Hey guys. I'm getting the above codes 151,157,131,137. Do you guys know if I put long tubes with new 02 sensors and delete the rear 02's if these codes will pretty much be taken care of? Thanks

I guess I will find out, ordered my tsp headers

Those are voltage issues. Changing to long tubes isn't the answer.
Find out what's wrong, B4 you add lt's into the mix.

My car is already in the air with my trans out changing the pilot bearing and i have a broken pass manifold stud so long tubes will be in the mix unfortuneatly.

Any ideas how I should go about solving this issue? My rear o2s will be gone after long tubes.

U should retune to remove the rear O2 codes. While doing that, data log, and see if there's something showing up.
Have you gone over the wiring, connectors, etc?

I dont have own a programable tuner or anything like that. I can check the wiring for continuity and resistance, i havent dont that yet. If the wiring is fine and i install new o2s, what else do you think can cause thia code?

I also have the gm manual for my car, i will look up the procedure for this issue. Thank you for help Old G

After reading, the problem will be either wiring, an intake leak or exhaust leak. I will check the wiring for opens or short, clean the maf sensor and check the vacuum hoses for damage. Hopefully the problem goes away, and leaks with the exhaust should be taken care of with the new components. Carb cleaner spray fine to use to check for intake leaks? If anyone has any other advice or tips, I would really appreciate it.

Yep I found and fixed an intake leak with the old carb cleaner technique.

Those low voltage codes would have me looking for a bad ground somewhere.
