    Vortec 5.7 stumbles and backfires without giving and check engine codes

    I know it's been a little bit but thought I would give an update. It was the cheaper distributor cap crossfiring. Thing only had 5k miles on it. Learned my lesson. Thanks everyone who gave advice! Didn't realize I had 2 accounts on here. Sorry for any confusion. I am the original poster.

    Cylinders 1 and 2 missfiring

    Ok so I've got it figured out. And I misspoke. 1 and 8 were misfiring. 96 and 97 vs 98+ the number 1 and 8 injector wire pin locations are different at the computer pins. The manufacturer of my wiring harness was awesome and sent me file for both so I could look for diffenances. Thanks

    Cylinders 1 and 2 missfiring

    So what happened, this is all in an 87 s10. I bought a stand alone harness from Howell efi for a 96 half ton. Motor is out of a 98 3/4 ton. Computer has been tuned, but my tuner said he needed a 98+ computer to work with his hp tuner. So I found a 99 computer. Everything works except 1 and 2...

    Cylinders 1 and 2 missfiring

    I did notice that. The 5th plug is for knock sensor. Everything else is running fine. Just not getting fuel to 1 and 2 cylinders.

    Cylinders 1 and 2 missfiring

    So now it looks like those 2 cylinders aren't getting fuel. Would there be any wiring issues for the injectors with putting a 99 computer into a 96 wiring harness? If not then I guess next step is to pull the spider injection.

    Cylinders 1 and 2 missfiring

    I have a motor out of a 96 chevy 3/4 ton. 5.7 vortec. Everything is stock except I put in a 99 Tahoe computer. Cylinders 1 and 2 are missfiring. Have spark, fuel pressure is fine, and holds after turning key off. All plug wires are in correct locations. All other cylinders seem to be doing what...

    4l80e to 4l60e vortec 5.7 in s10

    So looking around, there is alot of info to repin the harness if you are swapping from a 4l60e to a 4l80e. But what if your computer used to run a 4l80e and your harness is set up for a 4l60e? Is it possible that I just need to repin a few wires at the computer? You said one shift solenoid is...

    4l80e to 4l60e vortec 5.7 in s10

    I did have it tuned. But he says he doesnt see anything to make any difference from 4l80 to 4l60

    4l80e to 4l60e vortec 5.7 in s10

    I put a vortec 5.7 and its computer out of a 96 chevy 3/4 ton 4x4 into my s10. Motor and computer used to be connected to a 4l80e. I swapped in a 4l60e out of a 96 chevy 1/2 ton 2wd. Wiring harness is from Howell EFI for my application. Reflashed the computer and no codes or errors. Motor runs...

    Will this work and if so what parts do i need? (1996 vortec to 2006 gto 4l65e)

    So i should probably just get a junk yard 4l60 from this year truck and move the pins in the plug?

    Will this work and if so what parts do i need? (1996 vortec to 2006 gto 4l65e)

    What plug would the 96 3/4 ton have for the trans wiring? Would it be the all electric that the 2006 GTO trans would accept?

    Will this work and if so what parts do i need? (1996 vortec to 2006 gto 4l65e)

    I have a motor out of a 1996 Chevy 2500 4x4 and want to bolt on a leftover 2006 4l65e out of a GTO. I'm trying to figure out what bellhousing to use, and if I will need a different flywheel than what the truck currently has. Truck was connected to a 4l80. Also will the TC from the GTO be fine...
