driving to get lunch today and while in first gear babying it along i hit reduced engine power.. pull into the parking spot and order food... go out ten minutes later back to normal. when i got back to work i scan the codes two were found p1183.. which said unknown code with research i find its supercharger inlet pressure or something like that. second it p0068 which the scan tool says absolute pressure/maf/mass airflow/ throttle position correlation. guy at work said his wife's cobalt (2.2) did the same thing dealer said it was throttle body and replaced it under warranty. he said the part would have been 1100. i erased the codes and drove around probably about 10-20 miles and it hasn't come back. freak accident or will it be back soon? and what is it i researched but found many many different opinions. please help mods in sig

hmm any one.. well as an update i drove the car more and it runs better than before.. but its alot cooler and less humidity right now as well.

 

i know climate has alot to do with it... say it was really cool at night and u were giving it hell...the next day its hot and u give it hell the baro...and sc inlet pressure have to recalibrate and it keeps a record of like 3 hard pulls....i forget the rest i had this issue and im in auto tech so i used our ondemand ande mitchell and it told me alot about it..ill try to look it back up..but ive had this problem a few times now.. it seems as if alot of people are running into this...i use my interceptor gauge to erase the codes..

 

a datalog will tell you whats wrong and weather its a electrical or mechanical issue, i believe the inlet pressure is read by the MAP sensor ontop of the blower

 

yeah thats what i was thinking here in Missouri the climate changes alot i mean alot.. one day its no humidity and then two hours later humid as hell. when i went to lunch it had just started raining slighty the steam coming of the roads and humidity jump to about 200% lol
