Question about 2000 Lincoln Navigator
There are several parts which control the idle. One part is called an "ISO" motor and it is suppose to regulate the air flow and fuel mix for the engine. This part is probably dirty or worn. Another part is the TPS throttle position sensor which regulates the fuel and spark timing settings.
Even if the "Check Engine" light is not on, there are sometimes codes stored in the onboard computer. You can get a free scan at Autozone or Oreillys and it may tell you which part is bad. The main problem with diagnosing both of these parts is they are variable and not Off/On type switches. Your problems occur when the variable setting is wrong for the moment and not a complete failure.
The plugs are under the air intake manifold. Disassembly is easier because the water system is now separate from the air intake manifold. There was a problem with sparkplugs breaking into 2 pieces on removal. Plugs are rumored to be good for 100,000 miles per the manufacturer.
