New here thanks for.any feedback in advance. My 96 es300 has 261k miles on it, runs like a champ. Mechanically could not be better. Check engine light code p0121 came up so I replaced the tps. Car ran fine for 5 minutes then quit. Light came back on, I couldn't get a scanner so I searched around the Web and a suggestion I found was to clean the idle air control valve and sure enough it was clogged. Cleaned it up and ran great and died. It'll run for 5 minutes then quit. Wait a little bit then I can start it then quit. I can't take it anywhere because it will leave me stranded. Am I missing something what else can I check
