VHslow Posted March 16, 2010 Report Share Posted March 16, 2010 (edited) Are the TBSS injectors bigger than the LQ9 injectors, I did my intake and TB swap awhile back but used my stock injectors because I didnt feel like swapping connectors on my harness. I keep getting a code for system too lean both banks. Also does anyone happen to know the gm part # for the connectors I will need to install the TBSS injectors Edited March 16, 2010 by VHslow (see edit history) Quote Link to comment Share on other sites More sharing options...

Also does anyone happen to know the gm part # for the connectors I will need to install the TBSS injectors what year was the intake off of? mine were bigger i think stock ss inj are 28 or something and the tbss ones are 36 or something sorry i'm not dead on i didn't pay attention when i did it, but they are bigger. i just spliced the wires with the new pigtails if you need pigatils i'll swap you i need the pigtails you have now.

detjoe Posted March 17, 2010 Report Share Posted March 17, 2010 hard to say its out of fuel with out a wideband or looking at your logs but I would guess that it is a code associated with removing your cats. Just a guess. Quote Link to comment Share on other sites More sharing options...
chpspecial Posted March 18, 2010 Report Share Posted March 18, 2010 lq9 injectors = 24 lb/hr tbss injectors = 29 lb/hr This sounds like and intake leak problem more than an injector issue Quote Link to comment Share on other sites More sharing options...
zippy Posted March 22, 2010 Report Share Posted March 22, 2010 If you didn't change the pcm for the injector size you wouldn't have wanted to change them anyway. Quote Link to comment Share on other sites More sharing options...
