This sounds like you have a vacuum leak, or the throttle bore needs to be serviced, here are three guides to help with additional information below.
Use this guide when the engine is cold only:
If your car exhibits sluggish starting in the morning and lacks acceleration initially, but improves after warming up, there are a few potential causes to consider:
Fuel Delivery Issues: It's possible that the fuel system is not delivering an adequate amount of fuel during cold starts. This could be due to a clogged fuel filter, a malfunctioning fuel pump, or a problem with the fuel pressure regulator. A mechanic can inspect the fuel system and address any issues.
Air Intake Problems: A clogged air filter or a malfunctioning Mass Air Flow (MAF) sensor can disrupt the air-fuel mixture and affect engine performance during cold starts. Cleaning or replacing the air filter and ensuring the MAF sensor is functioning properly may resolve the issue.
Engine Coolant Temperature Sensor: If the engine coolant temperature sensor is faulty, it may not accurately relay temperature information to the engine control unit (ECU). As a result, the ECU may not provide the optimal fuel-air mixture during cold starts. Replacing the temperature sensor can help resolve this problem.
Ignition System Faults: Worn spark plugs or a malfunctioning ignition coil can contribute to starting difficulties and poor acceleration. Inspecting and replacing any faulty ignition components should be considered.
Throttle Position Sensor (TPS): A faulty TPS may not provide accurate throttle position information to the ECU, leading to sluggish acceleration. Replacing the TPS can often rectify this issue.
