hi, thanks again for your response. im working today so cant really do much, but i went out and started the car, it did smoke quite a bit on start up and for about a minute. disconnected the map sensor plug and although i didnt drive it it does seem to rev with less hesitation. plugged it back in and its like its got a misfire or holding back at around 1500--2000 revs. and i can hear the turbo whine/whistle through the exhaust?. so it does point to map fault and wastegate fault??.. you wouldnt happen to have a spare map sensor for me to try would you?. dont want to wast money trying stuff that may or may not work. you know how it is on a budget and all that. im in Dalton by the way. cheers.
