low idle and water disappear
Hello,
I read alot on this forum to fix my car but after couple days I don't know what to do now.
Engine do not keep stable rpm. When I set 1000rpm stop engine for 10min and start again it will go on 500rpm, when its cold (its not so cold at night here) its starts and keep 2000rpm until it worms up and going down and usualy stops.
I cleaned throtle body, checked TPS, set everything correct but the engine wont keep low idle when throtle is open according to spec, I had to open throtle more than it should be.
No error codes
all sensors OK, I checekd resistance and volts ob ECU according to manual, everything OK.
Compresion 190psi (two cylinders are diferent 180 and 200)
Spark plugs has the same colour, checked in other car.
spark cables resistance checked and OK, distributor cab looks very good.
No vacun leaks (I found that its not so sensitive on vacum leaks.
After one hour of testing engine(no driving) one liter of water disapeer, there is no smoke from exhaust.
I have no idea what is going on
PS.
Sorry for my english

Have you checked the oil to see if the coolant is in there? Could be a head gasket as they don't always leak out the exhaust. I'm guessing that the radiator, heater core & overflow bottle are not leaking? First thing you need to figure out is where the water is going. Other than that I'm not sure what to say. Maybe someone else can help more.
