Have you checked for codes since you replaced the wires etc?You say its not heating up like it should but maybe the gauge says its not heating up it actually is?Maybe you have a bad coolant temp sensor?

Usually a bad thermostat can cause extra time for the engine to warm up. Check out the thermostat or better yet just replace it.

We need to start with the exact code numbers not code descriptions. We might still have a miss firing cylinder or two.
