Idle speed @ 1600rpm
EA MPI S pack 5 speed
Before taking my car to the Ford dealer for work unrelated to the subject problem, I washed down the top, spark plug side and injector side of engine with pressure washer. Engine started okay and I drove home.
Next morning car started okay and ran as normal and I left for 40K trip to dealer.
Car gave a jolt on power being applied at a roundabout and I thought "condensation in distributor". Balance of trip at highway speed uneventful.
Told dealer I thoiught I had moisture in distributer and could they clean it.
Dealer replaced distributer cap ("worn out" ) and all the leads ("terminals corroded").
Picked up car from dealer and when I drove car into shed at home I noticed idle was 1100rpm. I thought it may fix itself in the next day or so, as the dealer had disconnected battery.
Next morning start up idle was okay at 500rpm or so, however when hot it was back at 1100 Later it then (whilst being driven) would cut out (stall) whenever clutch was depressed. Got home and let idle at its 1100rpm idle speed which it did for a few minutes then a short hunt and it would cut out as though the ignition was turned off.
Took car back to dealer however it was no longer cutting out but idle speed still 1100rpm. Dealer removed throttle body and fiddled around for an hour and a half " Said they ('EA's") were very difficult to adjust but hoped it was fixed.
Now it idles at 1000rpm when cold and 1600rpm when hot!!!
Any clues on whats wrong . The dealer (Edwards Ford Koo wee rup) obviously does not have much idea.
Did my egine washdown wet something else best not "wetted"?
Thanks for any suggestions I have a Gerorys but I find it a bit brief for my level of expertise.
