Hi all im nearly there in sorting my car, my last full tank it did 90 miles so more than likely lambda sensor, but 1st thing when cold it takes a bit to start pops a few times then starts but once started it starts straight away all the time, would this be all down to just the sensor..........

 

is check engine light on?

do the rad fans run when engine is cold?

 

yeah whilst trying to get it started the check engine light comes on once started and warms up when you start it again it goes out, ive tries unplugging lambda also and then engine light stays on, the rad fans are ok just come on when gets hot like normal,,,,,,,

 

reset the ecu to clear any recorded error codes.. then try cold starting it and then read the codes stored.. this would give an indication of the problem

reset and error code reading

You could read the codes before resetting it the first time but there might be some old codes stored which are no longer valid

hi, i dont know if this helps. but if u have a dump valve fitted try removing it and replacing with a standard one. As my car was over fueling getting about 100miles per tank, idling was really poor and my car would stall if i came to a stop after flooring it. i hope this helps.

 

i checked the ecu code and got 12 starter switch.....

 

do you know if the car was chipped or had an aftermarket ecu on before you had it?? If it was tuned it might have bigger injectors which will destroy your consumption. My lamda went, and coolant temp sensor and i will still getting 160 miles to a tank, long journeys too.

 

try these guys - central subaru there very good .
