM.

With no secondaries the way i set them up is secondary injectors go on with .001% throttle.

I don't think Accel makes the injectors i forgot who makes them, maybe Lucas not sure.

Just to check fundamentals...

is the firing order correct? I wouldn't go too much further until you can trace out which wires go to which coil post.

Marc H did a presentation last year on rebuilt injectors. The problem isn't the nozzle or mechanicals but rather the injector coil which is not rebuilt. Of the issues I have heard of w FIC, they have always been stand-up about backing their product. That's not the issue. But w 20year old injector coils, its a problem waiting to happen. My Accels have ~20K on them without a hiccup. I was fortunate enough to get them when Atlantic Speed still sold them so reasonable price.

I agree with Mike100. Go back to the first start up after rebuild. Has the car ever run properly?

I wonder if there is some fundamental timing or fuel problem that was masked by the seemingly OK operation that was really just the engine running in Ignition Module spark control mode ( I can't remember the correct name, but it means that the ECM is not controlling the spark timing.)

OK after a bit of troubleshooting this is what I have:

with the stock chip in and it idles fine.(although it is running rich on the drivers side),..So I have replaced ALL the spark plugs but no change with the modded chip(have not tried the stock chip with new plugs....

My only question with Jim's post is...the car ran fine(all be it with no power, a little hesitation,and the idle fluctuation BUT NO missing...(the moment I fixed the pin- the car ran like S^&t..all vacuum is checked,...NO codes...

Bottom line its missing and the only thing that has came on line is the secondaries because of the removal of the code #42.

Any other way to check this??

Are the sparks as lively on the drivers side as the passenger side?
It's easy to check with a spark tester or just put a plug in the end
of each wire one at a time. Maybe when under the plenum last a wire
or two got unplugged?
