Default Bad TPS

My TPS is bad on my daily. I don't wanna just get the sensor, I wanna get the trottle body with it. Cheapest I saw oem new is $250. Black Works Racing has one with TPS for $115. I'm going go with the BWR. Has anyone ever used the BWR throttle body? It's going on my D15B Vtec.

More likely to be a wiring issue. Start with the sensor ground, go through everything.

Throttle sensors rarely fail, and when the sensor actually does, it is usually met with symptoms like: "It falls on its face at part throttle, but if I press harder, it goes just fine."

The vast majority of TPS wear is just off-idle, and part cruise, this is where you should expect problems. Wiring problems can cause TPS problems at any point, and it is best to check there first. If your power and ground are good, use a multi-meter and test the signal wire for abrupt changes in resistance as you go from closed to WOT with the engine off, key on. Reference the specifications for the sensor.
