Hi i have a civic 92-95 hb h22 turbo with aem water meth the runs perfect then I started to feel the vtec is not working and chek the ecu and q31 is fried then i change the ecu and do same thing fried q31 ,the car not bring the evap purge selenoid, my question is how can i do eliminate the evap purge selenoid? just disconect from the ecu?
No cel on just no vtec, then i put the q31 transistor work perfect but a fw seconds and burn again just quickened hard and burn please help

yeah i can cut the transistor but the vtec no quickened why?

 

Vtec has nothing to do with the transistor.

If your intake air temperature sensor is fried, it will throw everything off.
The ecu will not throw a code if your intake air temp sensor is damaged.

 

ok so let me check the sensor !!! thank's

 

Make sure a red/green 2 wire gray plug is running to the intake air temp sensor...

 

dude, i change the sensor and problem still there no kick vtec, all wiring its fine i check it

 

You can't just change the sensor and plug it into the same connector.
Did you make sure you plugged it into the correct engine harness plug this time?

Is your check engine light on?
Have you checked your codes?

 

dude no check engine , no codes .. and wiring is perfect all time works perfect but some day q31 fried and no kick vtec
