Low end Sputter
Low end Sputter Hey was seeing if anyone could help having a low end sputtering problems and part throttle. Not sure if it is the tune or sensor problem or what. It runs great at WOT. It is a 5.3 and I just did a cam swap in it. The check engine light came on the other day it was the MAP sensor and TP sensor. Tried to save DTC's but lost the file. I cleared them they have not come back yet. Not sure what to do please help.
The code is related to a vacuum leak. Check everything you had off for the swap, check the MAP seal, PCV hoses etc.
Gearchatter.com has codes, they aren't for the truck 5.3 but OBD II codes are generic. Take a look over there.
