Did a lotta work today, now SYS
I tackled a PITA project today. New injectors and new valve cover gaskets. Hard to do when you refuse to disassemble much at all. 
But the new injectors solved all my stumbling, stalling, and flooding issues. runs like a top now! No more leaky valve cover, either!
But now, even though she runs perfect, I'm getting the flashing SYS. Flashes twice, then gives me back my oil temp, then waits, and flashes again. Ideas?

Probably is low voltage. Pull the codes...... http://www.c4guru.com/articles/CCMCodePull.pdf ECM code 53 is a system voltage error

Sorry, it was late and I was tired. 
She's a 92 LT1.
The voltage by the monitor is still +/- 14.5 volts while the car is running.
Wouldn't a low voltage issues be something unrelated to the work I did?
Though there was a minor shorting issue when i accidentally dropped a wrench. Thankfully, both 10 mm wrenched that were lost did come clanging out eventually.

Ok Ladies and Gents, here's what I found out.
Module 1, CCM, flashed four codes:
H31: LCD Data Circuit Error
H33: Data Clock Circuit Error
H35: Data Strobe Circuit Error
H37: M Clock Circuit Error
Module 4, ECM, flashed 1 code:
H28: Quad Driver 3
Still trying to figure out what they all mean, but I've got the FSM out and I'm looking, though if any of you have any insight, let me know.
I was able to clear all the codes, drove for a bit, and nothing has come back, but I'll reserve saying success for a few more starts and stops.
