Took it out for some miles this morning. It is the A/C, compressor I assume, that is causing the bad running/surging problem. With the A/C off, the car runs fine.

Sounds like stray voltage or electrical noise.  When I first installed the GEN IV AC, I tried to cheat and use one big accessory wire from the dash to the battery in the trunk.  All ECUs, ECMs, processors, computers, etc. need the 12+v (red) wire needs to be a  home run to the battery.  Multiple processors on the same 12+v wire can (and do) pick up noise from the other devices.  I had two devices installed.  Vintage Air and MSD 6AL cd ignition box.  The engine ran like crap and the AC didn't make any sense.  Turn the AC off and it run just fine.
I separated the 12+v and ground wires with home runs to the battery.  AC worked and engine ran.  I later relocated the MSD box away from the VA processor.  Now, every new gadget with a processor has its own home runs and space away from other processors.

Thanks for the input. The A/C does have have runs direct to the battery. This is a new issue that hasn't reared it's head before. The shop I had it worked on is going to have a look next Thursday. BTW, it does not seem to affect the engine at idle, oddly enough, which is why he didn't pick up on it in the shop.
My main computer for the engine is actually pretty close to the A/C. I'll have a look to see if I can move or shield the A/C processor, I actually don't remember where it is. If it's internal, there's obviously nothing I can do about moving it. I'm sure not going to rewire the 95ish wires running to the computer, and it's about the only place it can be without a major major project. BTW, the wire bundle running to the computer from the televork patch panel, as well as several individual bundles, are shielded.

One of the things I do when powering electronics is wrap the lead wire with tin foil.  Doing that is a real pain in the you know where.  I cut strips and wrap like it is tape.  At the source and at the device a ground wire is wrapped around the foil and a terminal to secure to chassis is screwed down.  I do apply a little dielectric grease to the ground wire before tapping it up.  Then the whole run is wrapped up with a good plastic electrical tape.

Now having said that, this has been done for tacks, speedometers, radios and ECMs with no side effects.  Never had more then two sensitive electronic devices at once and no experience with VA IV system.

Yes, Bill..many years ago you showed me how to shield wires. The sensitive engine control wires from Ron Francis come already shielded, but I did wrap my big wire bundle from the patch panel to the computer just as you instructed. Not really sure why this new issue would come up now after 4 years if it is a shielding/interference problem, but it sure makes sense and something to look into.http://57fordsforever.com/smf/index.php?action=dlattach;topic=3750.0;attach=12253;image

Rich, what is the weather like currently in TX ? Are  you gettin alot of rain and dampness ?
I have had mad experience with dampness and electrical malfunction.

RICH MUISE

We have had lots of rain, but humidity is always low here. Humidity rarely gets into the 40's even during/after a storm. It rained Friday night here, Saturday morning humidity in my garage was 31.
Got my ball joints from Concours yesterday. Look good, made in India. imho, way better than most stuff from China. I'm going to get urethane boots ordered for it, even though if I remember correctly, India rubber quality is generally very good.

I was checking into an ebay ad for a set of Motorcraft coil on plugs.....got an interesting response to my question about whether or not they had a Ford logo embossed on them..........
"These parts are a Motorcraft brand and do not have any affiliation with Ford branding, so there is no Ford logo embossed on these ignition coils.
Please let us know if you have any other questions.
Thank you,

Has something changed with Motorcraft I'm not aware of? I thought Motorcraft was owned by Ford. The old ignition coils I have have Motorcraft labels/stickers, but also have the Ford oval embossed on them. I'm suspecting a switcheroo

From the owners manual:

When I was 14 years old, I was amazed at how unintelligent my father was. By the time I turned 21, I was astounded at how much he had learned in the last 7 years!

That's what I was remembering. Thanks Joe. Reaffirms my thoughts about the bait and switch tactic.

Dropped my '57 off to the shop that did the A/C work last Thursday. Told them there was no rush as long as the car was inside overnight. They finally had a chance to look at it today, and got it fixed. It was a simple overcharge causing the compressor to shut off and on. No charge. Yay!!
Funny, I had them recharge my Subaru last week also, and when I picked it up, the guy's wife told me he broke a plastic piece on the dash when he was replacing the cabin filter. She said he found a replacement and they would cover the cost. I didn't ask which piece it was, and couldn't find anything broken that wasn't broken before. Today he told me the piece was in, and I asked whaich piece it was. He said,  "to the right of the shifter, the wood grained piece". I said Josh, that was already broken. I was happy as a pig in dodo at the no-charge for the '57, and insisted on them letting me pay for the parts he found.The salvage yard told him he should buy both sides, which he did, because the grain patterns and are all over the map from different cars. I like the new pattern much better, lol. Now, if I can get the dang things in without breaking them.

That sounds like a reliable business a good deal for you Rich. It is also great to work with honest people.
I am thinking that I might get my 57CS inspected next week or so. Nothing going on here in shows or the like, but it's time to get it out on the road again.

RICH MUISE

"on the road again" is always good,........... and also one of my favorite songs. It's the first song on a CD I have, so easy to cue up at the appropriate time, lol. I've been doing some road trips the past few weeks, but not in my '57 until I get the ball joints replaced. Hopefully early part of next week.

My '57 is at my buddy's shop for ball joints and related stuff. He got tied up on a car he was working on, so couldn't get to it today..hopefully tomorrow, then an alignment.
Going to check next week to see if it's still on, but a car show I've wanted to do in Mena, Arkansas is in 2 weeks according to an ad in Hemmings. That'll make for a nice roadtrip. Small touristy town in the mountains. The Mena website says it can get very hot in August with temps in the low 80's. lol. It was 104 here yesterday. Only 94 today.
Got a call from our roofer today, and they're having supply problems with the shingles. The color we wanted (same red as what's on it) won't be available until January at the earliest due to the company that supplies the granules for the shingles being shut down due to the virus. Who knows what they'll be looking at delivery wise when January comes around. He's checking on availability on what was our second choice.
