My car runs very lean on idle and it's running hot. The car won't start until it's completely cooled down. I was wondering what causes this problem.

I adjusted the size in the EMU parameters from 280 stock to 550cc, but I think it might be the EGR removal that causes this problem. I blocked the EGR because my manifold doesn't have a EGR port (HKS). So I think the ECU thinks the airtemp is higher than ik actual is. So the mixture gets leaner than it is supposed to be.

I hope it can be compensated by the EMU. Anyone?

Whatever your injectorsize is, try to get
the compensation fitting to 14.7 AFR on idle.

it sounds like you may have removed it incorrectly, or have a leak at a blockoff plate, or possibly still have the EGR valve hooked up and have a constant vacuum source going to it.

Could you outline your EGR removal? If the EGR was removed or bypassed correctly you shouldnt experience any differences in how the motor runs. I removed mine a week ago and it runs absoloutly normal except for the CEL
