How does Roewe 550 step on the accelerator after cleaning it?

You can try the following methods to solve it:

1. Check whether the air filter is clean. If the air filter is too dirty, it will affect the air flow and lead to insufficient combustion. If the air filter needs to be replaced, please clean the air filter base and air inlet pipe before replacement.

2. Check whether the oil circuit is unobstructed. If the oil circuit is blocked or there are impurities in the oil circuit, the oil quantity will be insufficient, which will affect the engine performance. If you need to clean the oil circuit, please go to a regular garage for treatment.

3. Check whether the spark plug is clean. If the spark plug has too much dirt, it will lead to poor ignition and affect the engine performance. If you need to replace the spark plug, please choose a regular auto repair shop to replace it.
