good evening all,
first off i have a 2004 AWM 5spd, no performance mods yet
a few days ago i installed a new south boost gauge, everything went fine, testing it that day ran numbers like 10-11 from low revs and ~8 at high revs
same with the next day.
day after that it would only boost till 8psi from low and ~5-6 from high revs.
looked at the T fitting and the gauge end was a little off, pushed it back on, tightened the 3 sides. boosted to the norm rest of the day
yesterday...same problem, max psi was 8. tried fiddling with the whole nylon hardline of the gauge for about 20 mins and it didnt seem to be stuck on anything. everything seemed fine. wouldnt boost past 8 or 7 for the rest of the night.
this morning, while driving to school, same thing, wouldnt boost past 8. then an engine light came on. immediate fault was the "cooling system performance" that ive been getting everyonce in awhile(ill get to it later
) and a 'pending fault' for a cylinder 2 misfire :icon_eek: . so this made me think it had to be a vacuum leak somewhere,
got to school and checked the L hose and anything else i could, didnt fix anything that i knew of.
when i got back to my car(in the rain) and drove home...its boosting till 10 again, whole way home. wtf?
whats going on, im pretty positive i didnt push anything tighter together, and i dont want to bring it to a mechanic , cause my luck it'll boost normally when i do haha.
could the MAF just be dirty? or need replacing? or any rain-dependant vacuum leak?
any help would be awesome
