Hello, I'm trying to fix a Mach that my friend has.
It only has a few mods, the exhaust, a programmer and a CAI.
The issues it has are the following, the throttle is lagging and sometimes it dies.
The codes that its giving me are
p0433 p1451 p0135 p0155 p1409
I don't really have an answer, but some people won't take time to look up the codes. So I will post them and a few questions that may help get the ball rolling.
P0443 EVAP Canister Purge Control Solenoid or Valve Faulty.
P1451 Lack of Response From Passive Anti-Theft System Module - Engine Disabled.
P0135 Upstream Heated Oxygen Sensor Heater circuit fault - Bank No. 1.
P0155 Upstream Heated Oxygen Sensor Heater circuit fault - Bank No. 2.
P1409 EGR Vacuum Regulator circuit malfunction.
For the mods has there been the EGR delete done? Also is it running with a non-catted mid-pipe?

Yeah I looked for them but non of them made any sense.... Everything seems to be in good shape and I did check the connections and made sure everything was good. No, no cats... EGR is still on
The lack of cats may be whats causing the O2 sensor codes. If you have the programmer, you can turn them off. If not you may have to get mil eliminators.
