My Jaguar 2.0L V6 is losing power under load and when engine or air is hot?

Power loss in your Jaguar 2.0L V6 under load or when hot could be due to several factors, including fuel delivery issues, ignition system problems, or overheating. A clogged fuel filter, failing fuel pump, or dirty injectors might restrict fuel flow, while worn spark plugs or ignition coils can cause misfires. Additionally, overheating can lead to reduced engine efficiency or trigger limp mode. It's advisable to run diagnostic tests and check for trouble codes to pinpoint the exact issue.
