are the ends different diameters

I replaced it twice , but I still have the same problem , the check engine light is still on and the car some times do not start or may need a long time to start .

Had our mechanic replace the two throttle sensors and still does it. Having to towed to dealership in Springfield,MO today.

need it A.S.A.P only got a day permit

Problem happened yesterday car has been driving fine the oil and transmission fluid is fine still starts but sound rough

I just got some work done on my car. They fixed strut mounts and AC. When driving home the other day, (I had AC, radio and lights on) the engine cut out between gears. It's not gear specific, it happened between 1st and 2nd, 2nd and 3rd, and 3rd and 4th. Only happens with AC blowing. No idea what it could be... With everything cutting like that it leads me to believe it's something electrical. Had a shop check alternator, putting out 13v (little low, but not worrisome). Any ideas? Here is a video of it happening... (delete spaces between dashes.

So I have brought my car to the shop a few times now. First my car was stalling out when I would idle. My mechanic just put an additive in and said it was fine. Then it completely died on the highway. They replaced the crankshaft. Then my car decided it wasn't going to pick up speed at all and I found out that the catalytic converter was clogged (probably from the additive) so I got that fixed. Now when I drive it takes longer then normal to speed up. My car is an automatic but it's feels like I'm badly driving a manual. It will rev up between 3 and 5 depending on how fast I'm going then after a few minutes will drop down under 2. Any ideas?

I have replace all sensors - cps, cam, and air flow, replaced all hoses, what would cause this. I have had some say it could be the starter or cylinoid - but was also told no - cylinoid would make a click, no clicks, starter it wouldn't turn over, and it does eventually most of the time

Changed rear brakes rotors calipers and lines but still locking up

My car failed emission with a code of P0501. Can anyone tell me what this means and about how much it will cost to fix it.

It says there is a speed sensor problem but when I go to stop at a stop light or stop sign, occasionally my car will shut off completely when I go to push the gas pedal. Sometimes it starts rough and I have to pump the gas (while in park) to get it started and continue pumping gas to keep it running. After it's been running for at least 20 seconds, I can put it in drive and it'll be fine. But it randomly dies and starts rough and when it's just sitting, running in park, the engine will run rough and almost die then kick back up. Paid 400$ for a mass air flow sensor (from an auto shop) which is what Hyundai dealership told me was wrong with my car and that did not fix it. Still does the same things it did before. Need help?!
