long story short...
got code after code.
random misfire
multicylinder misfire
cam position sensor
o2 sensor bank one
o2 sensor bank 2
so im pretty sure i figured it out. all were caused by a very leaky donut gasket.
the springs on my donut were bottomed out so the pipe was still looose.

all i wanna do is get a tune but after driving two hours and waiting 2.5 hours at the shop, to be told the tune cant be performed cuz of all the codes and leaky gaskets, i need to make sure its right.

so i got one more code and am not sure how to correct it but have an idea.
p0037 hso2 bank 1 sensor 2 low heat circuit
i dont know what that means.

if its because i dont have a spark plug anti fowler on my exhaust where the cat should be, would i be able to put a 90 there so my o2 housing is not hitting the bottom of the car? cuz with the fowler i dont have enough clearance.

 

or does the code mean something else???

 

that code is gay and you are correct about the antifouler being the culprit...
Just clear it and tune. That's wut I did... It still pops up from time to time, but I just clear it...

 

well i cleared it and it came back immediatly. like i said i dont wanna get it on the dyno and get sent home again cuz thats like the worst feeling of disgust.

so can i put a 90 on the pipe then screw the anti fowler in???

 

Damn mine only pops up if I idle or drive slow for a while.... U do have the two foulers, correct??

 

i bought two i think... im gonna try to connect the
two. weld something up. the part ill run the o2
parrelell to the exhaust. i gotta remember where i put them first haha then maybe i can finally get my retune

 

Look at the how to on here... U need two put together... And u gotta drill with a 1/2 bit throught the first one... Good luck
