ish lots of codes after blowing off an intercooler pipe

**SykoraA4** · 08-09-2008 09:56 AM

hey guys,
a few days ago i blew off the pipe from my turbo outlet to the intercooler, and didnt have the ability to fix it where i was at the time( about 2 miles from my house) i was able to limp home (barely, and probably not a good call at all...) but i didnt have a choice. I got home, fixed her up and the next day got a CEL. i hadnt been going into boost much after that, but i soon realized even if i did, i wouldnt boost more the 7 to 9 psi. (im chipped and should be around 18,19ish, spiking at 21) i dont know if this is because of when i blew apart that pipe, or some damage i might have done driving it home... here are the codes...

Just clear the codes and see if they come back. Nearly all of your codes are because the hose blew off, 02 sensor high resistance and boost deviation.

use this site to look up your codes

yeah had the same problem a couple weeks ago. i cleared the codes and havent had a problem since.

**SykoraA4** · 08-09-2008 12:50 PM

sweet, thats good then. would this explain the boost too? weird thing is though, there were a few times when i got full boost back.

**SykoraA4** · 08-10-2008 07:54 PM

i cleared the codes and the car was back to normal. but then i got the cel again and its doing the same thing. anyone have insight?

**mike-2ptzero** · 08-11-2008 03:03 PM

Did you look to see what codes you have now?

**SykoraA4** · 08-12-2008 05:10 PM

this is what i got now...

17536 - Fuel Trim: Bank 1 (Mult): System too Lean
P1128 - 35-00 - -
16502 - Shareware Version. To Decode all DTCs
P0118 - 35-10 - Please Register/Activate - Intermittent

and its still pulling my boost way back.

I would ask you what your fuel trim readings are on block 032 but you only have the shareware software.

But 16502 is a coolant temp sensor code, so you might need to look at replacing your sensor.

**SykoraA4** · 08-12-2008 08:05 PM

would the coolant sensor effect the boost like its doing? or is that most likely cause of the fuel trims.

**mike-2ptzero** · 08-12-2008 11:18 PM

Most likely all related.

**SykoraA4** · 08-13-2008 07:13 AM

thanks for all the help mike. ill pick up a new sensor.

**SykoraA4** · 08-19-2008 08:14 AM

so the new sensor is in, but it didnt solve the boost problems. im thinking my primary o2 sensor is shot, (p1113) causing me to run lean and go into limp mode? does this sound correct?
