Omega General Help / Multiple faults on my 3.2 omega? Help!
« on: 31 March 2021, 22:43:01 »
I recently got MOT for my omega while happy and pleased with myself as I done 99% of the work
On the other hand I’m not mechanical minded in where things are now I have 7 faults on my dash and I’m using my omega as my daily currently while I’m replacing the gear box in another
The fault codes read
P1111-4 intake manifold 2 open
P0420-1 catalysts system Efficiency below threshold(bank1)
P0520-2 catalyst system efficiency below threshold bank 2
P0300-1 random multiple cylinder misfire
P0302-1 cylinder 2 misfire
P0306-1 cylinder 6 misfire
Before I had the car threw MOT I changed spark plugs to NGK and got the timing belt , water pump and fan belt, done a lot of other work but that was the main work done on the engine I tryed to clean them already but nothing turns off if anyone could shine any light on now to go about sloving problems before I buy coil packs at 125 for a set, I would be greatly appreciated,
