I just tried WOT in 5th at 3k, and my speed didn't increase nor did my rpms. Sounded like **** though. I never go WOT, so I have no idea if this problem has existed...

Is this the MAP sensor connector? I just installed an oil air filter so I hope the MAF didn't get screwed up for the filter...

Also, does OBDII give any information when no codes are visibly being shown? Basically, what I'm asking is if I bought an OBDII reader would I be able to diagnose this?
