I got this car out of storage about a week ago now. The weather has been beautiful for mid March. I've had a few issues with the car that I'm trying to fix. First thing I did was replace the clutch master cylinder and slave cylinder. Clutch works great now. Also, since last fall I've had some issues with the idle. On fast idle the car will start to surge at 1500 rpm and after a good hard pull when the car is hot it idles low, rough, and will stall sometimes. I replaced the coolant temp sensor thinking that was the problem. Didn't fix it, but I did find out that somewhere along the way my radiator caps got switched around. The pressure cap was on the thermostat housing instead of the radiator. Did a compression test just to calm my nerves. Nice even pulses on each rotor face of 75PSI!  I checked the TPS adjustment and found it was out. Tried to adjust it, but couldn't get it to adjust right. I then grabbed a spare TPS I had and put it on. Got it to adjust right (just barely though. It would switch in and out of ajustment) and took the car for a drive. Seemed to work great! Got back to the driveway and the car started running stupid again. Checked the TPS and it was out of adjustment again! I'm going to order a brand new TPS and see if that helps. If not, I'm going to tear the whole top end of the engine apart, replace all gaskets, vacuum lines, and overhaul the throttle body. Also going to do emissions delete while I'm at it.
