    Constant Codes coming back P0104, P0171, P0174

    Yup need to test voltage in park at idle and when in gear at idle. These codes popping up results from low voltage when car sits between traffic lights cause of a failing alternator regulator. Voltage should read the same in park/neutral and when in gear while parked. Regulator should adjust...

    2014 Idle Hunting High Fuel Trim

    I use BlueDriver scan tool. Gives fuel pressure readings. Not sure about forescan. If you do find it. Fuel pressure should read near 40psi at idle and cruising speeds. Will drop in the low 30’s at WOT and spike up when you let off the trottle. Anything out of the ordinary, start looking at your...

    Mustang wont start HELP

    Can you hear the pump kick on when you turn the key to the ON position(engine off). Try cycling the key a few times before cracking the engine. If it starts, you may have an internal leak inside the fuel pump assembling.

    Rear O2 sensors off with stock tune

    Final Update****THE FIX! After much thought and searching of similar issues. I decided to dig a little deeper into the Evap system. Aside from Evap purge valve located under the hood on the driver side, P0443 can also be triggered by the VAPOR CANISTER VENT SOLENOID. This little trouble prick...

    Rear O2 sensors off with stock tune

    Update: unsure of what adjustments were made on stock tune I went ahead and reinstalled the 91 Bren tune and did a drive cycle. Couple concerns I noticed. 1) Evap triggered a pending code, then went ready shortly after. 2) O2’s went ready, then triggers a pending code. Catalyst still not ready...

    Stock tune only reading front O2 sensors?

    I’m curious if anyone who runs stock can only pull data from front 2 sensors and those with a tune are able to pull data from all 4 O2 sensors? When I’m on stock tune the rear O2s says not supported. When I have my tune loaded I’m able to pull live data for all 4 sensors. 1st on this trend...

    Stock tune only reading front O2 sensors?

    Returned to stock and my Blue driver scanner only supports front O2 sensors. Reads all 4 when Brenspeed tune is installed. Is this normal?

    Rear O2 sensors off with stock tune

    Smog testing is right around the corner. Had a CEL recently for Evap. Replaced the Evap cleared the code and all was well. Several months later another CEL. Scanned for codes and all 02 sensors were triggered. 12v to all sensors. Remaining 3 wires to O2’s ohms out to ground, telling me there’s...

    Serious fuel pump problems..HELP

    ohm those 2 wires from FPDM to PCM. You going to have to get creative and run a long enough wire extension from one end of the car to the other so your multimeter leads reach but it’s what you’re going to have to do to make sure you don’t have a break between those two connections. Aside from...

    Check for proper grounding of the FPDM to frame (G400) on the schematic. Also check frame ground from battery. Make those surfaces are bright and shiny. Ohm out the wires/cable of both ground.

    Car idle issues and running lean with no codes

    I just went through this issue myself. Here is the FIX. 1) If you have an SCT scanner go to special functions and reset KAM. Reload your tune, if your car is tuned. Otherwise ignore this step. 2) If you don’t have an SCT scanner. Unplug battery negative cable. Place a jumper wire between...
