Hi Scotty, coming to you all the from Australia, i bought 1995 Toyota celica sx with the 2.2L 5sfe engine, it drives like a dream. recently i had an issue with idling, in cold starts it idles around 1200rpm and when i put the car in reverse or in drive it idles below 800rpm with my foot on the brake and shakes like it about to stall when i start rolling in reverse, but when you're drive at speed the is no issues, no loss in power and the rpms don't jump when cruising. i used carb cleaner and cleaned the throttle body and sprayed some when the car was running and it got better for while. do you know what it could be?.            

Thanks.
