Newby here...but trying to learn...
I have a 2nd Generation '94 4Runner that I have been having a few problems with. After I drove it to Texas from Oregon, It started making a really loud sound in engine compartment, almost like a muffler was blown or something was bad. My uncle suggested changing air filters, so I put a K&N filter in, but no luck. The weird thing is if the engine is revved above, say, 2k, the loud sound goes away, but comes back when idling.. Any Ideas? (Dr. Z? I've read some of your posts, and they are very informative.) After about 7 minutes of driving, the loud sound goes away, until the next start
:mad:Secondly, now my Check Engine light comes on at random times, and then goes away randomly. Anywhere from 200 miles to 5 miles. Checked the codes and got 14 and 25. I ran a fuel injector cleaner through, but to no avail. I don't have a ton of money, so I'm trying to fix it on my own if possible...
Any and all suggestions are more than welcome!
