Then mother fitted her unit firstly I started noticing the same hard start from no where. Engine turn on while driving. Vehicle ignition switch off while acceleration pedal pushed on an on going motion out of no where power is gonna and vehicle ignite switched off luckily no vehicle was behind me. Then when you try turn ignite nothing happens vehicle will only switch back on and turn on ignite after +- 30 mins. Stuck .But that's not the same feedback i got from guy that was sent Angelo from car track to inspect vehicle. Not even a word of this problem isn't caused by the CAR TRACK UNIT. He also experienced these issues when we went on a test drive before he started working on the Corolla when Angelo the TECHNICIAN spoke to me when i got to work, But guess what my issues are still not solved been sorted in both my vehicle's.
