So I recently had a problem come along with my 1994 metro. I was driving down the highway and all of a sudden I started to feel the power of my metro subside and a sputter/ticking noise coming out of the muffler. So I let off the gas and when I pressed back down the metros power returned but only for a few minutes before the noise came back. I replaced the fuel filter and the problem has seemed to subside, but my MPG has been altered I was getting consistent 45-55 mpg now I am at a solid 32-36 tops. Has anyone had this problem ??? Any help would be great. TIA

Sounds a little like the exhaust is stopped up maybe. ^o)

check your catalytic converter. hit it with your hand and see if it is the source of the "sputter/ticking noise" that you heard coming from your exhaust.

when the cat starts to go bad it can build up exhaust pressure and you will lose power. hit a bump and the loose particles in the cat shifts around (your ticking noise?) and relieves the backpressure and your power returns.

Is the check engine light on? If so have you retrieved the fault codes?

Does the light work? I still might try to retrieve codes. Not all fault errors will trip a check engine light.

Well I have kept up with maintenance so the light should have no reason to come on. But I will get the codes checked asap. I believe since mine is a 94 the place where I would check is under the hood

Sounds like a melted cat and it's plugging or restricting exhaust flow.

you lost power, it god noisy......then power returned.....but mpg has dropped.
does your car feel slightly weaker now?

when my geo began burning its first valve i was climbing a steep highway speed hill.....lost power, got noisy, backed off gas waited a second then had power return.

car was a little weaker but mpg dropped a lot!

do a compression check, then do a wet compression check. that will tell you if you started burning a valve.
