Idle the engine and check for air leaks by spraying WD-40 on your intake, vacuum lines and injectors. If the engine bogs when you spray, you've got a leak.

Check the engine temperature sensors with a multimeter. Take resistance readings at low, moderate, and high temperatures. Resistance should be higher at low temperatures and lower at high temperatures.
