Engine dies during idle, after filling up 95-octane gas

[scalawag]

Toyota Liteace 1993.

I only experienced this problem after loading up on 95-octane ProTec gas at Total, testing lang kumbaga. What happened is that the engine dies if I'm not revving it, even during coasting. Pina-drain ko na, then proceeded to load up on regular unleaded fuel. Already tried revving for some time para gumapang yung gas sa fuel lines pero ganun pa rin. Malnis naman daw yung fuel filter nung pinasilip ko. Anything else I need to have checked?

Fuel filter, air filter, spark plug.

Fuel filter, air filter, spark plug.

Fuel filter is clean according to the mechanic. Air filter was replaced just recently, wala pang isang buwan. Spark plugs were replaced only last April. Is it possible that the spark plugs got damaged with the higher-octane fuel?

Fuel lines and maybe fuel contamination. Try to drain all fuel and fill up a 91 octane shell unleaded kahit kunti lang. See what happens.

Already drained the fuel sir. I then replaced it with regular unleaded gas. Tapos nilaro laro ko yung rev for more than 15mins, ganun pa rin po. Almost as soon as the accelerator is released, mamamatay na yung engine.

Have you brought it to a reputable mechanic already? Baka sa Air/Fuel mixture na problem eh.

Check idle solenoid n nakakabit sa carb.yung may wire n nkakabit.Check din for vacuum leaks.

While you're at it, check the fuel pump rin. If carb type ka pa, have the carb checked if it's working properly.

Ganito nangyari sa smallbody ko nuon. Nag try ako ng shell nitro. Ilang beses akong itinirik, nag tulak. May time pa na bypass ang fuel filter, mula binondo hanggang sta. rosa.

Nung malapit na maubos yung gas, balik nako either phoenix o petron. Ok na manakbo, wala ng tirik.

Baka may bumara lang sa carb nyo sir.

Peace out!

Thanks for the inputs mga sir.

Iniwan ko muna overnight yung car. Pag-start ko kaninang umaga nag-idle na sya pero medyo rough. Within 30secs to 1min mamamatay na sya ulet, but it's still an improvement kahapon na bitawan mo lang yung pedal mamamatay na agad. Idle up lang kaya katapat nito? Kasi nung binuksan ko yung AC, umayos yung andar eh.

I'm also inclined to think na baka may natira lang dun sa pina-drain ko na ProTec at maaayos to just by driving around with my newly-filled tank.
