Hello Respected kilmer , I have a toyota corolla (100k miles) .It starts fine in morning and with one hour of idle .but otherwise takes 7,8 sec to start .deeply stuck since months how to diagnose it.Tried multiples mechanic all in vain.

try having the maf sensor cleaned, and also have the fuel injectors pressure cleaned as in this video https://www.youtube.com/watch?v=bKGI9N_yWd0

sorry to bother u again ,done with both things still no progress.(changed complete fuel filter and pump also but in vain)

  • Injectors and sensor were taken out and cleaned with a spray cleaner .Is this also workable?
