Ok driving home from work today and decided to give a quick pull on the highway and ran through 3rd. Half way through it felt like i lost power quickly and exhaust sounded off. Almost misfire type feeling. Under normal driving and acceleration everything seems normal. Oil pressure looks good. At WOT my AF gauge was a tad on the rich side even though i know autometer gauges arent completely accurate. I let the car idle when i got home and looked behind the blower where one of the pulleys was squeeking. Noticed some play in the pulley right behind the head unit. Could this cause the problem? Im most likely gonna pull the car in the shop fri and do a compression test to be safe. Could it be out of tune? thanks guys
