Omega General Help / Help with action re. codes, please.
« on: 06 August 2017, 19:28:42 »
May I request some expert opinion and/or suggested action re. the following codes, please?
Both the pedal trick and my cheap code reader come up with these codes.
0100
0150
0155 According to the guide these refer to O2 sensors and MAF which I presume account for the MIL being permanently on. I'll have to tolerate the O2 codes for the moment but wonder if the MAF code can be eradicated and whether it would affect the points mentioned below.
0300
0302
0304
0306 These are misfire codes and probably account for the following. From a cold start the engine fires up fine but then stops accelerating briefly and then suddenly roars away normally. (like a rocket in fact). It can happen several times during the first 1/4 mile but there is then no repeat during driving until after a fairly long stop. During these hiccups the MIL flashes for approx 10 to 20 secs., presumably registering the misfire codes,and then returns to its constant display.
I'm going to change the spark plugs and possibly the 2,4,6, bank coil pack as the prime misfire suspects, but I don't know whether the MAF code would have any contributory effect on this symptom.
Does this sound like a sensible 'trial and error' procedure before considering a change of MAF? My son is taking the car and tin tent to France at the weekend so I daren't try anything which might immobilise it.
Expert comments would be most appreciated.

I think he must love me. 
The cooling system has always been well looked after with correct anti-freeze so I don't think I'll do the thermostat and transfer pipe on this occasion. My only experience of this job was at a meet at Timbuk's place many years ago when I watched Hotel21 struggle for two hours to remove the transfer pipe from Kate's Omega, having to resort to brute force in the end. But thanks for the suggestion.
