I need some help
I have a Jaguar x-type 2.1LT petrol
for two weeks theres been a problem with my car,
when the car is cold for 14 hours and I start, it starts slow.
What I have checked and What I have done and replaced to the car in the last ten months is in the list below:
Brand New battery
The starter is good it has good voltage, alternator is good and voltage is good.
fuel pressure is fine 4.5bar as it should be
vaccum is not leaking and neither is oil leaking from anywhere
spark plugs were changed 6 months ago in perfect gap. Coils are fine, cables are fine.
ps for a few days I have noticed that if before starting the cold car I press on the gas pedal and release it and start up, it starts normal
then I thought it might be the throttle position sensor, I then changed the whole throttle body that I bought on ebay. But the problem is still there
I think there might be a problem in Crankshaft
what do you think it could be? What advice can you give me please
The ECU is not giving me a code, when I attach the laptop to ecu everything is normal.
I have had jaguars for some years and have basic knowledge but some things one can get stuck
my 735-rpm in idle and ignition timing 3-degrees
i have spent too much money and am sick of it
