Omega Electrical and Audio Help / dimmer for dash flickering

« on: 03 April 2018, 10:42:49 »

Oddly enough this happened when giving the car a bit of a tanking, realised it was probably just the Gs doing it, but when you roll the wheel up and down it doesn't dim, just flickers a bit. Guessing need to take light switch unit out and give the pot a dash of WD?

Wee update to keep things rolling on my WIP. I've been posting various things all over the site but haven't updated anything here, so here we go:

EML light is now out. This came on when I'd filled up with costco fuel, I think this was a big coincidence, however it had me thinking could it really have been that. I came to my senses and thought no it can't be.

So at the same time, or just after this event, I was planning to replace the back end of the exhaust, well the back 2/3s as it was toast, mainly around the join to the tail pipe. I had hoped that maybe this was causing a problem with gas flow and that the code for 02 sensor was on as a result. Idk but a fair assumption at best.

I hadn't done anything else to the motor so I was fishing for other things that could have fired the code off.

Right about that time I also experienced a judder and at one point , a stall, when I was pulling up outside house. This happened a few more times so I was getting edgy now and had lost confidence in the reliability of the car.

This then led me to think that the crank sensor was on the way out as I had read on here so many times, so bought one of those, Gen GM one. I then decided to give the vac pipes and connectors another good look over, and the only thing I could perhaps suspect was the plug going onto the airflow meter bit at the front, which the plug bit that secures it on was broke. However this happened ages ago when I done the timing belt I decided probably not that, as it still felt secure in it place, and had no issues since last year. I got a tie wrap and secured it round the plug then tightened it so it would pull it right into the plug socket.

Immediately after this, the EML light was still on, so I decide maybe it was the exhaust sensor and/or crank sensor etc. I then drove down to my folks to drop off a few things, stopped for fuel on the way and when I restarted it voila the EML light was out!

I had heard that it can take a bit of time for codes to clear, so it must have been this loose connector. Just goes to show the carnage a loose connection can cause. Codes were saying one things but it was that. It also goes to show how that a code doesn't always mean that, and ironically, the code will only be correct if the whole electronic circuit is not breached in any way.

I checked tyres a few days ago as well and they were all around mid to low 20s, so bumped them up to 30, and fuel economy is also much better, and the car is running very sweet.

Omega General Help / Re: rust treatment

« on: 02 April 2018, 16:26:51 »

What are the recommendations on rust treatments I treated a small section on my wheel arch about 6 months ago and the rust is showing through again. I used Loctite rust remedy and cleaned as much rust off as possible.I know cut out the area and weld but this is a very small section.

Usually for small sections that aren't rotten just lightly grind off the rust with a grinder flapper disc, treat with a good rust treatment product, then wash down with clean water, thinners and apply a good few coats of primer and finish with top coat and lacquer. Usually it will come back in time though. I do find the more coats of primer the better. I've been doing repairs on a project I have stored up and one bit I had put about 5 coats of primer on new metal, the other bit only one coat, the one coat bit was rusting after a couple of months. The other bit was fine. Mind you primer is not waterproof so get a top coat on as quick as you can if you are using car out and about.

If my understanding is correct aren't road surfaces about 90% rough aggregate, shredded glass and the tar is just a "glue" to hold it all together. I think they might be using cornflakes and weetabix as the aggregate now!

Its not even just potholes, whole roads are wearing away because they dont use high quality tar and relaying procedures, they just rough the surface up and put a light skim of crumble mix over the top. The stones are tiny in it, they wash out and cars goin over them doesn't help, add in rain, frost and all the rest and you end up with the old road surface "resurfacing" after a couple of months.

Also have you noticed how many blocked drains there are. The councils dont clean em anymore, they dont sweep the gutters in autumn either, adding to the blockage problem.

Presumably the fuel pressure regulator vacuum line is still connected to the bottom of the throttle body?

That is the pipe that comes along the middle of the banks and plugs up the way into the body, if so yes I've checked all the vac lines all around there and on the multi-ram bits as well.

I don't mean to be rude, but if you don't know what a MAF looks like or where it is, I'd probably get some help.

Anyway, as well as the above suggestions, look for split pipes (air to plenum) and split vacuum pipe end. Also, it is worth checking the throttle body to see if it's gunked up.

It's no prblem i know where it is. I just put that all back together last year after doing timing belt. Everything looks fine but will check agsin. If i dont see anything obvious what is next step with maf?

if you had the tech, tools and experience you could examine how well it is functioning.


As you don't have those, disconnect the electrical connector on the MAF, and drive the car. This will put the EML on, but if the actual problem is no longer present then buying a quality new MAF is your next step.


But you're already breaking the first rule of diagnosis by not going back over the work you did before the fault.

If you mean the timing belt work, that was done about a year ago and have checked this area multiple times, and once more tonight.

Going by this advice I unplugged the maf multi plug (the one under the left air intake bagpipe thing right?) and the car struggled to start and when it did the gearbox seemed to lock into a high gear and it wouldn't move. So I guess that didn't work either. I then plugged it back in and the car ran fine.

I have a friendly contact in the AA who has said that he can check it. I don't know if this will give a diagnosis or just codes, but it won't hurt, my 2nd option is a guy who does tech2 near Glasgow. I will take it there and see what if anything they can find as this is doing my brain in now.
