To follow the rest of my problems with this engine ive got more probs
Run the car up to temp, idle drops lots and the EML comes on and stays on, also when pulling up to a stop the car will somtimes cut out (50/50 chance).
I flashed out 12 codes earlier before i had things to do. Bearing in mind this is a X16XE ecu (Another member had it on his X16 nova without a problem) with a superchip.
I reset the codes by disconnecting the battery overnight, and then ran the car up to temp/EML light on.
From the top.
0230 - Fuel pump - Never noticed it to be a problem
0325 - Knock sensor - I have a 1 wire one, but this ecu is from a later X16 which has a 2 wire one, this shouldnt be a problem as the 2 wire ones are just the signal to the ecu and a earth.
0335 - Crank sensor - Would cause the car to not start or go into limp mode?
0412 - Secondary solenoid valve - Part of the EGR/blower stuff, dont have any of.
0505 - Thx to google i found this: Idle speed control (ISC), system malfunction. No idea
0105 - Map sensor - Tested on another car/tested known working one, still same.
0113 - Nothing on top buzz again.
1231 - Fuel pump relay - seems to be fine, checked with another and same.
1405 - EGR valve - No idea why as its connnected so thought it would be fine?
1410 - Secondary air pump relay - Simply there is no relay.
1502 - Immobiliser control unit - Cant understand this one, not had a problem with it?
1640 - Knock control unit or quad drive module
Problem started when i took the engine out to do the crank oil seal. Only thing that i think i changed was tyding up the wiring.
Now then, i think that is all, any help is great. But looking at that list its got to be a couple of faults, not just one .
BTW its not lamba, as thats brand new.
Somthing that was suggested was a bad earth, going to check tomorrow morning but was too late by the time i sorted it all.
Any help is great.

if your getting that many, its probably a wiring issue
i presume the engine was running fine before the work using the same sensors
a bad earth seems to be highly likely, or a dodgy plug connection somewhere in the loom....

then again it could be a fault with the actual ecu, as it seems to be giving faults from all over

Yep, nothing has changed really lol. Off to check all the wiring now, and there is a chance its the ecu but meh, hope its not.
And no probs.
