Hey! So I'm having a recent problem with my mustang. The past two days I could feel the power of the engine drastically slow down. And while driving on the freeway I tried pushing it to see what was exactly going on with the engine since no warning lights were coming up. I noticed that the RPM's were only going a little above 3,000 and I could feel the engine shake and jerk (nothing to crazy like it was falling off) it seemed like the engine was "coughing" if anything. But I tried to push it at least up to 4000 RPM's (which isn't usually a problem) and before the car hit 3500 RPM's the warning light of the engine came on and I backed off. Any ideas what is wrong and what I can do to fix this problem?? PLEEEAAAAASE HELP!!!
