alright so i've been having a few issues with boost/hesitation.. after i've been driving the car for a while, highway or not, (maybe like half hour) i start to get spells where if i let off the gas slowly or hold it at a low throttle position, it feels like the car has kicked into neutral and starts to slow down until i either let off the throttle and give it a stab, or floor it for a few seconds...

now i'm thinking it's the wastegate sticking, but i want to be 100% sure before i attempt to replace it or fix it if it's even possible... my dad kept muttering something about fuel problems, but i'm pretty sure that's not the issue, as i've changed the filter and gone through a tank already. i guess my question would be is if it's practical to attempt to replace it, or try to fix it... it'd be nice to have everything working 100% before i start the bolt on marathon, just to be sure you know. any suggestions?
