so there you have it.
i had just finished replacing my faulty TPS sensor..the hesitation during driving has become a distant memory..

but....
now my series 4 FC tii is shooting white smoke out from the tail pipe. it's not like a cloud that engulfs my car..but it's enough to be noticeable.

when i'm driving..the smoke disappears (or perhaps it's still there, and i'm not stationary so it can't build up to the point where it's noticeable). occasionally, it does appear from behind me while driving, usually after i let off the throttle a bit then re-apply.

i also have a rough idle now..it jumps between 750-950 and seems to have a mind of it's own. i'm also having slight backfire when i let the car coast in gear.

any suggestions...?
...anybody??

btw, i didn't recalibrate the sensor after installing it...could that be the problem?

any help/suggestions would be appreciated.
thanks.
