Alright guys! last night i did an oil change and change the FILTER...and WOW can you say FAULTY oil filter ?! The same stretch im hitting 148ish mph now!!!! I stopped after, check how the engine was running, it seems like piston 3 or 4 is misfiring.. ill have to check the spark plus there later today --and lol my o2 sensor wire blew off...weird...very weird.....anyways im going to report that to my mechanic..and fix the spark plug, see which one is bad. After i think i might change tranny filter--maybe if i do that ill gain those other 7 mph that i use to hit!

ps. its hella weird.. im hitting that speed now and my rpm is LOWER!... wtf ?
Check your emergency brake.


Never drink & drive...Ya might hit a bump & spill some !!
