I have 5 codes that I'm throwing and they are P0102, P0134, P0141, P0801, & P0803. What are they?

My engine sensor fuse is blown? How did that happen? Also, what will the effects be from this?

Yep, I'd guess ENG SEN fuse too - the MAF, 02's, skip shift and reverse lockout are all on the same circuit. If you have LTs look for a burnt/melted 02 harness.

Well I had to drive about 40 mins to an exhaust shop on open headers so do you think that could've messed up my O2's? Also, I checked all my fuses with a multimeter and ALL my fuses are working fine.
