94 Buick RoadMaster Estate Wagon LT 1 issues

[Bentwings]

Well, good news for a change.The new MAP sensor got the vac up to a little over 16 almost 17 inches. Then adding tested and known good O2 sensors got it just over 19 inches at idle. My son says it runs much better. He is going to put a few miles on it tomorrow and see if it cleans out a bit. Then they will put the scanner on it and record where we are at. I’m curious to see what the new O2 sensors look like on the scanner. The air cleaner only has a few miles on it so I think we’ll leave it alone.

I don’t know if they put a fuel filter on or not but I think it would be a good idea.

If all goes well I’d like to fix the right exhaust pipe. It looks like it got hit by something backing up. It hangs down too far and looks terrible. Not a big deal but I just don’t like exhaust pipes that face the wrong way. I really hope it’s finally fixed. It’s going to get brutally cold next week and more snow. The el Camino is just a handful in the snow that I don’t need.
They are going to try and bring the car to me then take the el Camino back and fix the idle, change oil and a couple other fixes I’ve had to delay.

So that’s it for now.
I want to thank everyone for all the help and tips and tests. I hope this finally fixed this car. I’ll know more
tomorrow afternoon.

Byron.

Looks like 2-cycle-john is out of a job. Failed miserably in his work. Didn't even find a single vacuum leak, and you guys found them all. He is so fired. No worthy of his own scan tool which would have told him about an inaccurate MAP sensor reading KOEO.

I’m bending over ready for the butt kicking. My son drove the car around quite a bit today but it started missing again. He parked it in his shop to cool off. After a couple hours he tried it again. It started right up and ran fine for about five minutes then started missing. So he shut it off and let it sit for awhile. Grandson noticed AF leaking all over. So they raised up and it’s pouring out of the “new water pump”. So they pulled the vacuum lines off the Opti and AF drained out. They blew a little air through it gently then started it without the lines. It ran fine but water was still pouring out of the water pump.

Give me a boot. I had a new WP install so it would not be a problem later. Supposedly a new old stock Opti too. Looks like I got taken to the cleaners. I told them to take pictures before they fix it. And take a scan from cold start until it starts missing. I need the car and I’m out of time. I’ll deal with the other guy Mon.I know...ya all told me there were issues in the manner the testing was going.

I need to go outside and cool off. More later.

months of diagnosis work that starts with 'it can't be _____ i just replaced that' ends with 'it was the ______ all along'

Time to make 2-cycle-john's shop public knowledge, so we can drop off small bags on fire on his doorstep. It's standard proceedure, you know. Sounds like he didn't replace a thing.

I’m back...now don’t every one run, I’m not contagious.

New water pump and Opti. Supposed to be good stuff.

I continued to explore solutions and come up with several.
Install piece of brake line in WP weep hole and JB Weld in place hook pierce of rubber hose to direct Leakage from OPTI. Im
Sitting here in my boat and it’s 5 deg outside light snow. Not that I don’t have anything else to do.
The second thing is to put a thin layer of silicone sealer around the cap joint.

I don’t have these parts in my hands so I’m going on other’s descriptions. The experts are here so is this the things to do?

I’m going out to my son’s shop this weekend to look at this mess. Fortunately he does have some experience with these things and is pretty good at repairing things to work right and for a long time.

He was going to take pictures tonight so I may have something to for show and tell soon.

For the H2Opump, many from the ImpalaSS Forum would install a zerk fitting into the weep hole with a rubber hose to do the same thing.

As for the Opti-Spark, there are several things that can be done. Since the ISSF got 'upgraded' with xenforo, their search function doesn't work well, but I found these with duckduckgo:

A strip of scotch tape joining the Opti- to the -Spark works pretty well, it's what I'm doing. Some ISSF guys use a very thin bead of sealer, hopefully it'll come apart when it needs to.
One guy even went so far as to paint over it with some kind of blue coating that easily peels off.

Don't forget about protecting the electrical harness on top of the engine, as well as the connector that goes directly to the top of the Opti-Spark.
