Lumina Problem / General Car Problem: Surging Engine
#11
Thanks again guys for all of the input. My dad doesn't really know what might be causing it, but he hasn't had a chance to look at it really.
Dustin- Yes, it does have the 3.1 motor (great motor IMO). I will check for carbon build up, since the car never really goes on long trips or anything, it's more prone to the build up. (Trust me, this happens way too often in my truck)
As for the fuel filter, I just replaced that in the fall....so I'm sure it's not that. FYI, the filter on that luckily is on the bottom of the gas tank...much nicer than our HHRs! As for the pump, not sure... I can hear it working, so that's a good step!
No lights on, no codes...so that's no help for me. I guess the next thing I'll try is accelerating with the brake like you said to see if it's the plugs/wires...

Also, I saw something online about the Torque Converter Clutch (or the solenoid) going bad on these cars. Anyone heard of that? It does seem that this surging happens more at 45ish and above speeds, but it's really hard to tell. Can't really notice it in the city, but at idle it's slight, very slight...

Ooooo....thats kinda new for a filter,,but then bad gas can do strange things...I wasted a new filter by running cheap cleaner in the tank once....tough one...a lot of possibles there, but no codes..hmmm..would look at all fuel possibles as all the electronics are monitored,,they don't monitor liquid..also check your evap can or a lose vac line....

And that's why it makes me mad...
I have run different fuel system cleaners through the car before... Wonder if one of them could have hurt the brand new filter? Doubt it though.... Hopefully I can drive this tank of gas out, and I'll fill it up with some good fresh new gas. See how that does.

Yeah, I'm going to put some premium in from a good brand (probably Shell). Don't know if their gas is any better than Kroger, but who knows... I'm not driving very fuel efficiently either, so I can use it up a little faster... I'm going to hope that's what it is, since like I said the gas is 5-6 weeks old.
