1995 XJ6 VDP 94K Miles

Hi everyone,

I have a weird problem.

As soon as the outside temperature reaches 80°F or more the engine is acting up.

Below that temperature it is a bomb at any speed/RPM's. this engine does not burn asingle drop of oil.

Water/coolant level is good.

Engine starts instantly at any time

But when 80°F (outside) or more, it runs fine at low RPM's but does not want to accelerate properly unless I floor it. It runs like it was not getting enough gas or like it was not running properly on all cylinders (but engine is running on all cyls)

I had a gas leak and had the gas line replaced.

I thought that was my problem but apparently it is not.

I have replaced the water temperature sensor. The thermostat is good as far as I know

The engine temperature is perfect

On short trips I only get 12 MPG

Thanks for your input

Claude
