so it started today....... i was driving down the street and my 01 1.8t w/ apr 93 oct programming, as i hit the gas it was going towards the 20 mark, then it drops down to 10, then back up to 20......kept doing this till i got off the gas

only things i have changed and not had this issue are boost guage and some vac hose(crp 3.5 x 2) from ecs tunning......... maybe my dv hose popped off, and i will check that tomorrow, but anyone else think of anything else?


could it be my n75 going bad?

 

do you have an intake? try cleaning the maf. and you have an 01 so if u got vag-com log boost and maf readings. see if you notice anything.

 

well if it was loose hose then it'd be low boost all the time, it could be the n75 or boost controller if you have one. also check the lines to the boost gauge

 

everything up top looks good....... not low, just when it gets to, and now it is 15 psi, it drops real quick to 10, then try's to go back up........ could it also be bad spark?

i got some comming, and the ones i have are hella old


will definatly check dv hose, hope it's not n75 as it is just maybe a yr old
