78 Rabbit, CIS, 1.6L

Facts:
*Doesn't "do it" when it's cold.
*Seems to "do it" when under load most (going up a hill etc).
*Sputters a small bit while at idle, there is a 'hic during idle that is rhythmic.
*WOT leads to TONS of hesitation but car does eventually accelerate.
*Is worse at times but less at others.

What I've done thus far that's probably not related:
*Replaced fuzebox.
*Replaced sparkplugs.
*Replaced wires.
*Replaced cap/roter.
*Replaced oil.

What i've done in trying to fix this or like issues:
*Replaced primary fuel filter.
*Replaced fuel pump.
*Replaced thermal timing switch.
*Replaced injectors/seals.
*Replaced warmup regulator.
*Replaced Air Filter.
*Cleaned Fuel distributor.
*Replaced all available vacuum lines and everything is now hooked up!
*Timed the vehicle.

...about the only thing I haven't done is the EGR.  Duff mentioned it might be a mix issue on the fuel distributor?  Fuck, I've always been scared shitless to play with the mixes on there. 

Does anyone have any ideas?  I've quite seriously built this car from the ground up and would so hate to have to bring it into a mechanics shop to ask for help :(

Hahah, thanks!  Good advice, but I think I'm going to stick with slipping GHB in her coke and waiting till she's asleep like I usually do.

CIS meter air boot and TB boot?

I haven't changed the cam timing, do you think that it could just "meander out"?  The car wasn't doing this issue a couple months ago.


I suppose that's a possibility.  They look good but leaks could be anywhere.  I have spares so will swap those over.


I didn't cause I replaced them when I started work on the car, who knows, I'll check em again!

Thanks a bunch for the responses guys!!!  My adventures into "non-carb'd land" have been treacherous!

The contact points?  Replaced.  The boots?  They aren't new but they are much newER and look it externally. 

I got this post to my same query on the whoretex:


It's pretty much GOT to be a vacuum leak at this point as I've replaced/fixed most everything having to do with fuel.  The rationale sounds sound.  I'm going to swap the boot first then think about deleting my EGR and check the auxillary air regulator...

Roger that, I'm a FI newby :).


That's what I figured you were talkin' about.  That's a quick fix, I'll swap those when I get home and see how it goes.

Swapped the boots and EGR, problem persists but is less.  I found a gaping hole behind the boot at the TB so I'm sure that was part of it.  Car doesn't lurch as hard now - it's just a super bad sputter that doesn't allow me to accelerate or run right still - when warm (which is super frustrating since the car runs LIKE A FUCKING DREAM when it's cold).

Perhaps it is Timing.  I must admit - I don't fully understand how to be a tooth out.  You mean on the flywheel/I'm going to have to pull the trans again, rotate the flywheel a couple teeth and reinstall?

Alright, that makes more sense.  I did change the warm up regulator.  Yep, only when warm, man it's frustrating.  I'll hit it again with the timing light and then try to make sure it's not a tooth off (Bentley here I come).

BTW - it was a RIDICULOUSLY awesome night last night for riding the bike
