Difficulty starting a warm engine

1. Clogged air filter (see «Air filter - filter element replacement»).

2. Faulty power system (see «Checking the technical condition of the power system»).

3. Insufficiently tightened or oxidized terminals on the terminals of the battery, poor contact in the connection between the battery and «weight» (see «Battery - Service»).

4. Defective coolant temperature sensor of the engine management system (see «Coolant temperature sensor - removal, inspection and installation»).
