Whatever is wrong with my car ,its getting worse!?.

going home today ,after driving about 15 mins it starts running a lot rougher and spluttery like never before?. I dunno what I'm going to do, I have no mates I can borrow an AFM from to test and no money for a Dyno run.

It had a tiny hesitation when I bought it,after changing the plugs a few weeks ago the hesitation got worse and its now running worse than ever?. Whatever is going on it gets worse the longer you drive.....exactly what my damn 180SX was doing!! ,I can believe I now have another car with exact same problem!

I swear I'm cursed
