You can get a free scan from Autozone, Oreilys, or Advance auto parts. This should indicate a problem. If the standard test scanner does not verify a problem, the Dealers have more advanced scanners which can capture intermittent problems.

There are so many possibilities that you need more tests to find the problem. Offhand, if this is a V6 engine, there were problems with intake Manifold runners and sandwich gaskets for 2 piece intake manifolds.

Stuck manifold runners could provide lousy low rpm performance and perfect high rpm performance just like you describe whether a V6 or V8. The 2 piece intakes were used on V6 engines and once you get above midrange in Rpm, it could run acceptably at higher Rpm.

It could be a spark plug, plug wire, or a coil. Sometimes thay break down intermittently. If it needs a tuneup, that would be the first thing to do.

You need to have it scanned to see what code turned on the light. Check your gas cap, make sure it is tight.

What engine do you have?
I have a 2002 Escape with 3.0 V6. It sounds like the ignition is getting damp and the engine is misfiring. If the CEL is flashing, you really shouldn't be driving it. Check the owners manual, but you could damage the engine.
Anyway, go to an Autozone or other parts store. Many will scan your engine for the DTC code for free. This code will give you a clue.
My code was for a for a cylinder misfire. I was close to 100,000 miles, so I replaced the plugs first, then the one coil. It was the coil.

SOURCE: 2004 Ford Freestar SEL sputtering, check engine light flickering.

Engine lamp will come on if idle is too low / fuel mixture is too lean or too rich.
A faulty spark plug will cause this also.

2005 mustang my car started to misfire sputtering while giving gas and when coming to a stop rpm go down to 500 then back to 1000 but only sputters just once yesterday bad maf or fuel injectors


if you have an obd scanner check the codes.....could be as simple as a dirty fuel filter...also shows symptoms of a failing fuel pump (electric, mounted inside tank)....If you dont have access to an obd ll scanner, take it to n Auto Zone, Murrays, Napa, Firestone, or Goodyear, they will usually scan it for free........good luck.

Backfiring when starting, sputtering, light white smoke out tailpipe, fluid out the tailpipe, check engine light is blinking.


When the check engine light is on, the light is telling the driver the computer has found a problem that may affect performance or emissions. You should get the computer scanned for trouble codes.
The smoke and fluid could be coolant or trans fluid being burned thru the cylinders.

Have to push gas pedal to the floor for car to start. its an 89 gt mustang with the 5.0l. after it starts it runs fine, sometimes the engine light comes on when i get on it real hard. but there are no hard...


This would indicate a problem with the automatic choke. Putting the pedal to the floor creates the same effect as the choke when starting the car.

2003 mustang gt will skip when it hits about 1,500 rpm but after that it is fine but you can still feel a little skip in it.

I have a similar symptom. No engine light lite. It can be felt as I accelerate moderately from a standing stop. Then as my engine begins a climb in rpm in seems to hesitate for a brief moment and then continue to increase rpm. Not sure what this is.

Is this the symptom you were identifying?

Only 1000-2000 RPM? Does it do that in any gear?

A couple problems with a 95 mustang


for the top, I would suggest to check the gears of the motor if they are still meshing perfectly with the entire system.  It could be a stuck up motor, to be sure you need to open it up.  For the transmission, you may want to check the fluids if it needs changing and also check on the solenoid if it needs some cleaning.
