Runs bad.

2006 225 VZ225TLR
First what's the fuel pump pressure supposed to be? I test it and it comes out at 55#
Comp 120/6, spark ok.
Start it and it idles, when put in gear and accelerated it revs up and down fast again and again and will smooth out when put back in neutral.
Does it every time shifted into gear.
What should I look for?
Thanks

TPS???
Checking the tps and it shows 5 volts into the tps.
From what I understand it's supposed to be .5 volts not 5.0 volts
What would cause the voltage to go up so high?
That's probably the reason the motor runs bad(see other post).
Thanks,

TPS showing 5V, first make sure your seeing the wiper side and not the reference side. Ref side will be 5V, wiper side going to ECM should be .5V or so.

If reading correct pin then look for bad ground
