so i just removed my stock cat today and put a test pipe, it feels much much better than before, but just a few hours ago, it would idle very low, till the point that my lights get dim...is this expected after the test pipe?...the rpm would drop and go up for a few seconds and would drop again...

i took this picture of the rpm from my phone just about 2 min ago

the car has less back pressure now so that is probably why it is idling low

adjust the screw on the throttle body back to the 750rpm idle

check the code, if your car is obd2 then it should be for the secondary o2 if so then it will not affect the performance of the car

 

hmmm ok cool, yeah its obd2, there are 2 sensors, for some reason the guy in the muffler shop put those on, both of them, but said that it will not effect the performance, hope he's not lying

 

Thats my idle when the car is warm.

The line is 500 rpm. The idle should be at 850 +/- 50 rpm at normal operating temperature.

 

umm sorry guys, where is that little screw to adjust the idle in the tb?...

on the top next to the tps, there may be a plastic cover on it that you have to remove with a razor blade, knife, screwdriver or whatever will work

 

is it right next to the intake piping connected to the IM?, it should be a flat head right?

 

this is a b16...is it the same as a gsr?

&lt;center&gt;

&lt;/center&gt;

 

yep, thats the one

 

for the CEL you need to get o2 bung sensor or some kind of spacers. my friends CEL went on and we went and bought spark plug spacer which can be picked up at autozone and drilled the hole bigger so the o2 sensor can go have a perfect fit and used it as a o2 bung for the o2 sensor after the cat.

hope i didnt confuse you.......if so ill show you pictures of what it looks like. LMK!

 

hey if you take that cover off of the idel adjusment put some monkey snot over it to keep it in place. I had a couple vibrate out and had to make a trip to the dealer

 

check to see if you have any leaks on your exhaust piping.

 

summit automotive also sells simulators that you plug into the secondary 02 sensor plug that will eliminate the CEL

my friend put his cat back on after having a test pipe from a few months and it took about a day and a few drive cycles to clear the cel light on his dash

 

Thank god i have an OBD1, set up.

 

so when the CEL code goes on, there is no performance loss?

right

but the major disadvantage of driving around with your cel on is that another problem may arise that would set off the cel and you would have no clue because it is always on for the secondary o2 and you will be driving around oblivious to that fact that something else is wrong

first clear the ecu, disconnect the battery then turn it on, let it run for 5-8 minutes let it reconfigure and then if its still low, adjust the idle,

if the check engine light is on your going to need one those stimulators for the o2 sensor
