    Hi everyone, I'm a newbie here & would appreciate any suggestions you might have! Thanks in advance for your time.

    My 2004 Grand Prix will start & seems to turn over withno problem, I have a loss of power when at a stoplight or when trying to takeoff to drive. A few times while starting to drive it has stalled on me &fortunately I was leaving a parking lot & not on a main road. It willtry to stall when sitting still for instance at a stoplight or drive throughbut I can usually keep it running by holding on the brake & giving it gas(not good for the car I know). I have no problem when I have it going at higherspeeds say on the interstate, it is only when it is running or driving at lowerrpms. The actual dashboard temperature gauge on my car never seems to berunning hot unless that is faulty too. I took it for a scan & several codescame back...you can see them all below. Any thoughts on where to begin fixingthe issues? Thanks for your help!


    P1106 MAP Sensor Circuit Intermittent High Voltage, P0506Idle Control System, P0300 Random/Multiple Cylinder Misfire Detected, P0135Oxygen O2 Sensor Heater Circuit, P0134 HO2S Circuit Insufficient Activity,P0128 Coolant Thermostat (Coolant Temperature Below Thermostat RegulatingTemperature), P0108 Manifold Absolute Pressure/Barometric Pressure Circuit HighInput, C0245 Wheel Speed Sensor Frequency Error & C0035 Left Front WheelSpeed Sensor

    How mechanically inclined are you?

    I only ask because you could try a few simple things first. I'd try and clean the throttle body and MAF to help with start up stalling first, then I would clear ALL CODES and try and drive it and see what comes back first as thats going to show what the biggest issue is first.

    At a guess and only a guess I'd have to say it's maybe related to a failing MAP sensor because 2-3 codes are pointing directly at that. Also check the wire harness for any damaged.

    I cleaned the MAF sensor, cleaned the throttle body, changed the spark plugs & wires...already running better! Hopefully this was the issue. Next up is working on the abs & wheel sensors. Thanks again for the info!
