Have been more problems since last post. Engine now runs very lumpy on start up, engine rev drop between 1000 and 500 until warm. Eml on sometimes and off sometimes. Engine does cut out occasionaly.

The gears seem to change up and down different to how it used to. Could this be due to the faulty crank sensor?

Goung for test on tuesday, just trying to get some undertanding whats going on.

Hi Omegalyn,

Thanks for your reply. Was very informative and gave me some idea of what was involved. When I was younger I used to do all my own repairs, but now find it easier to get someone else to do it if I can afford to. I have today had a quote to do a diagnostic check for £25 to check to make sure of the fault and fit a crank sensor for £35 labour. I think it might be worth the money to have someone else do it. It is being done at an auto electrician who has been recomended to me.
The car runs really well apart from the eml which is sometimes on and sometimes off.

Thanks again

Have got a fault code 0335 crank sensor from paperclip test. I need some advice on sorting out the problem. Is it just needs a new sensor? If so is it possible to fix yourself or is it a garage job. Have not got haynes manual yet as the car is new to me so no reference.

Thanks

Hi, Thanks for your reply. I took my car into Vauxhall last week and they did a diagnostic check and found no faults. That was £57.50 gone. Because of that they checked the spark plugs. They said there was water by the plugs (not in engine) and they were the wrong plugs. I have had the car for 10 months now and have had no problems with starting or running. They said that is all they could find. They changed the plugs dried up the water and

Success problem solved

Thanks to all and hope this helps others.

Great forum

If the cat was blocked would that not make the engine uneven when cold also?
Have also seen on ebay a tech 2 interface and software. Does anyone know if these could check things like sensors or is it just a code reader or are they the same thing.

Someone mentioned that you get a smell like rotten eggs if the cat has gone. As I said before there is a smell especially on start up.

How do you check the cat? How do you bypass thecat to check?

Thanks

Could anyone tell me how much the coolant sensor is and are they simple to fit? Would it be worth changing this anyway? I have someone coming to do a service on monday and change all filters etc,
Just going to check car now.

Thanks again for all your replies. When I was younger I used to work on cars with my dad since I was 5 (now in forties), I was very used to old technology. Fourtunately over recent years I have had reliable cars and not had to do anything to them. The omega seems very complicated and without the right equipment very hard to find the problem.

A very good point from grumpy, he mentioned about sensors and mixture and one thing that did cross my mind is that when I first start the car up there is quite a strong smell like petrol, although this does go. Also my back box on the exhaust has gone (the pipe at the back of the rear silencer has come out) could this also have something to do with it? Saying that the exhaust has been gone for a while and not given me this trouble. Going to have a look at the car now and will get back to you.

Have a nice day!

Have just changed the fuel filter (thanks to maintenance guide which was spot on). It seemed to be better but still got problem. I think I was hoping it would be a cheap quick fix. Going to check the oil in the spark plugs wells tomorrow. Still would like to know which is the coolant temp sensor that goes to the ecu, can anyone tell me?

Thanks

Fuel filter never been changed by myself have had car for about 9 months. As I have not needed it before can you tell me where the filter is? Also would this affect the running when cold or hot?

Checked paperclip test again, but no fault showing. Still got problems. Have found that car always starts first time and runs for about 4 mins then problem starts. It seems as soon as engine gets to running temperature a sensor kicks and the the engine starts to run rough. It will not pick up even under no load. While the engine is stil warm always has this problem even if you turn engine off and restart. If left to cool no problems. Grumpy says it could be coolant sensor that goes to ecu. Anyone tell me where it is. Would anyone be able to find this fault on a diagnostic check?

Thanks

Thanks for your replies. When I had my last problem, I had the cam sensor changed along with the cam belt and pulleys. All seemed to be running fine until recently. As I said the car starts first time and idles fine, after about 2 to 3 miles is when the problem starts. It is like the engine wants to rev but cant, the engine will not rev even under no load. No eml light and no coolant loss. Will do paperclip test and getback.

Thanks

Have had a few problems with my car which with the help of the forum have been sorting them out, now I have another one. Over the last couple of days my car has started to run really rough. It starts fine from cold but seems that as soon as it starts to get warm it misfires and does not run on all cylinders. When hard on accelerator the car will only do about 10 miles an hour if that. Is there a common fault that I should check? Any other ideas would be appreciated.

Thanks
