tocinoman25 Posted September 9, 2013 Share Posted September 9, 2013 Was driving to dinner tonight and had to turn back...car seemed to run a bit shaky and then cruise, CEL, and sport mode started flashing. Good thing I was only a block away. Used Cobb AP to read code and it threw a running lean code. What possible problems do i/might i have? I just erased it, reset ECU and reflashed the Map that STi Mikey did for me...I will start her up and see how she runs...mods are...running this map for 6 months now Invidia Catless DP Perrin ELH Invidia Q300 exhaust Stock Injectors Stock Fuel Pump New Spark Plugs (oem NGK replacements) BPd TMIC GFB BPV fully recirculating I checked for any leaks in hoses, fuel tank, all look in tact and nothing out of the norm... I am concerned...shot an email to my tuner...should I datalog? Not sure if i want to drive it...THANKS in advance Follow me on IG @chefodiycarguy and @chefo.soriano Link to comment Share on other sites More sharing options...

tocinoman25 Posted September 9, 2013 Author Share Posted September 9, 2013 Gonna get car up to temp and monitor live data, AF coreection 1 and see if the values hit 15-25 Follow me on IG @chefodiycarguy and @chefo.soriano Link to comment Share on other sites More sharing options...
rob-2 Posted September 9, 2013 Share Posted September 9, 2013 Yup that was the code...where would this hose be located? Most likely turbo side of system under tmic. They might not pop off but still leak. Zip tie them all down. Link to comment Share on other sites More sharing options...

ehsnils Posted September 9, 2013 Share Posted September 9, 2013 Use proper hose clamps and a proper tool for them. Just plan ahead so the screw head ends up in an accessible location when mounting them. http://www.bedug.com/pics/hoseclamp1.jpghttp://www.bedug.com/pics/hoseclamp2.jpg Tool: http://www.bedug.com/pics/hoseclamptool.jpg Don't use ordinary sockets/T-handle since that will put too much force on the seal, and you also risk that the socket sticks to the clamp and you will be standing there with a socket extender while the socket ends up in a tight spot. Spring type clamps are so/so from my point of view. http://www.bedug.com/pics/hoseclamp5.jpg They make things better than no clamp, and works fine when handling vacuum hoses or low pressure hoses, but not for high pressure like coolant. And it can be an effin headache to get the pliers to grip them sometimes and then also move the clamp off the seal area. It's always in a tight spot where the offending clamp shall go. I see zip ties as more than a curse than a solution since it's a problem to get them tight enough where you need them and they are impossible to open when you realize you forgot something that should have been tied down too. Notice that not all hose clamps are good, the wire type cuts through hoses: http://www.bedug.com/pics/hoseclamp3.jpghttp://www.bedug.com/pics/hoseclamp4.jpg At least this is my opinion formed through experience of different levels of headaches with hoses and clamps.
