BreakYaNeckSS Posted February 13, 2008 Report Share Posted February 13, 2008 so ive had this problem in the past but its getting worse now, after having a hard time starting my truck and i finally get it to idle ,it ldles like i have a stage 4 cam in it, ever second it sounds like it wants to stall out and then it catchs itself. but thats only the fisrt part, when i was driving and i would give it gas, as soon as i lett off it would idle waaay down and almost stall so i would lightly give it gass so she wont, but when i was at a light it bogged waay down and stalled. now it does this everytime it idles...im being told it may be the injectors, have a 2.8 pulley which calls for the 60lbs injectors but my tuner said id be aright with the 42lbs, is he wrong, did i max out my 42lbs'rs. any ideas guy will be great, thanx BYN Quote Link to comment Share on other sites More sharing options...
12'SROCK Posted February 13, 2008 Report Share Posted February 13, 2008 even if you did max out your injectors it has nothing to do with your idle, have you done anything different lately? mods/tune? Quote Link to comment Share on other sites More sharing options...

JSTAL Posted February 13, 2008 Report Share Posted February 13, 2008 mine did simular things i checked all my ground wires and replaced the battery and its fine the main problem was the ground strap bolted to the back of the block was lose. I would check that and see what happens Quote Link to comment Share on other sites More sharing options...

.justin. Posted February 18, 2008 Report Share Posted February 18, 2008 P0174 is lean on bank 2. It's possible you have a bad injector or a bad exhaust leak since you've already changed your front O2 sensors. Quote Link to comment Share on other sites More sharing options...
hyperlite Posted March 1, 2008 Report Share Posted March 1, 2008 Check your mass air flow sensor, Mine was dirty and it kept stalling when I let off the throttle. Quote Link to comment Share on other sites More sharing options...
