I have a Volvo 940 2.3 petrol 1997, turbo,in was told it had been chipped, IT keeps on cutting out and its getting very tiresome coming home via the AA,so far my loical Volvo agent has replaced the relay for the fuel pump that's sits behind the ashtray, replaced the ignition amplifier that's sits on the inner wing by the front nearside h/light, a new dizzy cap and rotor, a new coil, and after one half hour of driving it conks OUT! its going back in to have the crankcase sensor replaced,if that does not work they are hinting at the ecu?? I have thrown so much money at this motor trying to solve the problem,When it gets hot that seems to trigger it,is there a possibility the chip could be at fault? has anyone got any idea how the problem could be diagnosed,the Volvo people have had all sorts of computer thingys plugged and NO faults are recorded, really fed up now, and the motor is to good to junk

 

Symptoms sound like a failing CPS. Keep your fingers crossed.
