Hello, im looking to get something to help me diagnose problems with my cars and help with repairs. I see some on amazon but they are all different but seem the same. The reviews are decent on most of them. Im looking for a bidirectional tool.

I do all the maintenance and repairs on all my family's personal/work vehicles (8+ vehicles new and old) which are all Fords and Chevrolet gas and diesel, and one Hyundai elantra. Im starting to work on other people's cars every now and then and id like to be more time efficient when doing that.

Ive seen autel, topdon and a couple other brands and wondering how these tools work and what the subscription/updates part of it is.

What brand/model would be good for me? Id like to stay under $400 if possible but can wait and save up for something above my budget if it would be considerably better capability/value. (Im in the United States if that makes a difference)

What is the best dewalt 20v ratchet at the moment? I saw one with interchangeable between 1/2" and 3/8", is this the newest/best in 20v? Also is there any deals on it currently? And whats typically the sale prices on these? Thank you.

Bought this truck a month or two ago, had a misfire on cylinder 8, swapped spark plug, coil and wire to other cylinder and the misfire stayed at cyl 8. I ran the engine with no valve cover on passenger side to check the rockers/valves and everything seemed fine. So I pulled the fuel injector for cyl 8 and the orings seemed fine i cleaned it up a bit and put it back, i think i swapped it with cylinder 6 but i forgot. After i did that the misfire went away and the truck ran fine. I put a couple of bottles of fuel injector cleaner in the tank. A week or two afterwards i would get an intermittent code for downstream O2 sensor passanger side.

Truck kept running fine until this week i started the truck and drove about 2 minutes and it started misfiring pretty bad i had to keep my foot on the gas a bit so it wouldnt stall. I got it home and checked codes, it was only one code, cyl 8 misfire. I pulled the passanger fuel rail off and cleaned them up a bit and put them back with new orings and plastic cap. I started the truck and waited for new codes as it was still doing the same thing. I got a misfire code for cylinder 7. I cleared the code and ran it until another code popped up. This time a p0300 mutiple misfire. I checked for a vacuum leak and there wasnt really anything leaking besides the throttle body leaking a very small about near the flap since its a drive by cable it was leaking from there. No leaks anywhere else.

I read fuel pressure and it showed 0psi but maybe it was just user error. I replaced the fuel pump/filter/fuel pressure regulator anyways as the cause wasnt working before. It now runs slightly better, but still stalls and hard starts/barely runs. Fuel pressure is up around 50psi now.

The only other thing I could think to check is the maf sensor or maybe a clogged catalytic converter or bad sensor.

What should I check next since there wasnt a vacuum leak and now the fuel delivery situation should be good. I only have a basic scanner so I can really do any monitoring, I have another truck just like it I can swap the maf sensor from to see if that does anything. I was going to try and unplug/ remove the upstream o2 sensors to see if the cats were causing a restriction but it seems odd that it would happen suddenly if it were that.

Thank you for any advice and please let me know what I could have done differently in my diagnosis also and what you would have done.

Can the 9mm m&p 2.0 holsters fit m&p 2.0.45 and 10mm models? Theres alot more people offering holsters for the 9mm.
