First my truck is a 2006 Chevy silverado 1500 4x4 5.3l v8.

Problem 1:
Slight vibration on gas pedal. The only time I really feel it is from a slow acceleration. NOT while driving thru town or highway speeds. Only taking off from stop signs etc...

Problem 2:
One single popping sound every time I start my truck. Maybe literally 3 seconds after it starts I hear the “pop”. Turned the ac/heater/everything off and it didn’t make the noise. Wondering if I need to replace something or if it’s normal.

Problem 3:
Maybe this isn’t even a problem but I’m throwing it out there anyway.
Sounds and feels like it isles funny. RPM’s look fine and don’t move but it sounds like it’s idling higher then lower and I can feel it when sitting in the truck. Like I said, the RPM’S don’t move when it happens.

Hope i don’t sound “stupid” here. I’m just a girl that loves her truck and wants to keep it running good. I know how to do minor things and willing to do what it takes to take care of my baby. 👍😁

 

How many miles on your pickup? Might be the injectors are getting dirty. I'd put some Techron or Seafoam in the gas tank and see if that helps.

 

there is 149,xxx miles on it. I will try some Techron or seafoam and see if it helps.

As for the popping noise, I found that if the ac is off and heater also off it doesn’t make that popping noise.

Thanks for the advice.

 

Bad mounts on motor and transmission. Motor slides
