rough running 1994 ssei
 

I just got a fuel injector from another memer it looks different tho are the 1992-1995 l67 injectors the same as far as flow rates and stuff? I think this might be the cause of the rough running?

Get a scantool. Your car will log misfires. Clean your injectors. All 92-95 L67 injectors are the same. 29lb/hr. Can we see some pics?

Can I ask what promted the injector swap? was it running rough before you replaced the injector?

the Injector that i sent was from a 92-95 L67, and on that i am 100% positive... out of the 2 sets that i have here, they all look the same...... that one came out from the matching sets

pulled everything to change the supercharger coupler and liost an injector somewhere...yah its stupid...any way heres a pic a crappy one but you can see a difference the left one is the one I got all the others are like the one on the right

Do your injectors have a part number on them. I've never seen your year L67 looking like that.

sorry this is for a 94 not my 97

ok what we are saying is that we have Never seen the injectors that are on your car, the one that i sent you was an OEM......we are questioning of yours are aftermarket..... and are looking for a GM part number on them

this car was given to me by a friend I dont know much about it its not in the best condition I can go look for a part number tho
btw what purpose do the metal clips serve on top of the injector?

01d034B is the only thing I can find on the black ones

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?

well found the problem....coil packs all three were bad replaced them now its fine...cept 2 mins later the friggin coolant bypass craked out of the lim :roll:
