rac came out plugged machine in and came up with
p0170 exhaust lean
p0136 02 sensor circuit low voltage (bank 1 sensor 2)
p0335 crankshaft sensor incorrect signal
p1525 limphome position error
p1550 electronic throttle control engine stop
p1612 immobiliser no or wrong signal
p1613 immobiliser no or wrong signal.
said to me if i change crankshaft sensor most of the other problems should sort themselves, so i changed crankshaft sensor yesterday but as soon as car got warmed up engine cut back out and wouldnt start, sat with bonnet open for 1/2 hour to let engine cool down and car started fine, runs well when going, what else could it be and what do i need to do or purchase to sort this so car runs and starts when warmed up, this is my partners car and having a disabled daughter this is a nuisance, all help and advice will be greatly appreciated, thanks all.

You need to book it in to a garage with equipment to look at the parameters and see what,s not happening when the fault occur,s it could be any number of thing,s. A component or sensor issue or possibly catalyst issue,I would try to see the issue rather than just replacing thing,s.most of those codes are as a concoquence of the engine turning over but not firing up.
