1997 Mustang Cobra no power problem!

GTCOBRAGT · 02-26-2008

I have a 1997 Mustang Cobra and I have a problem.
The car has no power, smells bad, rough idle but no check engine.
And If I press the throttle to the metal, I can hear puffing noise from the front (puff, puff...). I just installed a new spark plugs.

Any advice?

did u gap them right? what kind of plugs?

you probabally mixed up the firing order, did it start before or after the plug change???

Tony, they are Motorcraft and this started before I changed them.
Firing order is OK because I have a scheme.

You may have a coil pack gone bad, make sure all plugs are firing, were the plugs black and wet when you pulled them out, if so you may of got a set of bad motorcraft plugs, Recommend Autolite or NGK.

Thank you for info.

But I notice when I start the engine it works better than after 10 seconds.

could be water in the fuel...happened to me and i spent so much time and money thought my cats were plugged...ripped them off, changed plugs,nothing would work. i put some methyl hydrate and high test in and it fixed it right up.
