These are the codes
I also have 2 codes from my sfter market cams and a code for an o2 sensor. But that's my normal cel. Bc of the mods
24v 2.8l vr6. 02.5 GLI
Cars throwing codes for random cyl misfire and individual cyl misfire
No blinking cel
New plugs and coil packs(month old)
Car idles fine and runs fine till I get under load, or floor it
But an example of how it's running. I can usually pull up any hill in 6th gear at 2k rpm's. Now. 3rd gear floored. Barely goes up hill??
I'm thinking the same. I just picked up a fuel filter and I'm praying to god its not injectors lol. Carlisle's next weekend.
But I also discovered. That if I ease into the throtal it will rev to redline with no issue.. Soon as I floor it. It has a miss like. It's not getting enough fuel.. Alsp under heavy load like if it was to be sucking more fuel it dors it.. So I'm starting with a fuel filter
it sounds like you have a lot goign on there.. did this all start after all these mods or where driving modded then it happened..
I have a tune, exhaust and intake.. I added a 4.0bar FPR a few days ago and my car runs a hell of a lot better then it was..
I remember reading this a while ago too, http://forums.vwvortex.com/showthread.php?1023665
I would try new packs.. I got my last 2 coil packs @ the dealer for $19.50ea, but it would of cost me $40ea there.. I get good deals @ VW.. long time customer I guess. lol
you could try new packs from VW or even GAP..
Ya.. I always had in the back of my mind that it was the coils.. I hope it is.. That's cheaper than injectors.. Etc..
I got the dura last originally just to see if my oem's were bad.. And just never got to buy oem.. I know I'm pretty sure I'm gonna return all 6 and grab new ones under warranty. Just to see if that's the issue
Ended up putting 6 new coil packs, 6 new NgK double platinum plugs, fuel filter, new oem fuel pump, fuel pump relay.. And was in the process of pulling my fuel pressure regulator off.. When I realized the one vacuum line was off of it.. Which explains running rich and why it ran good at high rpm. But bogged out at low rpm and under load.. Lol makes me mad I spent all this money.. But atleast everything's new.. My 4 bar fpr will be here tomorrow.. Just gonna throw it on too..
Lesson learned this week... Lol. Check for vacuum leaks!! Ha
I am here: http://tapatalk.com/map.php?vud4sx
but honestly I have run 3-4 tanks already.. Prior to the 4 bar getting around 23-25mpg....
now after the 4 bar I am gettting 28-30mpg...
the power is smoother and the warm stall is not as often now. this mixed with a cat-back, CAI, UM tune and lighter flywheel I think have balanced out my car to the way I would like it to be on the highway...
so for the $50 I spent on it from BFI, I feel it was well worth it..

Yeah MPG increased a bit and the power feels smoother and more refined... maybe like 3hp...
I don’t know how your tune is but with UM I was feeling like a skip in the power around 6k, like a hesitation.. I put on a new fuel filter and it still felt the same, so went to the 4bar and that skip/hesitation isn’t there anymore..
overall its awesome!
I would say about 80% Highway... I do 500miles a week.. (roughly)
Thats funny ****, cause I was filling my tank up @ about 315 miles which would be about a 1/4 of a tank when I fill it...
the last few tanks I am not sure what I have done per tank yet.. 1 tank I left my radio on and let my battery die, then the next was me switching my wires for my radio to the switched hook up on the fuse panel and it reset my miles again..
This tank I should be able to give you a much more accurate number.. but I cant tell you I put 145miles on so far of "spirited" driving and only used a 1/4 tank, Oh and plus a can of BG 44k...
Yeah I saw that post... Really we don’t... but I benefited from it... you will get mixed answers on that.. Even if you call the chip manufacture they will tell you its not needed..
I only ran it after reading that link and speaking to a few friends who run them..
but this is up top in the DIY/FAQ
