I have a Mercury Cougar it runs rough but has a good idle only runs kind of rough when driving down the road and second gear it loses power and my running lights do not work I cannot find anything on the internet about the Mercury Cougar I have its a 1993 if you could help that would be awesome thank you I love your videos and it doesn't lose power all the time

well, try tuning it up and cleaning the fuel injectors first, oten just that. Pray it's not the transmission going out..

The transmission is strong shift smoothly and runs great it only does it when shifting into second sometimes not all the time it just loses all power like the like it has no gas and the rpm drops

I will check the fuel injectors
