It'd be nice if the computer tells us all the time when any of the parameter sensors and actuators has a problem but this is not the case, also at times it will pop a code/s and there's nothing wrong with the trouble area. On the thermostat removal it will caused the computer to lock the fuel loop control on open loop and giving it fuel at all times due to the coolant temperature sensor unable to provide the computer the correct input signals to control fuel
Okay the TPS is the throttle position sensor and the MAP is the manifold absolute pressure sensors check and test these 2-sensors and tell me what you got.
Please! Explain this and lil bit confused here:
take it back into town, it is back to smooth again. If I drive around town, stop and go, it goes back to hesitating.
Here's my checklist on what could cause hesitation/bogging/jerking problem:
Fuel injectors dirty/sticking.
Mass airflow sensor/Airflow meter.
Throttle position sensor.
Manifold absolute pressure sensor.
Fuel pressure regulator leaking, fuel filter or defective fuel pump.
False air leakage.
Foul/defective spark plugs.
Open spark plug wires.
Ignition coil/Coil packs defective.
Incorrect ignition timing.
Cap and rotor.
Note:If it doesn't apply disregard.
