Fuel pressure regulator , located on the fuel rail. test it to make sure it holds vacuume

 

Cool, you have a Vag-com, now purchase a Bentley manual, it has all the sensor test.

Here is what I want you to log.
Block 115, do a WOT pull in 3rd to redline.
Block 003 same
Block dam, I cant remember, it's the O2's do the same.

Do each on separate, to get the best resolution. After that email them to me, & I'll graph them, it will give us a starting point.

 

yea i know what a ripoff right? now that i think about it, they're not ngk, but some denso iridium plugs. i was assured that they would help with the problems that come with running high boost...i guess they do. whatever.

 

Denso plugs are the wrong plugs for our cars. A near by mechanic uses them and we can tell because all of his costomers have come to us and we pulled Denso's out of every car.

 

LMAO - when I read the thread topic - i thought u saw my car or something...



yeah - Bosch plat. are good to go, no need for colder plugs unless u
start getting serious mods..

 

so if i replace the densos with boschwill it run any different? could that be the cause for my knocking issues?

 

Take off your MAF sensor and clean it. Grab a zip lock bag, fill it with 90% or higher alcohol form the store, put the sensor in there shake it around for a min, then let it sit there. You'll see particles start too fall off. Air dry, then reinstall. See if that works

 

i bought a new one, it did nothing.

 

Honestly. My boss gave me the bosch spark plugs he puts in his 911, and I did notice a difference.

 

ok so it turns out one of my intercoolers had a crack in it. i replaced the stockers with a front mount kit, came out awesome. it was running great until the other day when something else broke. not sure what it is, but when it starts to get into boost, the motor misfires terribly and the check engine light flashes. sometimes its just a hiccup, but other times it feels like its running out of gas (like a few cylinders are dead) and the whole car shakes. it seems like it would be a flaky sensor, because it will rarelypull hard under boost without misfiring. any ideas?

2ks4 - i tried to hook up my vag com and get those measuring blocks you told me about, but i guess i have an unregistered version or something because it doesn't let me see those particular blocks. where can i get a good copy of the software?
