Toyota Solara, 1999, 80,000 miles, V6.
Usually after long drives after 30 min or so as I come to a stop my engine starts to feel like it is being over worked and starts to make a sound as if it is about to die out but it doesn't. The RPMs fluctuate when i come to a speed lower then 5MPH. When i reach my destination I try to figure out what exactly is going on so i turn my car off and open the hood. If I try to start it immediately after being turned off it will crank but wont start. If I let it sit for a few minutes it eventually starts up again. Could it be the alternator? I have no idea. I just changed the battery a few months ago so i dont think it could be that. But it just feels like the car isn't putting out enough power or something. This only happpens after long drives but otherwise its fine. Please help me!

It may be worthwhile to check the codes in the computer, that may give you something to work with.
How old is the fuel filter?

If it was mine I certainly would. Take a look at the plugs as well ( not that that would be your prob).

The codes can be read with a code reader that you can buy, or pay a shop or stop at an autozone and they check them free.

Keep in mind the code is just a starting point, not a magic bullet. There are a list of maintenance items that should be done if you don't know that they were done. We can go through that after the problem is resolved if you like.

Codes can get listed regardless of the check engine light. This is where I always start. Maybe there won't be codes, but if there is you have an angle to work with.

I have this same issue, same 99Solara SLE V6. I'm changing the EGR valve, and have been using supreme gas and changing my oil more often. on top of that, I've had an oil leak which has forced me to almost completely flush the system with new gas over time since I've leaked so much. since this time, the symptom of really hard idling leading to a stall has not happened - the stall also caused the breaks to weaken, and the lights to go dim a little bit as the engine undulated from enough energy flowing into the engine to what seemed like minimal energy flowing into it, causing it to die. when it undulated far too low, it would just stall and die.

i'm wondering if the symptom will happpen anymore. i'm considering a transmission flush as well, and i'm going to use full synthetic oil from now on only. any input?
