Well I've been told by at least 5 or 6 people now to get one of these tests done.
Thing is I know nothing about it I heard it's a test where it checks all sensors and injectors etc etc

Just wondering has anybody had this done so they could tell me what to expect or look for

What kind of readings should I get from certain things?
Nick suspects I may have a bad injector so what pressure or readings should injectors have?
Can anybody tell me what should be the air to fuel mixture??

Hoping to have this done on wednesday before the car gets a paint touch up so I want it all done while the cars gone

Any help Appreciated
Thanks

Idealy you really need the correct equipment to do these tests, im lucky enough to work at toyota so i had the toyota intel tester 1 to plug into my engine to do all the checks which is the tool to do the test that your friends are talking about
then use an exhaust gas analyser to check your air/fuel mixture. I can give you the readings you should be getting but if your doing it manually its quite limited.
For the injectors you can check the resistance with a multimeter, should give something under 12ohms but dont quote me on that, its all in the repair manual anyways.
And same goes for all other sensors checking its resistance to see weather it is stuffed or not.

Hope this helps as i have also been in the same predicament

Car always needs alot of throttle to go or get anywhere the power is jut completely gone it's been this way while
