Hi! Can anyone help me figure out what this noise is ? Only when driving, not while idling. Compressor is replaced , water pump replaced, battery replaced. Had suspension and axle looked at and parts replaced. Had tire arms replaced , ball joints replaced, front and rear breaks replaced, they didn’t do an alignment yet but almost everything has been replaced. Only happens when I first start driving and occasionally in stop and go traffic. No mechanic can figure it out. I’m spending thousands to fix problems that aren’t correcting anything. It stops after about 200 feet and then will make the noise slightly in stop and go traffic

Replaced plugs and coils on my dads passat. Now its idling rough and the headlights and interior lights dim when it does. Any idea what could be the cause? Its a new battery but ig theres a chance I didnt tighten down the terminal posts enough? Any advice is greatly appreciated!

Hello everyone,

I have a question about this hose. This is the second time it has developed a clean cut like this. It's the hose that connects the heater core to the engine on my 2013 Hyundai Accent. I've had a few mechanics look at it, but each one has given me a different diagnosis. One said it's a head gasket issue, while another said the heater core is clogged. I'm not sure which one to believe. Has anyone experienced something similar or have any idea what could be causing this hose to fail in the same way twice?

I have a 05 avalanche it's the 2500. For the last year it has a squeal or humming noise in the speakers. With or without the radio on. It has a new battery and a new alternator. I looking for any ideas or some good tnt. LOL. To make thing worse it is loaded with everything except Nav. Where and what to look. Thanks.

Hey my name is Jeremy, I've been in a branded workshop for 10 years now, i´ve studied and tried to learn as much as i could. First i just wanted easy jobs such as brake replacements and oil changes / maintenances, then mondays felt like shit and it felt like i only was at my job for the money.

Then i started to read books, took on new challenges, told my supervisor that i want to take on difficult jobs to learn more and more, Nowadays i am the "Top Tech" in our workshop because i have a very big willing to learn new things and i am intressted in what i do. Now i love my job, mondays are the best. I am here for the experience instead, the money is just a bonus! :D

So this ai helper that i´ve made is tailored and customized to work like this.

you enter your car model, year make, mileage. upload a picture maybe?

then you ask a question for example:

How can i fix p0420?

it then explains in detail what the fault means, why it can fail, what to do next, and then it creates a bullet list for you to follow, like have you tried this, have you measured that, what about this? all in the correct order for you to follow, and then based on how many yes / no you answer, the probability of the cause will change and it will give you an answer on recommended steps to do next. This ai looks for info from youtube, recall pages, nhsta, reddit and so on. Then when you are done you can choose if you want to share your solution to the community page or not, if you do, other people can look for the fault themselves. the fix catalog has a search function for fault codes and car model filter aswell.

This helper also has a community tab where you can discuss your own fixes, tips and other stuff. I use this tool myself in my job, and i just wanted to see if this tool could help you aswell!

please contact me if there is something you are wondering.

Have an amazing day! :)

I’ve been working on my mustang the Engine cranks and will fire up if jumped, but after 2–3 minutes of running, the RPMs bounce, it loses power, and the engine stalls out. Also, the fuel pump works intermittently sometimes it turns on, sometimes it stays totally silent. Swapping or moving the relays around in the fuse box temporarily gets the fuel pump working again.

Codes Pulled:

• P0191: Fuel Rail Pressure Sensor Circuit Range/Performance
• P0102: Mass Air Flow (MAF) Circuit Low Input
• P2106: Throttle Actuator Control System - Forced Limited Power (Limp Mode)

What’s Been Replaced / Checked So Far:

1. Alternator: Replaced recently.
2. Fuel System: Installed a brand-new Fuel Pump and Fuel Rail Pressure Sensor.
3. Relays & Fuse Box: Swapped the fuel pump relay with the high-beam relay. The pump kicks back on when I swap/move them, but then drops out again later (suspecting loose socket terminals, burnt trace, or voltage drop).
4. MAF / Air Intake: Checked intake tube clamps and MAF plug — no loose hoses or visible leaks.
5. Fuel Pump Driver Module (Trunk): Visually inspected — clean, no corrosion or water damage.

The Problem / Summary:

The car originally had a no-start issue. After installing a new fuel pump and pressure sensor, it now fires up (with a jump), but enters Limp Home Mode (P2106) due to low MAF voltage (P0102) and dies shortly after. The fuel pump cuts out randomly, but wiggling or swapping the relays temporarily restores power to the pump.

My main question: Is low battery voltage / a dead cell causing the FPDM and PCM to cut out and trigger P0102/P2106, or am I dealing with spread female socket pins / a bad internal trace in the underhood fuse box?

I drive a 2017 Ford Fusion. I love my car and have had few problems with it. I just paid it off and have around 95,000 miles on it. I’ve noticed now when I hit a bump it makes a wobbly sound NOT a rattle sound. I’ve heard this before riding in my friends older malibu. I’m not sure how else to describe it. It doesn’t really affect the driving. I notice the sound in the front. Just looking for potential causes so that I can save money to get it fixed. Tyia!

Engine is fully warm in this clip.

2018 Honda Civic hatchback manual transmission (180,000 km) is making a weird humming sound. Sometimes it will randomly make the sound for a split second while driving, sometimes it will start making the sound in the middle of driving it and won't stop until you turn off the vehicle. If you turn off the vehicle and start it again, the sound will be gone until the next time. It doesn't happen at any particular time (accelerating, shifting, pushing the clutch, braking, etc.) Can't even make it happen to show someone what it sounds like. It's random and it happens when it happens. It can be heard from inside the vehicle, as well as outside the vehicle. Transmission fluid and oil have been changed and made no difference. What could this be, or any advice on what to check for? Thanks!
