94 GT Problems

I have a 1994 mustang GT 5.0 manual trans. that will sputter when it hot or cold and when we press down on the gas fully then we receive minimal power(slow rise in rpms) until we get to approx. 2000 rpms in which we will not get any more power. However we can still gain speed or get power above if we are lightly touching the gas. The current gear is not the problem. We can be on a 15 degree grade uphill and still be slowing down(not very fast but still slowing down)with the gas at full throttle but with just a little bit of throttle, we will get better response. Basically, on level or uphill grade, with the throttle at full we have extremely little power/response. but with very minimal throttle we get more power/response. Our beliefs is that it is the calytic converter.

Re: 94 GT Problems

For what it's worth- it sounds as if your engine is not getting enough fuel. While you are correct that a plugged CAT can cause problems too, a plugged fuel filter, weak fuel pump, or bad fuel regulator can do the same.

A weak fuel pump or bad pressure regulator is easy to check with a fuel pressure gauge (about $15). And of course, the filter is the lowest cost part replacement if this has not already been done.

Save that expensive CAT replacement till last. I guess you could always drop them to see if it helps.
