To rich?

[Timing]

So i started having this issue with my car getting high kr at low rpms. So i went and added some fuel cus i seen the cells in the 19.1 range and also lowered the timing in the cells a couple degrees. Now im having stalling issues and my car is all over the place at cruise so bad it will turn off my cruise control. It kind of feels like my tc but i think it just cus the fueling is to rich at those rmps. Im seeing pretty much perfect at wot 11.6:1. What should i see on average from the 7k range down? Im seeing codes p0131 and p0172 but i dont know if they are from the tune or actually the wires. The upstream is brand new denso. Also fuel pump and maf are new. Idle is really rough and has stalled twice so crank sensor also came to mind but i want som opinions on the tune befor i go that route. Thanks

Sorry forgot to mention codes are upstream low voltage and fueling to rich but both could be bad wire on o2 vac leak ect

or to poor?

Huh?

P0172 is telling me you have the tune set too rich at cruise.

P0172 is telling me you have the tune set too rich at cruise.

So you think i should go leaner at the lower maf cells and lower my timing more instead?

[Iceman6669]

Are you getting cruise kr? Cause usually I run like 14.5-15.3 AFR at cruise with like 45~* timing

Yea ima go for a scan and make a couple adjustments and see where im at

Yup so far so good. Cop and pasted my stock 7000 and under maf table and its back to normal. Running alot better with the new pump too

So when you go to add fuel never change the whole MAF table, just anywhere above 7000hz.

MAF tune the lower hz for getting it more spot on.
