Take it apart, clean the mafs, you see it in the tube it looks like a tiny little wire, buy some mafs cleaner at the auto store. Spray it on there... from a distance, you dont want to break it. then put it all back together make sure there are no leaks.

You need to check the tube from the air filter to the intake. Take it apart, clean the mafs, you see it in the tube it looks like a tiny little wire, buy some mafs cleaner at the auto store. Spray it on there… from a distance, you dont want to break it.
then put it all back together make sure there are no leaks.

After that get youself some soapy water.. lots of soap. at the back of the engine behind the intake you’ll see vacuum line coming out, there is a little elbow that connect two lines at a 90 degree angle. it is made of rubber. Over time this will rot out and crack. with the engine running rubb some soapy water on it, you’ll see if it’s leaking because it will foam up.

it could be somewhere else… but those stupid rubber elbow are usually the culprits.

I’d say check those two things…. one of them is probably your problem.

Look for a weak vaccum hose probably in PCV valve, or a line off as you will normally hear them hiss... if not, it will probably take a pro to find the leak as some leaks are hard to find espcially since that intake makes noise by itself normally. And on your list: Add MAF sensor not correctly calulating load/Altitiude Reading a book I see for common answers…
