I have Kenji's ECU and he has told me to unpluge the EVAP purge soleniod because I am having hard start-ups and the gas isnt pumping properly into the car. How do I do this? Is this something easy to do or do I need someone who actually knows what they are doing to do this? I didnt want to ask Kenji because I have already email him so many times and I dont want to bug him. Thanks!

 

It's right behind the intake manifold hanging on the firewall. You just unplug it.

Who just gave the mullet a email.

what is a evap purge solenoids function?

 

Quoted from George Knighton, who I think quoted/summarized this from Kenji-

OBD1 equipped vehicles open the EVAP purge solenoid as soon as the engine is started. This vents the gas fumes into the intake manifold to be burned.

On OBD2 equipped vehicles the EVAP purge solenoid will not purge the gas vapors until a certain RPM and vehicle speed are reached. This allows for more complete combustion of the excess gas fumes.

When you switch to OBD1 on an OBD2 equipped vehicle the OBD2 EVAP purge system still remains in the vehicle (obviously). However the EVAP purge solenoid now opens immediately when the car is started. This causes the vehicle to idle roughly and run rich. Ever notice when the rough idle occurs there is a strong gas smell coming from the exhaust?

The solution to this problem is to either press the accelerator for a few seconds and allow the fumes to clear out, or simply unplug the EVAP purge solenoid. The latter being the more simple and more effective solution.

I have tested this on my own vehicle along with my friend’s vehicles and it fixes the problem.

Now some may be thinking that it is not legal to unplug the EVAP purge solenoid. Well, neither is switching from OBD2 to OBD1 thus negating that argument.

 

To purge the evap can...

I am dealing with this issue now and if I just unplug the evap will the gas not vent from the tank anymore because the 2 way valve won't open? Is this safe?
