what exhaust do you have, borla with the block off plate is the only one i know of that has two pipes and can come out of one pipe. i thought you were looking at the spark plugs to tell it was rich on the one side.

 

I will have to look to see what exhausr it is. but the H pipe is a custom one if that matters. looking at the plugs well they where all black. It threw me when i remembered it was tru duals. So why is all the smoke coming out of 1 side of the exhaust? stopped up maybe?

 

true duals dont have a y pipe they have a h pipe. you said y pipe before. post a picture or three of the exhaust

 

As soon as the rain clears up I'll get some pic. But how my exhaust runs, Out of the headers in to a single LARGE pipe. Runs along side of the drive shaft. Then the single pipe goes into a magnaflow muffler then theres a outlet 1 on each side of the muffler for the dual exhaust .

So I guess I should call that a Y. Thanks

 

yep its not true dual, so you are running rich on a cylinders. test your evap system. change your plugs, clean or change your 02 sensors. the problem may be in the tune.

 

Whats evap? lol sry..i have no idea.
wonder y the smoke is coming out of 1 side of the muffler?

 

is the exhuast noise coming out of that side more than the other? it may be that side has more flow. look in the how to and faq sticky at the top of the 4th gen section for how to test evap

 

All that was done away with. i have 2 fuel pumps all steel braided lines come from each pump. 1 pump is strictly for nos use.

 

my plugs foul out sooner or later. once i got the motor done i have not had plugs in long enough to wear out. they foul to the point the motor wont run. change plugs and runs like new. i got one year (10k miles) outa the ngk iridiums goin to try some new bosch once i get time to change rearend and trans.

 

Ok. im gonna replace all the plugs...they look old. Did your car skip or anything? Mine doesnt miss a bit...yet...
