Cobalt SS injectors

[3400-95-Modified]

Well I'm running a stock 3400 only .030 over, and its running around 19ms PW to get a 902 O2 reading at around 4473 rpm, and thats with the Fuel trims locked in at 0%, aka 128 BLM for the OBD1 guys... (I think) And thats comanding a 12.2 A/F... Not sure if that was before or after I tweaked my PE settings down... I think its after because before it would command a 10.8 and be in the 22 to 24 PW on the injectors.

Should I jump to 24#? Remember this is all on my stock 3400... I have a ported Hybrid with a stage 1 cam going in shortly...

i thought that the L67 injectors had a diff clip for the inj harness than the multecs on the 00+ 3400 did

Are the multi tech 1 and 2 injectors the same size?

they do yu have to buy adapters. jon posted a link before or get the harness off a series 3 3800 and splice them on.

Length yes, diameter no and plug type, obviously no...

I have Multi tech 2 in my car which was originally equipped with 1's

i have heard that the l67 injectors use the older style clip like from the 99 GA, but if you are running a newer 3400 then u have to splice on the other cam sensor harness from the newer 3400 harness. you could just use the 4.2L inline 6 injectors, they are same style as 00 and newer 3400 with a flow rate of 28# and maybe more with an AFPR

just to bring this back from the dead.


i had a look at some cobalt ss injectors on the web tonight and it appeared they are the "shorty" version of the multec 2 injectors. same family as the ls1 injectors.
