03 Frontier no power issue - Infamous Nissan

BlackPlott · 03-05-2021, 09:55 PM

A friend of mine has an 03 Frontier 3.3 Supercharged that falls on its face every time he tries to give it gas. He just changed the TPS to see if it would help and it made it run worse. The supercharger doesn’t even kick in now. This truck used to fly up and down the road. Any ideas? It’s not throwing any codes.

It sounds like a vacuum leak.

Did he post a video of his truck running yesterday? Someone with a SC posted. The bearings sounded like they had come loose and the supercharger lobes were dragging on the inside.

That wasn’t him. I just got in the truck with him a little while ago and seen all the issues firsthand. Thank you for the quick reply.

It could also be a clogged fuel filter. It is located between the frame, just Cab Side of the gas tank with a cover over it so it doesn't get hit by rocks. It's a pain to replace.

He has one to replace it. He changed it last summer, but gonna change it anyway to see if it helps.

The truck seems right as rain on flat ground if you’re going at a steady rate. Once you hit an incline it struggles mightily to climb. Got up to 60 several times and went down to 35 while pulling the mountain.

On the subject of filters, how's the air filter looking?

I'd also check to make sure that the timing is actually advancing with higher rpm.
