1997 Mercury Cougar light and ruff engine start up


You have a vacuum leak. Check PCV hose on passenger rear of engine. Stuck open EGR valve can also be the cause.

My car is overheating. i got an oil change. i flushed the radiator. i changed the fan sensor. help. 96 cougar xr7. oil pressure runs high and then temp. overheats.


You probably have a bad head gasket. As coolant mixes with the oil, it diludes and therefore will cause your oil pressure to run high. Check your oil while warm to see if it looks like choclate milk. Check your tail pipe for white smoke. You can also rent a block tester from Autozone ($25.00 with Autozone's free loan-a-tool program) and buy the test fluid for $8.99. Take off your radiator cap and put the cone in while your engine is running an within operating range. Fill the test fluid to the fill line and squeeze the aspirator for two minutes. If the fluid turns yellow or green, you have combustion/emission gases in your cooling system. This is caused by a bad/leaking head gasket or a cracked/warped block/head. Hope this helps out.

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?

94 Mercury Cougar xr7 3.8l Belt Tensioner Re Install


The tensioner is not adjustable, the spring in it provides a preset tension, I don't understand what you did, but if it came apart then most likely you damaged it, buy a new one, if you get it wrong and it falls apart on the road you are stuck.
