Hi Guys
Getting a really lean mixture.
Symptoms:
RPM Hesitation especially across high RPM
0-100 in 13/14 seconds
Overall sluggish
Checks done:
Removing plugs shows a very white burn (indicating lean)
TPS & Potentiometers (Voltage Looks good on both and Throttlebody coheres with pedal)
Upstream and Downstream Sensors (Upstream fluctuates around 1.46 to 1.78 volts playing with the throttle, downstream doesn't move at 1.46 volts)
Compression Check (14 to 14.5 bar across all cylinders)
Fuel pump (The fuel screen is clear of any dirt) Will get around to doing a pressure check)
Temp sensor (was included in the new thermostat housing, car warms up failry quick and sits just slightly above the middle mark HOWEVER doing a diagnostic check on that range showed 135.7 degrees Celsius at that mark so I'm suspecting it might be the incorrect calibrated sensor)
Suspecting:
Map sensor
Coolant Temp sensor
Fuel Pump
Fuel Pressure Regulator
Notes:
No Codes thrown from ECU
Thank you
