Also, i like having a clean rag to cover up the throttle body once you remove the air intake hose, just to be sure that nothing falls down into those holes while you have it exposed. You'll need a set of screwdrivers, a can of MAF (mass air flow) cleaner and a can of TB (throttle body) cleaner if you are feeling more ambitious. The piece it connects to is called your throttle body, when you depress your gas pedal, the throttle body opens, allowing air into the engine making you go faster.ĭont be too intimidated about this, it is actually a very easy thing to to yourself.

Directly connected to that is your MAF housing, and connected to that is a long wide tube (air intake tube, we'll call it for now) which goes from the right of the engine (while looking at it from the headlights.aka the drivers side) to the rear-center. First, find your air filter, and the box it lives in is called your air filter housing. There are a few things you'll need to identify to do this, but no worries, it is easy.
Just for the fact that you are looking for the answer yourself is proof that you have more technical skill or at least the drive to develop it than most males. But, with all of the general tune up stuff i did, i cant be sure that the one single fix was the final fix.Ĭlick to expand.don't apologize. I actually think the MAF sensor was the problem, when the car needed more air to handle higher rpm's, it struggled.

When this happened to me, I did a general tune up, remove and replace fuel filter, change plugs and wires, change oil and filter, sprayed out the MAF sensor, let it dry, reinstalled, start it back up to make sure everything was installed correctly (actually was.but there was still a misfire, turns out one of the plug wires was faulty), and once I was sure, i filled up the tank, ran a fuel system cleaner through it for a full tank (a drive from st louis to chicago), filled the tank again and drove it back, no problems since. I'm no pro, but if it starts and idles fine, your air flow is correct for low rpm's and your fuel injectors are at least getting a trickle into the engine.
