ok ive scanned my PCM for hard and soft codes, ive done a bunch of custom tuning to the PCM, ive done a complete tune up using only the parts everyone told me. and im still only getting like 150 miles per tank (mpt) i know this is wrong. even in my trans am with 340 horses i was doing better.
my question is. maybe its my 02 sensor thats acting funny. but im not sure if its the front one on the manifold or the one behind the cat. according to
www.zzperformance.com they say the one behind the cat has nothing to do with the PCM or the with the way the car really runs pretty much its just there to let you know your cat is good or not. so im thinking its the one on the manifold. but everyones telling me to swap out the one behnd the cat
im gonna do the u-bend and resonator delete and just take out the rear 02 anyways. and just add the delete. but can i remove both of them and just put 2 simulators in my car or will that be bad
i figure the simulator would be best because its always giving a perfect reading.
