Why when i start my 1996 mercury cougar xr7 it idles down and shut off?


Could be a faulty idle air control valve, or dirty throttle body.
The computer uses the valve to control idle speed.

You will need to have the Ford dealer run an active engine running test with a scan tool to see what fault shows up.

Radiator hose is swelled up


A radiator hose that swelled up is caused by the hose breaking down, we call this a "soft hose" and it must be replaced ASAP. As far as the high idle goes this is caused either by an engine vacuum leak or a defective automatic idle speed control valve. You need to have the dealer run some basic testing with a tool called a scanner to see what is going on.

My 97 Cougar idles at about 1500 RPM at a stop and will accelerate to 40mph without applying the accelerator? Seems to bea problem at higher speeds too. What could be causing this?


Could be a faulty IAC (Idle Air Control) motor. Get this checked out because it will wear out your brakes quick, not to mention fuel mileage, Good luck, Gary

Mercury xr7 starts then starts coughing and chocking like not


My cougar does the same, it starts and then about 1 minute later (or so) the check engine light comes on and the car idles really high, with black smoke out the exhaust. It stays in second gear i think and it will not shift out of it. Max speed is 40 mph with the rpms screaming, it will go off after a long time but this is agrivating. I have a 94 mercury cougar xr7 3.8 ltr Any help please?

1996 mercury cougar xr7 shifting problems


i would need more info but it sounds like your trans shifter cable is out of adjustment ; you need to carefully with the brake on and the car idling; move your trans shifter cable to all positions to check for forward and reverse.
Make sure car is chalked or raised of the ground ,

Usually with the AC on, the idle will slow down, but your case, maybe you set the idle too fast, try set your idle slow down a little bit see if it is working.
