Chasing a miss - 1992 LT1
My 92 LTI developed a miss 2 weeks ago, cleared up after driving about a mile. No issues intil 1 week ago, miss reappears this time didn't go away. Went the spark plug and wire route. Opti is next. Ordered a new water pump and opti. Getting ready for the parts to arrive, I pulled water pump and opti and crank damper. Being cautious, I marked the top of the damper, but in my efforts to remove it, the mark is GONE. Does the damper have to go on the same position it came off ? Working on a 1992 LTI. If this doesn't fix the miss, whats next ? Thanks for any help.

Well, the new opti is going in. Already removed the everything in the way. I can't believe how difficult it is was to change plugs and wires. I removed what appears to be a vintage 92 waterpump (new one waiting to go in). The opti I removed has no name or markings on it at all. If these items don't fix it, I may need professional help, for me NOT the car.

In the process of getting a reverse torx socket Hopefully it will look bad enough to justify changing. Also putting a barbed fitting and diversion tube on the WP. While I'm at it a few new hoses and t-stat.

Fixed !!!
Here's a follow-up for the original post. Many times a thread starts and the fix never gets posted. Well......8 Bosch3 rebuilts from FIC fixed the problem. Aprox 45 minutes of labor, reattach the battery and a quick test drive reveals that my miss or stutter or whatever is gone. I took the long way around thanks to some bad advice from friends, but it finally runs great. It only took new plugs, new wires, new opti, of course a new water pump, a new alternator (don't ask),new tps, new map sensor and a new iac, a bunch of hours of swollen hand, an unknown quantity of Sam Adams and few weeks replaying the options over and over. Thanks FIC (Fuel Injector Connection) for great product at a reasonable price. My neighbor had three injectors replaced by one of the local parts changers for almost $500 w/labor.

Well good work. I hope you held on to that original opti. Some of the aftermarket ones, (not sure what you put in) are less than optimal. You can probably clean your old one up a bit an keep it for a back up.
