Alfa 2.0 147 Selespeed Running Problem

Post by philip15 »

Hi there i have recently purchased the software and think that it is brilliant but i have got a problem maybe someone can help,
i have a 147 in my workshop that i have replaced the engine for a second hand unit all old stuff put back on so only the block and cylinder head has been changed,
The basic problem is rough idling almost like a pulsing, after a bit of info i am told it cold be the lambda sensors a couple of times it has come up with different errors but i feel it is due to whatever is the matter, i have actuated all the components listed in the fiat ecu scan and all seem to actuate except for the lambda sensor replay ( i cant hear it clicking in at all on either of the actuators.
But the biggest problem is i cant find the lambda sensor relay? i have looked at Autodata and tolerance (tolerance making the most sense of the fuse box layouts )
but i still cant find the relay in question PLEASE PLEASE HELP!!
Thanks
phil :? :?

I don't know about the 147 sillyspeed, but on older 2.0 16V TS engines, it's often powered by the same relay(s) that also powers the injectors, coils and fuel pump. Use a multimeter to see if it gets power that way.

Lambda and relay - forget. you have a problem with reseting. Do this 90 sec MAP -> 90sec OFF -> min 90sec. idle without clima, acceleration, ... lights
Do not forget to replay what is the result. Maybe you have one problem more but do this at first to see
