Check on SECS monitor the following...
1) The MAP readings are near zero (+/-0.5 psi) when the engine isnt running.
2) Check the coolant temperature reads 80-95 C when fully warmed up.
3) Check the throttle readings are 0 to 100% for the full travel of the pedal.
4) Check the battery voltage is above 12.7 volts when the engine is idling.
And a few questions ....
Does the car rev above 4000 rpm when warmed up ?
Does the car when it cuts out, cut out completely then recover or does it
surge (jerky feeling) ?
