My 06 SC will not boost over 4 psi. Every once in a while it will go into reduced engine power mode. I turn it off for 30 sec and turn it back on and it will run but still not boost. I took it into get the CEL read and it says my TPS and engine load do not agree, There is a problem with the SCIP, MAF, and MAP sensor SO I have replaced ALL of them. I cannot find a vacume leak. Iv changed the air filter and reset the computer. NOTHING works ! after changeing all the sensors I took it to be read again and it says the same problem.I took it to the dealer and the tech looked at it for two sec and said it was my intake. Iv checked it for defects and Iv had the same one for the last year with no problems. Can someone please help?

 

Get rid of it lol that sucks man sorry to here
