    Hi Friends, I'm brand new to this forum and to doing any significant maintenance myself.

    MAF sensor troubles.

    Okay, so I'm on my 3rd MAF sensor, and the problem still isn't resolved. When I'm driving down the road, it seems to run just fine. Getting started from a stop it feels quite hesitant, and it bogs down a little too. But if I give it more gas, it picks up and goes just fine. The problem is when...

    A Cleaning Plot Twist

    So the other day I was bored and I decided to clean out my air filter box (still stock with a spectre filter). Naturally, the previous owner of the car never did a thing to it so it was filthy. About 4mm of pure oil and grit all along the bottom of it. After cleaning that, I cleaned the sensor...

    Hi, I've been posting questions regarding the same problem, and I'm not sure if I should start a new thread each time or not? Can someone please advise? The definite common denominator for my problem from all you guys is a vacuum leak. Obviously I have been unable to find it! I had P0300...
