Start the car today for the first time this winter, I had to floor the gas padel to make it happen. The car first ran fine when stayed around 2k rpm, once the car was warmed up there is burning smell and black smoke comming out of my tail pipe (plus the idle jumps around under 1k rpm). BTW, I am running single turbo with PFC.



I checked the vacumm line that goes into the MAP sensor, it's still connected. Anything else I should look for? If this is cause by my initial flooding, how can I fix that?



The engine feels like it's going to stop anytime, I will be hesitate to drive to the shop like this.



Thanks. OY

black smoke is gas..... i replied on your other thread https://www.nopistons.com/forums/pub...DIR#>/wink.png

I saw it, thanks Jon. When is our gathering?

check the tri7 forum

check the temp reading on your pfc. when my temp sensor was busted the car wouldn't start up when it was cold cause it didn't know to feed more gas in. Also, check the pim reading. When my gm map sensor was malfunctioning it was a very high reading and was highlighted.
