With the volt meter hooked up, sweep it from 0 to WOT slowly and watch the voltmeter. It should be a smooth linear transition to 4.5 to 5V.

Re: I think my tps is bad ?

I just fixed it
I did a 5 psi boost leak test and it had I big leak at the intake tube to tb I just adjusted that and fixed it
And when I had the intake tube off the new aftermarket rebuilt mass I bought locally a year ago the front screen came off and was crooked in front of the sensor and the rear screen was intact and the rear screen trim was loose also dangling in the pipe
So I just took both screens out
And the tb 230 k has a major leak in the o ring seal on the driver side and a minor leak on the passenger side
So I need to get a bbk 58mm tb anyways
But for now the throttle tipping in was fixed
