Hi,

My name is ***** ***** I would be happy to help. Reminder, I have not been paid at this point and won't be until I receive a positive rating from you. At that point I will receive a portion of what you've already paid Just Answer.

First thing I would like you to do is check the engine oil level. This is more than likely a VTEC malfunction. The most common causes for VTEC problems is low engine oil. Check the engine oil. Pull the dip stick and wipe it clean. Re-insert the dip stick and note where the oil is on the stick. If it is very low or not visible at all on the dip stick then add oil and drive it to see if the problem is corrected. If the oil is full then I recommend replacing the VTEC oil pressure switch. This switch commonly fails and causes this problem that you are experiencing. I will include a link to view the factory part location, part number, and pricing. That should take care of it. If you have any additional questions about this just let me know. Thanks

You can go ahead and rate me positively. Don't worry, there aren't additional charges for posting to this thread after you rate so we can keep chatting. Thanks
