When starting car the idle runs rough and then will eventually die. Will die at stop lights. If I press the gas while at a stop I can keep it running by shifting to neutral or going to park.
Err Codes: P0300, P0442
What I have done since(with no resolution):
1. Cleaned Throttle Body
2. Cleaned the Mass Air Intake Sensor(in front of air filter)
3. Replaced Ignition Coil
4. Replaced Spark Plugs
5. Replaced wireset
6. Replaced Ignition Control Module
7. Checked the Fuel line pressure and is registering 58-60psi.
My ideas are
1. The Throttle Position Sensor(TPS) is bad an thus will need to replace the entire throttle body.(Autozone does not have the Throttle Body).
2. Intake Manifold leak/vacuum issue
I am not a mechanic, fast learner, trying to resolve this.
Any help is very appreciated.
