1999 Toyota Camry Sign In

Hey, guys thanks for reading, and to point.

I have a 1999 Toyota Camry and it randomly breaks down when driving. This didn't occur until a mechanic that's a friend did work on my flexpipe. Immediately after fixing my flexpipe, I started having this problem consistently. My car will break down at least once every 500 miles when I'm driving at speeds of 0 mph (braked at a stoplight) up to 70+ mph (on the highway). It occurs randomly sometimes twice after driving twenty miles. Sometimes once in 2000 miles. Again, my car never broke down like this until after the work on my flexpipe. Basically, a couple of minutes before my car starts breaking down, my RPM will start bouncing and the steering wheel will begin to shake. After driving anywhere from 0 more miles to 1 more mile, my car will start shaking like crazy and break down. If I try to cut the car back on, it will just shake but a whole lot more (than before it cut off on me) and then breakdown anywhere from 0 more miles to 50 more feet.

Here's the weird thing,

After my car breaks down, if I leave it alone for 20-30 minutes, the car will eventually start back up again. Once it starts up, the car acts as if it it brand new and never had any of those problems. The car will be fine and drive perfectly with no problems until another 500 miles give or take 450 miles. My car breaking down is completely F**king random?...

I took it to a mechanic and he thought that it might have been my idle control. And so he replaced it with a used one. After that, my car still has the same problem, HOWEVER, when it breaks down, it shakes only 1/4th the amount as before. It still breaks down at the same frequency and randomness, but the car just shakes a whole lot less when breaking down. Sorry for the detailed post. I'm a novice when it comes to cars, so any advice is appreciated. Again, thanks!

Any trouble codes stored? If so, write down the numbers. This one might be a little complex. Someone is going to have to read data stream information and possibly use a lab scope to monitor ignition and fuel injection operation when the problem is occurring. They also will probably have to monitor fuel pressure to see if it drops out during the stalling episode. The one thing that you or anyone should do is a good thorough visual inspection of everything including O2 sensors harnesses and the area that the exhaust work was performed. Pay attention to detail.

Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.
