eratic idle and stalls out?

i dumped the codes and i got 10 11 15. i know 15 is because i have a chip in it. i checked codes without the chip and got 10 11. and i forgot to mention that all my sensors are new. all of them but one which is the act one i believe. new o2 iac egr maf map pcv tps ect.. and i put in a whole new wiring harness that inspected and cleaned every connector bedore installing it. all new ignition stuff too. (i replaced everything on the car because i restored it and wanted it like new). also checked for vacuum leaks. checked relays and grounds. and the volt gauge surges along with the rpms( i donk know if that normal). checked fuel pressure. it was a bit off but now smells more like fuel from the exhaust. and runs hotter?? any ideas. ima at a stand still. and yes i ran the whole check list. :/
