Your Cougar is equipped with a speed governor, which limits the top end to 115mph. This is due to the factory tires being 'H' rated, so the top speed had to be limited to that rating.

Hello Greg, It's only a guess, but I think you might have a misfire on one or more cylinders causing your shaking problem. If your check engine light is on you may want to run a code scan.

Starts then dies


I think a vacuum leak, or blocked idle air control valve (IAC). Check the large corrugated hose from the air cleaner for splits first up. Then check out the IAC valve.

Im not happy with a max speed.


Thats the limit with the tire speed ratings. The only way to get around it is from a hacker that can disable the speed limiter in the computer. Your car doesnt have the horsepower to go to 5000 rpm in 5th gear.

'94 320i


Hello.

That doesn't sound right, I'd suggest getting the spoeedo checked. Even if you had the close ratio gear box which I think was fitted to the 4 cylinder engines, your speedo should be showing 160 km/h at 5000rpm in 5th.
