I need help with my Gs300 it has a 1jz-gte vvti with a 2jz CPU, the problem I have at time I will shut down the car the timer is set for 2min. When I came back and start up it cranks but will not idle unless I hold a rev for a minute or long then it goes back to normal can anyone give me ideas on how to repair this problem. Thanks

 

Is this a 98-05 Gs? I have never seen a 1jz swapped one before.. Hopefully someone else can chime in

 

You might need to reprogram the computer since it's a different computer it doesn't recognizes the components.

 

The GS is a 99
