I still don't understand why you are even looking at anything beyond the stuff you messed with at the outset. For that matter, I don't understand why any mechanic wouldn't start there either. I mean, it's not like replacing the fuel lines blew a hole in your muffler, right? |
Muffler has nothing to do with it. My comment about getting a new one is because I simply want to. I am waiting on new fuel rails coming in the mail. I may have knicked them up quite a bit when I replaced lines. The real question is, what else can I check? My next step would be to pick up a meter to test the ground wire on o2 sensor but like you... I have a feeling I botched something during fuel line OR knocked something. I'm idling it my van right now... lord she sounds like complete shit but gotta swing by grocery store. Also, to help you understand, I wouldn't even call myself a mechanic... I am someone trying to 1) save money 2) learn a new skill. Not the sharpest tool in the shed like some. Working on that. |
My MIL was a heavy lift crane operator while my wife and one of my SIL's have driven or are still driving heavy equipment for a living. |
I admire women who do FUN things like that for work. I hear those crane operators make good money too! My dads building a house right now and he let me drive the little tractor around, moving dirt for him hehehe

Oh, that’s no good.
Maybe time for a set of those fancy new injectors that someone’s selling here. |
I bought a brand new one from this awesome VW parts shop up the street. I couldve found one cheaper (with a core) online but ehh, I like to support the local small shops (I am a small business owner as well). Thanks for reminding me that The Samba has parts for sale!

I just want to chime in that some people have the natural Ability to learn to troubleshoot stuff. I can tell you to ignore the folks who aren't respectful of your abilities, you are a natural.
Protect those hands with nitrile gloves always
Have you reached out to one of the mobile guys about taking some time to go over your ful injectors? That missing pinhole is definitely a problem |
You know, Ive reached out to TWO guys on VanAlert and both ghosted me. Oh well. This may sound dumb but what else do you think I should go over in them? Thanks for the compliment by the way. I am actually a very slow learner, and not too detail oriented (obviously working on the latter). I was talking to my brother yesterday and he said that he has recently become his own mechanic as well. His house along with two vehicles burned down in a bad house fire earlier this year, so he started doing his own repairs to save money (he has three kids, they lost everything). I know my dad is really proud of me F'in around with my engine, lol. Thats what matters to me the most. Just want my dad to be able to brag about his kid(s).
I will be installing the rest of the new rails and new injector this wednesday or thursday. I cannot wait!!!!!!!!!!! Then I can brag about my van, and the inside garment rack my husband made for me  ... till next time...

Would love to hear how this saga ultimately turned out. I too am troubleshooting a possible stuck or not firing fuel injector. Extremely rough running engine. Found no change in idle when I removed plug wire #3 or fuel injector wire #3. Verified spark is working and swapped fuel injector wires to verify wire is working.
Problem started immediately after I had my fuel injectors cleaned. Cleaner says that maybe somehow the injector is stuck and suggested I tap the metal part of the injector body (while the engine is running) to break the valve free.
Unfortunately, that tapping did not work. So I may try a can of snake-oil fuel injector cleaner and running the van long enough for everything to get nice and warm. Then maybe some more tapping.

If you dismantle a VW engine and reassemble it enough times, will you end up with enough extra parts for another engine? |

Hmmm
Is the cleaner local to you?
Even if he isn’t, part of the cleaning service is testing the injectors for flow and spray pattern.
No way should they return a cleaned set to you with their operational state an unknown.
Pull them, take them back and have their operation verified.
Tapping on them? That’s just stupid!

Hi there! I really should have updated this post with my findings. One of my injectors was missing a pin! Even after taking it to a mechanic (who claimed that there is "no way to check the fuel pressure in these cars" and gave me my van back with the *exact* same issue. All he did was replace the coolant temp sensor, charge me $250 and send me on my way 🙃. This helped nothing). I pulled the injectors again and finally noticed the tiny pin was missing from the tip of one. Picked one up for $50, put it on and bam! Like a new car!)

Well I finally got around to testing my fuel injectors and they look great.

I admit that I'm no expert in what a fuel injector pattern should look like, but I'd have to say the top one looked like more fuel than the bottom. Also, both might look a bit more "squirty" than "misty" to me.
I suppose I'd need to see what known-good injector spray patterns look like for a better comparison.
Here's a link on testing for flow volume. (Not pattern.)

Sorry to hear your local shop didn't know what they were doing. 
I'd recommend Quality Auto in Whittier. Jerry and Carlos run the small shop there and are great. The only place I have work on my vans aside from me. Jerry is a Vanagon specialist and a Vanagon owner and his son owns two! Carlos has a beautiful bay window bus. Not as close as you'd like, but not too far up the 605 freeway from you.
