do any of u guys think a exhaust leak at the y pipe can set a code 43? theres a leak right where the 2 pipes off the manifold come together. the car has no power at a 1/4 pedal or more.

let me know what u think

 

knock sensor

 

when i first got this car a couple years ago, the retards that had the car before me, put washers on the bolts between where the y pipe and the cat connect to make it louder , and it had a code 43. i took out the washers and tightened everything back down and the code went away. now that i blew a hole in the y pipe the code came back. so, u dont think the knock sensor could pick that up as false knocks?

 

o yea it could...i know my y pipe isnt welded by the previous owner and rattles like crazy...and sometimes i get a check engine light flash. Wound up being code 43...now that i think about it..the thing rattles like crazy when im stopped. I think you just solved my problem too haha.

 

how does ur car run? mine runs like **** all the time, but only get a SES light once in a while.

 

runs fine...i just the ses light for like 5 secs then it goes out every now and then when i come to a stop..

sounds like you might have a problem somewhere else

 

my problem prolly is just a faulty knock sensor then

 

most likely, probably just retarding timing like crazy causing the no power and ****ty running conditions
