Sluggish when cold.
2000 Focus ZTS 2.0 DOHC
Fresh tune-up (wires and plugs), air filter, fuel filter, coil pack, MAF cleaned with MAF cleaner. No vacuum leaks that I can find. But until it warms up its very slow. Just lacks power. No codes registered yet. So what could possibly cause this? Bad temp sensor? Or another sensor? Any help is appreciated. Thanks!
