  • How to find wifi hotspot speeds on a phone?

    I use my mobile phone as a wifi hotspot to use internet on my laptop. I currently use a galaxy s7 for this and it's pretty slow. I am thinking of upgrading to an S9 or S10. I am wondering how to find out the wifi hotspot speeds of these phones. My Dell XPS 15 does support Wifi 6, and apparently the S10 has Wifi 6 as well. Does that mean the S10 would be significantly faster as a wifi hotspot? Or does wifi hotspot mainly depend on upload/download speeds of the phone. Thanks

  • Can light scratches be permanently removed from a car?

    Some idiot with a lawnmower slammed a rock into my door the other day, and there is a light scratch in the clearcoat now. I don't think it goes into the base coat because I can't catch my fingernail on it, and if I look at from the right angle, I can't even see the scratch. However in full sunlight, I do see the scratch.

    Have any of you ever had scratches removed from a car before? How did it look afterwards? Are light scratches able to be buffed out completely or will I probably never be able to remove it? Thanks

  • At what point is a scratch too deep to be removed?

    My idiot neighbor slammed a rock into my door with a lawnmower.

    I have a 2020 Hyundai Accent.

    I can get the dent removed with paintless dent removal.

    But there are also 2 small scratches it looks like. They get more visible when it's very sunny outside.

    I tried to see if I can catch my fingernail on them, and I actually CAN feel the scratch with my fingernail. My fingernail doesn't really "catch" on the scratch, but I can definitely feel a rough spot as my finger travels across the scratch.

    Does that automatically mean it's too deep to be removed?i tried to include a picture but  this site wouldn't let me.

  • Did I damage my vehicle?

    Please only answer if you know what you're talking about.

    I have a 2020 Hyundai Accent, 6 speed manual.

    The other day, I was driving about 5 mph, about to park, I pushed the clutch in, THOUGHT i shifted into neutral, and shut the engine off. I was rolling at about 3mph when I let the clutch out, still in 1st gear with the engine off. 

    Again, I let the clutch out in 1st gear, with the engine off, while still rolling foward. 

    The car jerked for a second and abruptly stopped. I started it up a few minutes later and drove away fine, but I'm wondering if I could have damaged my transmission/engine? or if it's probably fine. Thanks

  • No fuel injection pulse on 99 Nissan Maxima?

    This is a question for experienced mechanics, as the Nissan dealership couldn't find the problem either.

    I have a crank/no start condition caused by no ground signal to the fuel injectors.

    I know for a fact that the camshaft position sensor, and both crank sensors work fine.

    The fuel pump is good, all the relays and fuses seem fine, but the ECU is simply not sending a ground signal to pulse the injectors.

    It's not the NATS anti theft system either, because the dealership replaced that and it didn't solve the issue.

    I already tried to send the ECU to a company known as g7computers to have them diagnose it. They couldn't find anything wrong with it and sent it back.

    I have noticed that if I remove the ECU, and put it back in later, sometimes the car will start up and then immediately stall.

    Does anyone know what could be causing this issue?

    Or does anyone know a list of all the sensors that the ECU takes data from the pulse the injectors?

    Thanks

  • What could cause no injector pulse on a 99 Nissan Maxima?

    (I do not have a spare key, sorry thebax2006) Anyway, car is a 1999 5-speed Nissan Maxima... After a 50 mile trip with no issues, I parked the car for 5 minutes but when I tried to start it up again, it only cranks but wont start..... I have checked lots of things so far. -Fuel pressure is good (55psi), -Spark is good (it runs on starter fluid), -The fuel injectors are all getting 12.5 volts of power. But the fuel injectors will NOT fire. The wiring from the fuel injectors to the ECU is good.The wires going from the ECU to the camshaft position/ crankshaft position sensor are good. I checked the resistances of the cam and crank sensors and they are within spec according to my Chilton manual. The fuel injectors will not fire though. I am out of ideas other than a bad ECU... The injectors are clearly Not getting a ground signal from the ECU, but I don't know why.  Car has 250k miles on it. Does  anyone have any ideas for what this could be or what else I should check on it?? Thanks very much.

  • What would cause NO injector pulse on a 99 Nissan Maxima?

I have not tested the crankshaft sensors yet, but I am about to. (I thought that bad crank sensors would stop the car from producing spark, like I said, it has spark.)

  • What could cause NO injector pulse on a 99 Nissan Maxima?

    I have a 5 speed 1999 nissan maxima that cranks but wont start. Fuel pressure is good (55psi), and there is spark, (it runs on starter fluid). But for some reason the injectors wont fire.  It ran fine until yesterday, but now all 6 injectors wont fire. I was wondering if the crank or cam sensors control fuel injection pulse? Or if something else does. Also, the camshaft position sensor on my car is a 2 wire unit. Should this sensor be getting 12v power? When I tested the wire connector with the key on, it had no voltage, but someone else told me that this is normal. Thanks

  • When purchasing a used ECU, do the numbers have to be exact?

        I have a 99 5 speed nissan maxima that is not getting power to the camshaft position sensor connector. I have determined that the wires leading to the connector are both good, but that for some reason the ECU isnt supplying power to the wire. The car ran fine but all of a sudden it cranks and wont start. No injector pulse. No power to the cam sensor harness.

       So, I am looking online for used ECUs, but my current ecu is labeled AJ8-N04 Z84 (as it is a manual transmission), and I cant seem to find any ECUs online with that exact number.

      Am I pretty much screwed? Do the numbers have to match up exactly, for me to be able to swap the ECU?
