I have an 03 focus se sohc, car starts slow with a sporadic misfire whenn engine is warm, after its cranked it runs and drives without misfire. Ive replaced plugs, wires, coil pack, ckp sensor, still no fix. No vacuum leaks either, any suggestions??
in the end the last few weeks of it living, if i hosed off the engine tell the temp gage went down it would keep living...
the last run was a 2+ hour drive non stop on the first 65F day of the year
and i did'ent have a hose with water to cool it off...thus on start up it blew sky high in 10 sec
using water is not a fix, it just puts off the end story temporarily.
