Aveo losing power

[aveodad]

Has anyone experienced a momentary loss of power in their vehicle for no apparent reason?

[ontarian_frog]

yes. but the check engine light lit up and the throttle body had froze. what else is it doing? is it constantly? certain rpm? we need more details.

Great thanks,

I'll get details from our daughter, thanx

check to make sure the battery terminals are tight, before you really start to diagnose anything.

Thanx,

No reported engine light, it happens intermittently and rpms around 2k? The dealer could not diagnose.

I know that in my friends, his fuel filter was clogged up a little bit so whenever he was asking for the power it just wouldn't really put it out.

Your car has the hiccups, try to sneak up and scare it.

Honestly it's hard to say. the throttle body could be catching or sticking a little bit?

Mine had a stumble at 2k for a long time... I cleaned the throttle body of some kind of residue and it's run fine ever since.

Could be a bad O2 Sensor, clogged fuel filter, sticky throttle body, maybe even the spark plugs... I'd start by changing the spark plugs, and using a fuel system cleaner into your next fill up of gas, see if that fixes it.

This threads kinda old. Wonder if they ever got the problem fixed. I re red my post and decided to be a little lass vauge...

Someone, from one of these boards reccomended I check this, since I was complaining of the same thing...

Take off the intake hose and using your finger, swab around the opening, being careful not to let it get caught on the throttle plate, it opens inward at the top and is spring loaded. If your finger has a blackish residue on it, clean your throttle plate opening. I used an older can of gumout that read 'safe for catalytic converters'. I also used an old tooth brush to get in there good. When I was done the intake was nice and clean, and the throttle plate opened smoothly and closed fully with no sticky spot.

No more hesitation at 2k.
