I did a full service on my 2003 ford focus today - oil, filters and plugs.

I did a test run and the car was running lumpy and engine warning light come on! I checked all the spark plugs again and I realised that the rubber gromet from the spark plug socket was on the last spark plug. I took it off and the cars running fine now, BUT the engine warning light is still on. Can anyone help?
 
Check the drain plug is not leaking oil, maybe it wasn't tightened enough or even too much. Also check oil filter is not leaking oil.
 
Mine (04 Focus) came on last week too - apparently the 4th cylinder was misfiring. Plug lead was cracked so they changed that and the spark plugs. Still not right, replaced coil pack, all better.
 
sort it out thanks need radio code now any one help?plz
