OK my 2001 Chevy Silverado 1500 I just changed my throttle position sensor my fuel regulator sensor and fuel filter and cleaned mass air flow sensor and the truck is still sluggish

Any codes?

It threw a bank 2 o2 sensor but I don't have one on my truck

Bank 2 sensor 1 or sensor 2? Also did you just take it out?

Just now and says bank 2

If you can get the actual code "p04??" I can work with that a little better.

Yeah it just threw that one service engine light came on I replaced the other one an hour ago but now the p0420 came on

It just threw the po420 code bank one I'm at a dead end with this truck aren't i

What do I do about that p0420 code its throwing

P0420 is typically a bad catalytic converter. Maybe it's clogged?

I took them both out and just put pipe in there place but all 02 sensors still in but it still is running sluggish it bugs down and u have to almost floor it to get it to down shift

That's got me a little stumped. Either the tips isn't reading right or the valve body is having issues. I would suggest checking fuel pressure too.

What should the pressure be and when u say tips what is that exactly

Sorry I meant tps. Auto correct messed that up.

What is that I know everything about old trucks and diesel but this gas and new shit lol not so much
