Hey guys i just installed a new cat, also have a scanner and at idle the long term fuel trim is at 12-14 and short is around 5 really high correct? as soon as i rev it the long term comes down to 2-4% and stays while running and as soon as i let go off the gas its back to 19% Lt......vacuum leak?
the problem i see is that my O2 reads rich here is what i got
LT FTRM1(%) : 13.3
O2S11(V) : .810
O2S12(V) : .785
so i understand the cat is not doing much maybe is topped off as far as it can clean if i had a vacuum leak my O2 would read lean wouldn't it?
PS thats what the scanner reads im assuming it means O2 bank 1 sensor 1, and O2 sensor bank1 sensor 2?
its a 2.3 L
Really need help asap i don't want to blow my new cat
