There's a bit of a storyline here and I'm not the most knowledgeable on cars, so bear with me please-

About a month ago I started noticing that when my 99 honda accord EX V6 (83,000 miles) shifted gears around 30 mph the whole vehicle would jerk. I took it in to be looked at down at my favorite place All Tune & Lube because they have ALWAYS been fair and exceptional at fixing every problem. They couldn't figure it out, and sent me home.

Few weeks later my car starts having a bit of trouble starting up. It would shudder and stall right when I would turn the key, and even if I applied the gas it didn't help. About 3 or 4 times I called for someone to come help, but of course as soon as they touched my car it would work. I took it in and they checked my battery level, the wiring connections, and other general things and nothing was wrong.

About 2 weeks ago I'm sitting in a drive through in idle and notice the RPM dropping and the car shuddering for a few seconds every couple of minutes. I immediately took it in the next day.
They took a look and discovered that the distributor box was severely cracked and oil was very slowly leaking in. This was replaced, and while they were at it I had them replace my timing belt since it was about that time anyway. I noticed the jerking at 30mph was not happening as often, and the jerk was not nearly as violent as before (still happens occasionally though). Also, no more shuddering and dropping RPM while in idle.
