Matt mentioned the labor involved, so I opted to go ahead and replace the unit and water pump even if it is only the cap itself now. Especially if we can keep it dry, just don't want the chance of needing to replace unit short time later, and have to go the labor again. Roll of the dice, but...

Looks like it'd be quite a job to get the cap off.

Thanks again for all the info. Pretty sure he knows his Corvettes. He owns one and works for a local dealer specializing in them. The labor is 5 hours @ $50 per hour, less than half the dealer rate. Good price for me, good for Matt who's happy to make a few extra $$. I said about 1K, OK so it...

OK, here's the update. I was wrong on the wire diagnosis. Double checked and had been looking at spark from another wire. Anyway recheck with a new wire and #1 still wasn't firing. Nursed the car to Matt's and he just called with the bad news. It's running on 5 cylinders, he was surprised I made...

Thanks all. Out of curiosity, I pulled the passenger side #1 plug wire and to my surprise , no spark. Not to jump to a conclusion about bad Opti, I pulled wire #2 and put it in #1's position in the Opti and spark plug, and voila, sparky and strong, albeit engine was barely running on 6 cyl...

Thanks everyone for the input. I'm in a time bind, so it'll have to go to Matt, our Chevy tech. I will however post pronto when I have more info. And I'll try to get a FSM, now that I know what it is, LOL. These acronyms, gotta be a youngster sometimes to keep up...Duh for me

Thanks, Paul. Maybe we'll meet up at an event in the future. I read where the pre 92 models were vulnerable to injector cleaner, something about the o-ring composition, 94's aren't supposed to be affected, and it was immediate, so I don't know if they would have deteriorated that quickly. That...

As to the miles, about 66K

I've never wet the engine, but I've only owned it for 8 months, could have some past corrosion I suppose. Hasn't thrown any codes. Have my doubts about the opti because it worsened suddenly after the increased octane and fuel injector cleaner. Due to that I suspect Oxy Sensor. I talked to a...

I was running 87 octane in it and for awhile had been having a problem when pulling in higher gears, more noticable when warm. I picked up some Gumout injector cleaner, hoping if it was water in the tank that'd dry it, then I went and filled up with a tank of Chevron 93 octane, containing 10%...
