2016 5.7 tundra

I’m intermittently losing acceleration and cruise control will not turn on while driving. Any ideas?

 

If it was the old days, it would be a vacuum leak, but I have no idea if the same system is used in our truck.

 

I’ll be driving steady foot on pedal and RPM ‘s just start downward but I will let up off the gas and feather the pedal and truck will resume speed

 

Fuel pump goin out?

 

I had similar problems with a Toyota with a bad throttle position sensor. Does it only happen in warm weather?

 

Not a weather condition I live in San Diego the weather is mostly 70’s

 

Do you have good high throttle response, but choppy/none on the low throttle?

 

Doesn’t matter where throttle position is intermittently lose of power

 

Rather than play 20 questions... sounds like you need a brand new truck. Good luck!

 

This is my first idea too.

 

This happened to my brother's 2014 Tundra. It was caused by the aftermarket LED brake light bulb shorting. How we notice was the taillight would flicker. Removed and replaced the bulb and issue went away. If you have any aftermarket LED bulb that may be the culprit.

 

I do have I taillight issue I haven’t addressed. But I have OEM taillight’s. So you are saying that the taillights have to do with my truck running properly OMG!
Thank you for your input

 

Yup, we were puzzled ourselves, but that solved the issued. We first thought it was the TPS, MAF or a vacuum leak. We have OEM taillights too but added the LED bulbs.

 

Well guess I’m replacing some bulbs today. Thanks again friend
