Runs good over 65 below not so well
Whats up yall, I have an 00 alero 3.4 that sputters like crazy under 65mph. To the point where I dont even drive it anymore. Anything below 65 and it cuts off, sputters and just runs horrible. 65 and up is like there isn't anything wrong with it. At first i thought it may be bad gas but that didnt fix it, then I fuel fuel pump or fuel filter. But the fuel pump works and i changed the fuel filter. Also this only happens after the car warms up good. So i can drive a few miles with no problems. With the way gas prices are I want to get the alero running right and let my expo sit for awhile.
Any ideas?

Somewhere in the plugs, wires, coil packs would be my guess.

I would change out the IAT sensor. If it is not reading temperature properly it could cause you to go pig rich and bog like that. Or an 02 sensor since you say it only happens once the car warms up. Leads me to believe that it is working in open loop. Thats a guess for me though.

I havent had a chance to change anything yet but to super white alero, No misfire, no ses lights and it accelerates fine untill the car warms up. Once the car warms up anything below 65 is sputtering and cutting off.
