Bad TPS?

[sfcarlock]

Hello everyone,

I drive a 2006 5-speed Aveo. For a while I was having intermittent problems where I had no pickup, which seemed like it mostly happened when it rained. I was thinking bad TPS, but then it stopped so I never replaced it. Yesterday I cleaned the engine bay and it ran for a while, but had the problem where pickup was very bad again. Today it's starting, but dies after a few seconds and feels like it has a misfire. The battery light also comes on, but voltage is fine and it tries to start every time. I checked the ignition coil and it's good and I cleaned up the spark plugs. Is it likely the TPS? The battery light threw me off. Just wanted some other opinions before I spend the money and time on it.

EDIT: I also lost one of the little white insulator things in the ignition coil plugs, but I find it hard to believe that that could be causing this much of a problem. There is no CEL.

Thanks,
Scott

I checked my compression and got 140, 100, 160, 160. It must've just been coincidence that it started after I cleaned the motor. It looks like someone half ***ed a head gasket replacement before they sold me the car. The head is off. I started a new thread in Engine and Drivetrain.
