[QUOTE="Norton, post: 16281141, member: 145307"] I've read about several similar malfunctions, which I don't think cause any kind of check engine light. It will run fine until/unless you get into boost, when you'll quickly heat soak. Cause is malfunctioning I/C pump, which could be due to its fuse blowing, the pump failing, or its wiring harness shorting out. Ways to verify include confirming IAT2, looking for circulation in the I/C reservoir (there isn't much observable in these cars, so I find it easiest to pinch the bottom hose a little, which causes turbulence in the reservior) and/or using a jumper to power the pump when the engine isn't running.
