Engine taking a long time to warm up?

2-wire ECT sensor have the correct resistance?

Exhaust leak near or upstream of the O2 sensor?

Fuel pressure too high?

Valve clearances set to spec?

Fuel injector stuck open?

Did you use an OEM fuel pump or aftermarket? Why exactly do you think it's running rich?
