hello ladies and gent's I have been trouble shooting for a couple weeks whenver I can find time.. heres what I did.. I removed and inspected the O2 sensor... i seemed fine no carbon build up at all in fact it looked practically new.. removed the fuel pump relay and the car would not stay started.. so I think thats working..removed the OVP relay and the car would not start at all.. removed the EHA valve connector and it ran more rough than usual.. I removed the connector to the IDle control valve and the engine speed does not increase..I switched the wires around.. again nothing changed..well it would not stay started more than 3 secs I should say.. I removed the Idle control valve and visual inspected.. it was filty I barely discern the internal components but it does vibrate when current is applied.. so I not sure if its stuck or needs to be replaced or cleaned.. now the gentlman who owned the car before me just totled around town it so Im sure it was never blown out the way it needed to be...also after the car wrmed up the OVP relay was very hot to the touch at one point I could barely handle it and spark is minimal at this time as well I think I needs replaced because it was hard to start after operating temp had been reached... the idle was a bit rougher as well.. there was no fuel smell around the distributor or the EHA so I think they are ok .. as I could push the plate down in the fuel distributor and revs picked up but only to a certain point before the engine stalled.. wich I feel is due to flooding with fuel.. as when the car is in its rough idle state the economy needle on the dash is all but in the red.. again this is in idle.. so anybody got a spare ICV and OVP relay for a 91' 560 sel for sale
Happy Fathers Day
