[psychoticj]

Ok i grounded both plugs and started the car. Its already to temp. It idle surges still with both plugs grounded. i cant find any leaks any where. i'm wandering if the faiv would cause this or something else thanks.

I would say your ISC is bad causing idle surge covered so many times in the forums. And to adjust the BISS for your ISC position you only need to ground the diagnostic pin. Use the search tool!

Is your isc good? Here is a great link to help you. If you read through this, You should be able to pin point the problem. You have to find the leaks. That doesnt mean you can hear them. Use some soapy water and spray on then if it bubbles you can find the leak.

Do you have a logger or dsmlink. If you did you can see your ISC setting and tps and stuff like that.

the isc is good I had it off already and it moves and the coils spec at 30 ohms. I'm probobly assume its a leak. I'm going to make a blt and check for one that way.
