This is only after engine is warm.
Even worse in Hot/Warm weather.
It is as if the signal is not being sent to tell it that it is a warm engine.
I have cleaned the Massive Air Flow Sensor.
Otherwise it runs fine.

my tail lights and dash lights dont work i have replaced the fuses and that didnt work.
