Rough idle on VW petrol cars is often due to blocked throttle body butterfly valves. The half moon spaces around the valve allow sufficient air into the fuel injection system for idle unless they are gunked up with oily deposits from the gas recirculation system. As soon as the throttle is pressed the valve opens and the car runs normally. The deposits are easily removed with engine degreasant say every 40k miles.

This is a great video for dummys that dont know much about diy. I like that he explains first the symptoms your car has. He described what your car will do when sensors fail. Thats perfect for someone who is clueless on what to test or where to start to find what could be causing problem and breaks it down to if certain sensors fail this is what your car will do or not do. Thats great that he explained how your car will run if something is bad. That really helped me when it came to trying to figure out what sensor does what, and what sensor will cause your car to perform if its bad. Very helpful and saves me time testing all my sensors. I pretty much can go straight to the one i think is causing my problems. Thanks for doing a video on diagnosing the problems and symptoms of a cars performance so that i can compare my problem to the symptoms he described on video. How your car runs when all is good compared to how it runs if this and this and that is not good? Great video very helpful for blondes/dummies that are self (teaching) in progress!

Mechanic here: Easiest way to diagnose a failing MAF/Mass airflow sensor. 1. Start your car and let it run 2. While car is running, unplug Maf sensor plug and the plug in only. 3. If car still runs after unplugging Maf sensor connector, that means your Mass airflow sensor is bad. If car shuts off then its still good and that is not the problem. Have a good day and God bless!

So i recently installed a cold air intake on my Camaro and my check engine turned on. When i took it to autozone, they said its the MAS. I took it out, cleaned it with the mas spray and tightened up everything again but check engine is still turning on. I did see a difference in the car turning on. Before tightening up everything and cleaning it, when i started the car, it had trouble staying on and i had to give it a little gas to stay on. Now it starts no problem after cleaning and tightening. Do you think i might need a new MAS for my car since i also got a cold air intake? Check engine still says mas is having problems.

I bought a dash board mounted OBD2. It can read out many parameters like throttle body % opening, MAP, MAF, low & high fuel trim, RPM, IAT, O2 reading, battery voltage etc etc. For a 2 litre car engine it's MAF should be reading air flow of around 5g/second at idling RPM with air cond off vs manifold pressure at -7.3psi Setting the car on auto cruise mode and keeping the car's engine at 2000rpm the MAF should be reading around 45g/second when MAP (air manifold pressure) at +7.35psi vs MAF 30g/second at 0psi by MAP. On the dashboard OBD2 show be recorded using a mounted hand phone so that both hands are in the steering wheel. Be safe. Broken vacuum hose or even a slightly loose air clamp can cause atmospheric air to leak into negative pressure side of the manifold and drop MAF reading during idling. Throttle valve body opening will easily drop from 15% open to 13% or less.

I took it to the dealer and he just erased it and the P17FO code didn’t show up on this OBD2 scanner. He asked me to bring it back if there’s issues and im taking it to him tomorrow.

Hi! I’m thinking of getting a preowned full-sized pickup truck as daily work truck. I have a commute of 40 mile one-way (1.5 hrs) then another 1hr drive home in horrid SoCal traffic. I haul mostly network cabling installation equipment in the bed, and do not tow. What brand, model year, engine and grade do you recommend? I would like to have some of the newer active safety features such as the automatic emergency braking system to avoid front collisions, but not as critical as long-term reliability and durability. Any suggestions for a late model pickup truck with Direct and Port Injection. Also, what immediate and affordable engine and transmission mods for reliability and durability do you recommend to protect the powertrain? I’m not looking for more power, just long-term reliability and durability as I don’t have too much money and need a truck for work and personal use. Thank you!

[@8020Media]

The biggest question is what is your budget. Long term durability I'd say avoid GM right now - their AFM/DFM technology is wack. Ford's 5.0 Coyote is a solid motor going to be lower maintenance than their EcoBoost engines. And Ram's Hemi engines are tried and true.

2004 Lincoln LS MAF issues when it’s connected the car will not start completely but once disconnected car runs but idles roughly. Replaced the sensor with brand new one and still does the same thing. Engine code reads the same not sure where to go from here I need help asap !! What would be the next step?

[@breesimmons923]

I believe it’s between 3-4 issues

[@8020Media]

B - What engine codes are you getting?

[@strydyrhellzrydyr1345]

I need help... Mine is doing the start .. and immediately shuts down. Start again.. ahuts down.. sometimes it starts and idles. But you gove it some throttle. It immediately bogs and shuts off. Also.. NO ENGINE LIGHT.. NOTHING

Ok I don't have a code reader and have run into an issue with my 2011 camry. The first start up in the morning is great. The engine cranks right up. After I have driven it for a few miles 10, 20 or 30 and let it sit for a moment it cranks, cranks and cranks then eventually starts up. I recently put in a new battery and replaced the air filter. Any suggestions where to go next? I've been told the fuel pump, but the car idles and runs great other than the start up on a warm engine.

[@8020Media]

Do you have a check engine light on? You can go to any Autozone, Oreillys, Advance Auto Parts, NAPA, etc. and they will read codes for you for free. Could be the starter motor, but yes could also be the fuel pump but I agree you'd probably notice some smaller issues once the pump gets hot and warmed up or on long drives

@@8020Media ok I went to auto one they checked it and found no faults. I’m in doubt what’s next. If it was the starter I would be having the issue on my first initial morning start. Too much gas in carburetor? Check valve? Fuel pump?

F - Only thoughts here are to check the starter motor/solenoid, battery, and alternator. If it's not those, then can dig a little deeper.

I just threw a po172 too rich and po101 maf sensor. Is my problem too rich or is my maf sensor putting out wrong numbers to the computer. At idle I’m getting .9 lbs per minute on my scanner maf reading. What is wrong dude ?

[@8020Media]

S - Your MAF sensor is likely providing incorrect readings, causing the rich condition. Start by cleaning the sensor and inspecting the intake system.

[@streamtards966]

@ Thank you ! I cleared the codes and this is the second day and no more check engine light. I’m sure it could come back. My fuel trims went -15 plus negative. Now they are +5-6 . I cleaned it a while back with crc maf cleaner and took it out again and it looks clean. I put in a new air filter. I will inspect the ducting and air box. Thanks again !

[@dennisbrantley6925]

Other sensors that give the same symptoms other than mass air flow are bad o2 sensor, temp sensor, and idle air control valve. All deal with fuel mixture. Other things to be aware of include, stopped up air and fuel filters and of course plugs, wires, rottery button, and distributor cap.
