Replaced TPS

I've been having the same problem. But it didnt start until after the ported TB, so I just thought it was that, and normal. I only pulled 367 at the dyno. The TPS CAN"T be robbing me of that power. Right?? :confused: Have to break out the boroscope.

Bro if that's all you dyno'd you have some serious issues! No dyno will read that low in any weather unless something was seriously wrong!

Yes, a bad t.p.s. can rob power.
If it (for example) is only showing 70% throttle opening at wide open throttle, the timing and fuel tables will be incorrect and power will be lower than normal.
And, it won't trip any codes...

Same thing here also, after TB install thats when the problems started. I am going to get mine tomorrow and install this weekend and see if I notice any difference.
 
Ok I replaced my TBS as well, Must agree idle hang at red lights are now gone :)

And does feel little more crisp when nailing the gas.

Thanks for the info On this it helped alot.

i know this an old thread but i just stumbled acros it and i have the thing with the indle hang at a red light o sometimes when i rev it up while not moving it takes a minute to come down. it always seemed to me like this was some sort of computer issue. is there any way to tell if the TPS has gone bad or should i just go out and replace it. If i should just go out and repalce it where is it located and how diffucult is it to change out?
 
It was cheap enough just to replace it. $20 I believe.
2 screws and a wire harness. Took a couple minutes.
If you look at your throttle body, it is the black sensor on it on the drivers side.
 
That could be. I don't have a truck to look at anymore.
I was just going by memory.
 
Well your old ass memory sucks!:D
It is on the passenger side and it is the smaller, flatter sensor above the Idle Air Controller valve. Upon install, you will need to insert new sensor, then rotate to align holes. The potentiometer is spring loaded and will have to be engaged before lining up holes for the 2 screws.
 
How would one go about pulling the connector off of the current sensor for removal??
 
Just use your thumb and pry up the plastic tang, and unplug. Really easy, but may be stuck as it may have never been replaced.:D
