okay lol let me correct my post ...

i had the back fire even before the TH fix so i know they are not hand in hand ..
yes every things hooked back up iv went over it soo many times ... so i know this has nothign to do with it .. i was just pointing out that i had this done ...

okay on top of it all i have new plugs NGK and wires , air filter and have put on a SVT throttle ... and have used intake cleaner to clean.


as well i have a a/f mixture dial in the car and i have it leaned out and it still does it .

car when cold dont like to idle and puffs brownish smoke, the idle just drops off have to play with the gas untill warm ..
and it will stumble then back fire even during driving/shifting .

every thing seems fine IAC,TPS and such

more then likely over looking some thing simple

possibly a temp sensor ? i know some cars use them to adjust a/f mix more so on start up tho

thanks every for the help
