Car revving up on its own

So for all you enthusiasts, I recently joined this forum, but I got a huge question. Why would my car rev up to 4000rpm and just sit there and bounce? I just rebuilt my engine and it threw three codes. MAP P0108, TPS P0122, and VTEC P1259. What's the deal?

Well at 4K rpms is where vtec would kick, so there's definitely an issue there. Sorry I can't be of any more help.

Re: Car revving up on its own

Yeah which is why I'm scratching my head over here. I had a buddy say check my wiring but all that clears inspection. He said maybe unplug the ecu and plug it back in and that might clear the issue, but I haven't found where it is yet

Undoing the battery for about 15 minutes or more will reset the ecu also.
