Today I installed a catless Up & Downpipe on my 02 WRX with NO TUNE. As it is not required for my year's ECU. I DO have intentions of doing so soon...BUT
Everything was fine and dandy after I had installed them today but I started noticing that my temp gauge was riding to about the 3/4 (HOT) mark and then going back immediately to normal.
I figured it was just something to do with my car getting used to the new air flow set-up and resumed driving. Later on in the afternoon after sitting at idle it rose AGAIN and stayed there for about 4 minutes and came back! WTF! And then it just happened again as I pulled into my apartment....I HAVE NEVER HAD ISSUES WITH THIS SINCE I HAVE OWNED THE VEHICLE UNTIL I INSTALLED THESE PARTS.
Does anyone know why these installs triggered this? Or if it is just by some chance some air got into my coolant tank today? Could it just be my car getting used to everything?
It's weird. Any help would be GREATLY APPRECIATED!
