Car stalled while pressing the gas pedal! need advice! – page 2 – taurus car club of america ford taurus forum gas law questions and answers


For places I can reach, I don’t mind taking them apart, cleaning, and putting back together, but I don’t know what the names of these parts are. What’s the difference between the IAC, EGR, PCV, MAF, etc.? Please pardon my ignorance but it’s just not something I’ve been taught. I can see what the acronyms stand for, but I just don’t know what they look like. Things like valve cover, solenoid, accordion, and so forth I can recognize. So is there a good photo or description somewhere that will help? A search of these terms on the forum turns up hundreds of hits. I’m sure I can search for videos and other help online, but I’m just wondering if someone knows of anything handy? When I read all the tips and tricks regarding cleaning, it’s difficult for me to picture this in my head when I don’t really know what part is being referred to.

I’ve posted the definition of what each part does below. I have a good idea of what it does and how it works but I wouldn’t car myself a pro. If I had known that I would have gained more power and responsiveness, I would have cleaned the IAC and EGR long ago. I always just replace the PCV valve when I do a tune up since it’s cheap but I would stick with Motorcraft brand. Also, I just clean the MAF with CRC MAF spray to clean it. That’s all I do for the MAF and it’s a fairly expensive part. The best way to look at your part is use Google Image search. I would type in something like 2000 Ford Taurus DOHC Idle Air Control IAC and it will show you what the part looks like. If one doesn’t come up for your specific car, you’ll get a good idea of what it looks like and where it is. There are some good videos on YouTube for these types of auto repairs. I would say be cautious because it may not be the right way to do something. It’s always best to read through the comments and watch more videos to become informed. If you can’t find what you’re looking for or unsure about something, I come here to search and read. If I can’t find anything similar to the issue I’m having or unsure, I will post here. There are some sharp people here who know cars inside and out that can point you in the right direction. Someone here can always tell you where something is or what it looks like. I always try to post images, experiences, and outcomes to hopefully help others. I do have pics of the cleaned AIC but I don’t have the camera at the moment. I will upload them later. And I do have all the shop manuals for my car which helps greatly. No pictures but some descent diagrams and good procedures. I would recommend having this always on hand before tearing apart. It will give you all the specifications when putting it back together. Places like AlldataDIY will do a 1, 2, 3, and 5 year subscription to the online manuals. I use this for another car that I have. I got a 5 year subscription for half off by using a promo code I found online. They have been invaluable resource for me plus I’ve learned a lot since they will provide a description of the part(s) and what it does in the manual. Hope this helps.

In internal combustion engines, exhaust gas recirculation ( EGR) is a nitrogen oxide ( NOx) emissions reduction technique used in petrol/gasoline and diesel engines. EGR works by recirculating a portion of an engine’s exhaust gas back to the engine cylinders.

The computer in your car then measures electrical resistance through the MAF as the air flowing through the sensor cools its components down. With a firm understanding of how much air is flowing into your engine, the computer can then direct fuel injectors to add more or less gasoline to the air/fuel mixture.
