Ivereplaced the mass air sensor oxygen sensor intake temp sensor camshaft position sensor and the battery as well as the alternator and I still cannot figure out the problem it still keeps happening please help me I'm pulling out my hair trying to figure this out

The miss is worse when a/c is cut on. It will just jerk until I give it gas and force it to go. The miss is almost always when at complete stop.

It seems to happen when it automatically shifts . Usually on freeway.

He hats the cost for a fuse box located under the hood. I have a fuse in it that keeps blowing

I have checked the fuses, I don't know what this could be. I drove it 9 hours earlier and it was fine. There has never been any kind of problem with it. The only thing I've noticed is the negative post cover is very loose. But do you have any other ideas?

MY BOYFRIEND TOLD ME TRANSMISSIONS NO LONGER HAVE BELTS. WHEN I AM DRIVING THE TRANSMISSION SOUNDS LIKE IT IS SLIPPING SOME BEFORE THE GEARS CATCH. i BELIEVE ITS THE BELTS THAT HAVE WORN . AM I RIGHT OR IS IT SOMETHING ELSE. ALSO THE RPMS DON'T GO OVER 2500. I WAS TOLD I'M OK THERE.

I pulled out this jump wire, I was told this is why my battery won't stay charged even while driving, is this true?

My 2003 Sonata drives fine at high speeds, when I drive below 45 mph, I have to put the accel pedal almost to the floor, and the RPMs go sky high, n its very sluggish. This all started by #1, can only use brights, #2, cruise won't work,#3, heater doesn't work all the time. What is wrong??

I pulled the jumper wire from the shunt that is still in the Trunk Fuse, why would this jumper wire be there ands exactly what is the shunt for?
