that clip is to hold the Injector to fuel rail

That doesn't sound like a GM part number to me! It would only have numbers.

"280150934" is what I have on 12 injectors in front of me from different 93 L67s. I bet the one Pat sent you has that same number. The number is on the gray part of the injector.

Your black ones look like a different shape too :?

yes Pete the one that i sent him and other 2 sets that i have here also has the 280150934 part number,

heres what it does....it wont idle well at all like it will just idle down so low it dies somtimes
but it you give it a little gas its fine....any ideas?
I was thinking maybee an IAC or a bad sensor...the supercharger was taken off and put back on.....this happend since then

is the SES on??, and did you get all the vaccum lines hooked back up??

no light and im pretty certain

Double check the vacuum lines. I left one off when I did my Lower intake Gaskets and had a rough idle and it stalled. If they all seem to be hooked up, then check for any cracks or break points.

well if I unplug the IAC it will idle alot better
it still has a misfire tho

what cyl is the misfire on?? the misfire should be either current with the CE flashing or it will be a stored code......

have you pulled codes, and if so what are they

where can I get somone that has a scanner for it auto zone says they cant?
