Map Sensor
Does anyone out there know if my map sensor can be the sole cause of not being able to accelerate causing the engine to bog and try to die. I have went through most every thing you can check and replaced Ing. mod. cap rotor wires plugs and TPS even found my ESC wire discon. and reattached yet all still the same. I guess Im hoping to here someone with same prob. that had sucess with its replacement. Thanks for any help, George.

Re: Map Sensor
You can check if it functions properly with a DVM without replacing it.
With engine off, ign on it should read about 4.3 to 4.8 Volts depending on your altitude above sea level.
At steady idle, stock engine (factory cam) it should read about 1.5 to 2.0Volts. MAP sensor does not like moisture so it must be mounted with inlet pointing down.
From you description it is more likely that your Fuel Pressure is low.
