hi all I am having problems with my 2002 fiat siena and I need help to determine what the problem could be. My problem is I can start the car it will run and accelerate normally and it has and excellent idle. but it only works while engine is cold as soon as the engine reaches correct operating temperature it will stall as soon as you touch the accelerator when it fails the car pc deactivates the relay that controls the fuel pump and ignition coils it also gives me the following errors:
p1325 knock sensor
p0351ignition coil1
p0352ignition coil 2
p0170 self adaptive parameters
P0230 failure in fuelpump relay
u1600 electronic key
u1601 canbus error
any one have any ideas? or give me any advice?
ps it is a 2002 fiat siena elx 1.6l 16v engine and a magneti marelli iaw49fb.t2 ecu
