Hello, I'm Danny.
Having the check engine light on means there is a diagnostic code or codes stored in your vehicles computer. These codes are what is causing your car to not perform well. The first thing you need to do is have the codes checked. To save your car from being damaged when the computer senses these trouble codes it will put your car into 'limp mode' until the problems are fixed. Here are a few tutorials showing what is involved with retrieving diagnostic codes from your car and low power:
Once you perform this on your car get back to us with the code information and we can then properly diagnose your vehicle and send you tips on how to fix. Hope this helps and thanks for using 2CarPros.
