for some reason my camaro has lost power, when your in a higher gear it feels like it has no power at all, especially uphill, when you rev it it feels like it has alot of power, but at some point it feels like it has none at all... this happened after i did headers/exhaust and z06 rims
thanks

Check your timing retard.Do a board search on knock retard and get the resistor and install it. The header's are causing false knock and retarding the timing.

so dont i get a lt4 knock module?

1racerdude

LT4 knock module is a waste of money, it won't fix it.

DiabloGT

so where do i get the stuff for it?

1racerdude

Do a board search for size and installation and ya get the resistor at Radio Shack

i doubt this is the problem... but what does it do when your catalytic converter starts stopping up?

DiabloGT

what do u mean about stopping up?

hallbilly

my brothers 93z had the cat clog up and he lost all power pretty much... would idel and stuff... but he could barely make it up the road to his drive way... so he introduced the cat to a big steel pole and a hammer

Well, let me think here... My car has a nice set of heads/big cam/and LT's with no tune the car never retards the timing and doesn't throw codes. It threw a code once but that was because my Y-Pipe slammed the bottom of my car and then it imediately when away, so yeah I guess the LT4 KM that is in my car IS garbauge and a waste of money.

DiabloGT

oh no then, cause i just bought a new hi flow carsound cat, and i heard the resistors dont do anything when u get them? and to the other people are lt4 kms useless?

'94 Bad A Z28

No they are not useless.

DiabloGT

what if i get a pcm tuned by madz28, will that be able to take out the false knock?

FutureZMan

LT4 Knock isnt a waste of cash, not even close.

DiabloGT

can anyone answer this?
