My 1996 LT1 (automatic, 67K) has been hesitating upon startup but eventually recovers. Following a long period of driving (>1 hour), it sometimes stalls but usually starts right back up. Yesterday, however, it started then stalled 5 seconds later not to start again. I had to be towed home. I originally thought it was the optispark as the symptoms were the same as what I experienced last time the optispark had to be replaced. That is, a couple of hesitations here and there, then no spark to the engine but with fuel pressure. The dealership does not believe that it is the optispark, rather, they believe that it may be the computer module as they are getting the codes B0054, P0118, and P1115. Only the first is indicative of a computer issue as far as I can tell. Their theory is that the computer is failing to read the key code (even though B0054 is not this specific error) and cutting the spark to the engine. Thus, it goes into anti-theft mode. Obviously, replacing the computer is time consuming and money consuming so I thought that I would reach out here to see if someone can confirm or deny that computer replacement is the best course of action. What do you guys think?
