just not right!

Hey, hope someone can give me some info. I have a 90 teg GS, I have new wires, plugs, cap, distributor, pretty new fuel filter, used fuel pump, so recently, it has been running fine in the morning when it is cold, but as soon as it warms up it boggs down at low rpm, and doesn’t seem to have a whole lot of power on the highway. I still will get 120-140 km/h out of it, but sometimes it is spuddering. Kind of at a loss with what to do?? Anything I could try?

:rant:

check your connections on the plug wires for one thing… make sure everything’s tight.

Does it seem like a fuel problem or an ignition problem?

O2 sensor, the 90-91 have this problem a lot. Mine did for the first 6 mo I had the car, I replaced everything I could and nothing got rid of it but the O2 sensor.
