Why is my Vauxhall Combo Life not accelerating properly?

I recently purchased a Vauxhall Combo Life and I have noticed that it is not accelerating as smoothly as it should be. I have checked the spark plugs and they seem to be fine. What could be the issue?

It sounds like you may have an issue with your fuel injectors. They could be clogged or not functioning properly. I suggest taking your vehicle to a trusted mechanic to have them checked and possibly replaced.

Another possibility could be a problem with your transmission. It may need to be flushed and have the transmission fluid replaced. This could improve your acceleration issues.

It could also be an issue with your engine's air filter. If it is clogged or dirty, it can restrict airflow and affect your vehicle's performance. Try replacing the air filter and see if that helps.
