Draconian Posted October 22, 2015 Share Posted October 22, 2015 2005 LGT 5MT, 122k All stock other than VF46 turbo So a few months back I had an issue with P0302, replaced the sparkplug (was in somewhat bad shape), re-seated the coil pack (which was replaced by PO 20k prior) replaced both + and - battery terminals as they were pretty much shot. Checked for a vac leak, never found one, cleaned the MAF as well. Finally was going to swap injectors and after removing Injector 2 I decided it looked clean and brand new so I put it back in its original place and the problem went away. Now it's about 3 months later and slowly over time the car has been starting to rough idle, slowing getting worse, sudden complete loss of power and then recover about a second later, etc with the the CEL finally coming back this morning on the way to work. Going to try swapping injectors again but any other ideas? Also from OBDII scanner: ETC (F): 192 SHRTFT1% 8.6 LONGFT1% 14.8 MAP (inhg) 9.5 RPM 774 VSS 0 SparkADV 10 degrees IAT (F) 59 MAF (lb/min) 0.466 TP% 14.1 O2B1S2 (v) 0.895 SHRTFTB1S2 % -0.8 All stock other than a VF46 instead of VF40.

xAgyex Posted December 8, 2015 Share Posted December 8, 2015 Max Capacity, dont think I have the orange O-rings. Did you have this issue before? Do you have a link to the O-Ring you are speaking off? Link to comment Share on other sites More sharing options...
Draconian Posted December 9, 2015 Author Share Posted December 9, 2015 Ended up replacing injector in the #2 cylinder. The screen came off upon removal from the fuel rail and the larger o-ring had a nasty gash in it that I hadn't seen the last time I yanked the injector. Have put around 400-450 miles on the car since then and so far it's been running great and no CEL issues. Link to comment Share on other sites More sharing options...
