Hi, My name is*****'m happy to help you. During our conversation, I may be presenting you with different things to try, and ask you some Questions to get a better understand of the issue so I can answer your question properly. So stick with me to the end, and I am sure we should be able to get this issue resolved for you!

It is fairly common for MAF sensors not to throw codes. Most of the time they don't meter air properly, but still meter air. That is why they don't set codes.

Do you have access to a scanner to monitor fuel trim readings?

Expert:  Jay replied 1 year ago.

Short Term Fuel Trim Readings ( STFT ) should be around 0.. Plus or Minus 8

It was the dash brake light not the I guess I didn't understand him any way it was just low on brake fluid
Expert:  Jay replied 1 year ago.

That is a big difference than getting a popping from the intake and engine loosing power!

Glad it was a simple fix for you.

Thanks Jay!
