Question about Toyota Cars & Trucks
Sounds like you have 2 problems, 1) you have a weak battery, 2) fuel starvation i.e choked fuel filter or faulty fuel pump, or both.

Hi all, I had much the same problem, engine bouncing around when idling as if it were firing on a few cylinders and even cutting out completly sometimes. I found out it was the breather hose at the rear right hand side of the engine that runs to the front. there is an elbow piece at the back, this could have developed a leak or in my case it was further back behind the engine, hope this has been of use guys. one thing I would like to point out, beware of the cooling system plastice hose conectors, the outer may look fine but some of mine just brake off and crumble in your fingers, it's as if the inner plastic is destroyed by the hot collant over a period of time, i'm in the process of replacing most of mine.

It could be the TFI (thick film ignition) ignition module on the distributor. When it restarts warm, but dies right away, it has a cranking circuit to initially fire the engine. After that, it switches to run mode, which may be be the problem circuit. Often times, when you take the cover off a bad module, it will have a bubble in the jell where the open circuit has heated up. Heat is the enemy of all electrical components and when they get warm is when the problems show up. This is my first guess. If you have access to a fuel pressure gauge, you can hook it to the pressure tap on the fuel rail and watch for a drop in pressure. It needs around 40 psi to run. Even a clogged fuel filter causing low pressure and flow can shut you down, but it shouldn't run good cold in that case either since fuel demand is higher on cold start. I hope this points you in the right direction. If not, I'd be glad to continue assisting your diagnosis.
