View Full Version : mercury cougar engine trouble

I've got a 1994 Mercury Cougar that has ran great until today....its 4.6 V8 with an auto tranny....everytime i go over a big bump when i'm on the gas the tranny upshifts and the check engine light flickers on. Also,the engine skips and sometimes dies if i slam my door too hard even when its in park or when i slam the hood down. I checked the fuses and i see no problem there.
any ideas?

Hi sasquatchf-250,

Sounds like you have a loose connection somewhere - start hunting! Concentrate first on the large connectors at the firewall. Also check the connectors at the PCM. This could be a tough one, so be patient.
