when the coolant temp sensor goes bad dose the temp gauge still work? maybe thats my problem.. might as well change it I have changed everything else

 

when the CTS goes bad the engine will be difficult to start and causes all sorts of problems if you get it going

well its been hard to stop ever since my problem started, but my idle is fine just the back fires or misfires and I noticed last night when it dose it my boost goes nutty

 

what exhaust system do you have and are any boxes been taken out, whats the diameter of the pipe?

 

boxes? my system is custom magniflow muffler Moroso mid muffler test pipe and custom downpipe all 2.5" but the system was installed long b4 these problems started..

 

ahhh ( test pipe ) are the O2 sensors still in there they have to be you know

 

yea both o2 sensors are brand new and both work no codes

 

the second O2 sensor pre cat needs to be removed but not disconnected sort of hung up out of the way and not in the system flow, of course you need to blank that hole

 

I have it in place but with an extention and a pin whole so it still gets some Exhaust its reads what should be read if there was a cat there, never had an o2 sensor code, check the readings b4 and after I did the test pipe and they are the same.. the car ran fine for 10k like this..
