| Post subject: | runs lean on idle |
i took a trip that was about an hours drive .got there and back no prob.when i started the car the next morning it would start up just fine idle good for 2 seconds then just die.........it was lean the whole time on idle.well after some giving it some gas it would hold idle but be lean . i was like F%#k it drove it round the block .ran fine when on boost but off it it would lean out and studder . now i was thinking either something in the fuel line is cloged or my primary injector is on its way out .any other ideas? |

Sounds like the primary to me too. If boost is not lean then you are getting fuel. Could be the FPR too? Maybe its letting too much by at idle? Do you have any way to reading fuel pressure? Do you have the dual stage injectors or are both the same cc's? |
