    Default 4.3 to 5.7 swap 2003 Blazer

    Hey Guys. I just did a 5.7 swap on my 2003 Blazer and unfortunately my check engine light is. It runs well, but I have codes regarding to the cps/distributor I set the timing many times and made sure it is the 0 - 2 range and code is still present.

    FYI

    I still have the old V6 MAF sensor in.

    Have the 0441 computer flashed to a 02 chevy express van.

    Also have multiple 02 sensor codes saying it is not present.



    Forgive me if this topic was discussed many times, I did briefly look through the 17 pages of this sections and nothing came up to help me out.

    Any help is greatly appreciated!

    Post your tune and DTC's set. Are you using the V-6 distributor with the V-8 cap?
