Ok so I started my car this morning (was in sudbury -10C overnight) ... was running a bit rough... started driving and it was like the on/off choking out of power syndrome... i pulled over, opened the hood and noticed dark smoke out the tailpipe....
I let it warm up more and held the rpms at 2k... all of a sudden the engine jumps to 4k and sounds normal... no more black smoke...
I'm guessing the TPS is gunked with oil and in cold weather it sticks in the open position - therefore running rich. that or it's the AFM somehow.
Ran like a charm all the way back to st kitts.
any other ideas?
