Ok I just bought an 05 tib gt 5spd, its got 60k on it and no mods,

The problem is i have a lead foot and love to race my friends, well a few of my buddies own acuras and started running they're mouth about the car so i did like an e-brake stand and shut them up,

Since then some weird stuffs been going on, I cant bring the car over 5-5.2k rpms without it cutin out, now everyonce and awhile it allows me to bring it up to 6.5k rpms (factory redline)

When the cars not in gears it will redline, but as soon as i put it in gear it'll only go up to 5-5.2k

Also keeps throwin the same CEL, p0501 Vehicle Speed Sensor Range/Performance, throws ther code twice but on says pending.

Any advice would be great thanks
