Ignition Miss-Possible Problem with Plug Wire
I have been chasing an ignition miss for a couple of weeks now and ran down the usual list of potential problems. Today was spark plug wires. I have an over-the-top system and this wire was resting on the A/C compressor. I anchored it there with some Goop. The innards were laid bare. Am I on to something? Just kidding. That wire has been replaced. You just never know until you go through points/condensor, dwell, timing, and so on.
*Edit* - I am putting in a new NAPA/Echlin coil tomorrow just because I want to. I have my moments.

I will know this weekend. Too many things happening now other than the Corvette. I'll put the new coil on tomorrow and hope for the best. New R-45T NOS plugs are coming in on Monday from Michigan. That is my last resort. Could be game over for 2015.

Plug wires are not a $130 an hour project. DIY- a six pack of your favorite beverage and a sunny afternoon. One at a time. And a coil is not going to help that plug wire unless it's a coil that has a secret life as an arc welder.

I replaced that wire. I have basement spares.

If someone could find an old working SUN Tune up Tester for sale, they could be one of the most popular posters in vette land.
"back in the day... Sonny, it took longer to hook up the machine than it did to find the bad cylinder".

I have one of those old Sun Tuneup Testers. Nothing replaces a good visual inspection. Nothing. It will give you loads of information if you know what you're looking at. Without the visual inspection it's a waste of time.

All fixed now and good to go?...

Back to you tomorrow. Not good tonight. Even with the new coil. But I have been lazy. I did not pull the #2 plug where the bad wire leads to. It may be fouled. But D*** it is hard to get to with that A/C compressor in the way. So up we go with the three-ton jack and jack stands. I am getting too old for this kind of work.
Might be C5 or C6 time.

I admire your humour! In 30 years of driving these Tupperware cars I have never owned one newer than 1979. And really I would probably never go newer. I am just very frustrated at the moment. But that will pass...somehow. D*** I can't find the problem!

Your a funny man Paul. U havent seen a late model repair manual. Yea its a $300 manual that looks over a 1000pages in several volumes. Or looked at a EFI data log to tune and troubleshoot. U would miss your old carb and distributor fast. And now u have 8 coils that can fail. Nearly every ignition and fuel system part is $300. Injectors, fuel pump, Power Contol Module, mass airflow sensor. All new science and might be fun for electronics engineering student but for yourself u may need a dealership close by.
Anyways u might be surprised u have a mechanical problem. Burnt vlv, bad vlv spring, wiped cam lobe, bad timing chain or timing set, even an intake/vac leak.
Im staying tuned as this is getting interesting.
