humidity causes truck to run like crap

[Soapy00]

I've noticed that when it's humid the rpms dropping between gear shifts are random. For instance, i'll roll in to first and it'll grip before it catches unless I go up to 1000rpm to roll in to first. The next shift could drop super fast go to in to second which causes a bang, shift to third will drop slow and cause it to bang by catching up the rpm to the shift. Am I explaining this right? It only happens in hot weather. When it's no humidity and 70 degrees out, it drives perfect. TPS issue?

Try a throttle position sensor. Mine was same way. Did it after rain too.

So after you replaced the tps it was fine in humidity?

Yeh. Hasn't been a problem since. $26 well spent.

Side note. It's always 70% humidity or above where I am seems like so it was a near constant problem tillies I swapped tps.

 

[Soapy00]

is it just the standard tps for a 2005 dodge ram like this?

Dorman Throttle Position Sensor - Save on TPS!

It's srt specific but any local parts store has it. Also disconnect battery for computer to reset.

Is this an easy job? I was going to run out and pick up the TPS to replace mine. Anyone have any instructions on what to do to replace it?

It is dead simple.....only two screws and a connector. Go to 1:37 of this video....it is the same for a stock TB.

Disconnect and touch the terminals together.
