I can't stand my car anymore....

[spoon!]

Rich ALWAYS comes through

If you wanna be super knit-picky to figure out what it was, go through each wire and test the continuity. I'm (along with everyone else, im sure) curious to see what was the actual issue

I was gonna say to stick a jumper on the CTS connector and ring out pins 6 and 10... just for giggles.

[robocopywriter]

I love a happy ending.

[Project_2501]

Badass!

Nice work mate. The community works its magic again.

[Mr. Knappy]

I love a happy ending.

Depends what she looks like.


I'll eventually check the comtinuity and resistance of all the wires and find out what was actually causing that. My guess is either the CTS, O2 sensor or the potentiometer on the fuel distributor. It wasnt the DPR since the idle went to like 2500 when i disconnected it and i was able to get a reading with the test harness. It would be nearly impossible for a knock sensor wire to go bad since those are so damn thick. These things are technically complexly simple. Not very much that controls the engine. I'm still going to replace the fuel distributor when it gets here and then do a final tune on it. Then we might start on the body and the rest of the interior. Headliner was jus done.

[gtidaddy]

sounds like you might be back

[GTDGLI]

I swap turbo diesels into all our MKII's
Fixes everything

[anterrickson]

Congrats man! Im glad you got it working!

i got pissed at mine now it has holes in the hood

I'm no Horatio Caine but it looks like the hood was off & stood up against something before being shot.

Stick with it Knaps

See, he's back to his old self, pointing the newbs the right way. This was just a minor hiccup

The c-clip goes onto the little groove on the end. Make sure you squeeze it tight or you won't get the gear on. Then you just push the gear on till it clicks. Test by pulling on it. Then that gets installed into the gear box. New ones can be a pain to get in. Takes some patience. I actually used an old O2 sensor socket to lightly tap mine in.

lso agree that a vacuum leak could make it do that. Injector O-Rings?

Nope, the wiring harness did that.

[oldskoolracer]

Glad you got it figured out , been having the same issue with mine and after hours on end and a couple hundred $$ in parts I found that the head gasket was blown. Not mixing fluids, but burning coolant and losing compression through the cooling system

[mk2fu]

glad everything worked out. i bet youre even happier you didnt scrap it now, time to fall back inlove with it! ... until the next problem arises. Good work.

[DSR79]

SEE..........WE KNEW YOU COULD DO IT!!!!

[Run_That]

Glad to see you doing something with this again sir.

[trn905]

...The community works its magic again...

nice to see this in the MK2 forum, a rare thing as of late...

[Mr. Knappy]

Thanks everybody. Drove it like 10 miles today. It was nice to be out in it. Seriously thought it stalled every time it went to idle.

[Soup Guy]

Nope, the wiring harness did that.

Oop. Sorry. Reading is greater than me I guess. Glad you got it working!

[Ice.dk]

hmm sounds funny

i think i could be a hall sender with a bad connection maybe, vacum leak, what about the cold idle does that work all the time maybee a bad thermo switch

[Mr. Knappy]

One great thing about it running good now is that the fuel mileage went from between 14-19mpg to this:



That was the 22 miles drive home from work. Mostly city, too.

[db3ck]

wow thats really good must be nice to see that

[Mr. Knappy]

It is nice but I know it's running a little lean so it will change once the new fuel distributor gets here at the end of the week.

[db3ck]

o cool beans i cant wait till i get my mk2 up and running its gunna be a lovely day when it comes

[under the radar]

my '91 GLi had the same issue. solved it by getting the T-body idle stop/ idle switch perfectly adjusted with a feeler gauge. my car idles perfectly, but if i move the idle switch even 1/2a mm it will get that surging idle. makes me wonder if my harness has the same issue. let me know what you find when you test your old harness.

I'll be digging into it more here in a few.

I took a picture...

[.:R32:.]

This is looking really good!!

[Mr. Knappy]

Thanks.

I think we might have found the issue in the harness. I think. I have continuity between the CTS wires, O2 sensor wires, DPR wires but NOT the ISV. Now, the only thing is, the ISV has a fuse on the fuse panel. Does the ISV run to the fuse panel before going back or what? I don't have the patience to figure it out nor do I care so I will jsut make myself feel like that was the issue.

[robocopywriter]

So wait... the ISV was working but there was no continuity in the wire?
Thanks for posting what you found by the way... hate it when people don't do that.

I think that is because the ISV is powered through the fuse box. Who knows. I did get 12v to it before I removed the harness. I still don't have a clear reason why that was going on.

Anyways, I replaced the fuel distributor and intake tube.





Pretty sure one of the two is either from a Passat or regular CIS-e.

[under the radar]

the one installed on the car is from a passat.

[Mr. Knappy]

I figured. Oh well. It fits and it works.

[VegasJetta]

... And the sunroof bug deflector?

I have two here for you. I will be in Philly in August, I will bring you one if you can wait...

hmmmmm... I wonder about that circuit. My ISV works and everything works perfectly 90% of the time. But it has some random idle problems that come and go.

[Mr. Knappy]

Do it, you won't.

[under the radar]

i think the passat ones have a nicer shape anyways.
