Hey
My '89 Lude failed emissions. I serviced it and replaced some vacuum hoses and it improved but not quite enough.
I got it nice and hot for the test.
I added another gallon a fuel and dumped a whole bottom of Redex in.
Are there any temporary methods to help - other fuel additives etc?
The car has been sitting for 3 years and my MOT centre is just around the corner so its not like I can take it for a motorway blast either..

- replace coolant temp sensor
- remover injectors and run through a cheap ultrasonic bath
- clean egr valve and TB
- remove o2 sensor and gentle lclean off carbon deposits, hwowver, its a good bet that the sensor is knackered anyway

No idea what an 89 lude is ? lucida ? does it have a cat or egr, new oil and plugs will help, if it has a cat it needs to be up to temp before going on the sniffer, you also need to burn all that redex off as that will make it fail the test till it's gone through and done it's job (the mix is now way to high), it will still clean what it cleans but wont burn clean.

Are you sure the MOT center is competent and testing it as a pre 92 car?

I was watching an old Wheeler Dealers episode the other day and they used a fuel system decarboniser on a Jag XK8 - I think it was a terraclean one and it brought the emissions down pretty significantly - maybe worth a google see if anyone near you does it?

fresh oil , fresh air filter , new plugs
id drop in some super unleaded , maybe book a test at a further away garage(even if you cancel it) so you can go on a proper good run , get it up to temp and use the gears and give it a good thrash to blow away the cobwebs
take it straight into the mot from the run

Change the oil. Also if its running an aftermarket cone type filter change it for the standard airbox.

Pull the probe out of the exhaust whilst exclaiming how clean the emissions are, Forte injector cleaner as well helps

I replaced the plugs and wires but it is running the old oil.
Would just an oil change really make much of a difference?

If its burning a bit of oil, its better to be burning clean oil!

Hi, changing the plugs and leads is not servicing it. So I would suggest changing the oil, oil filter, air filter and fuel filter if fitted. You have put enough Redex in for a tankful into 1 gallon of petrol and then in the car. So I would suggest draining the tank and putting 2 or 3 gallons of fresh fuel in (you can put the drained fuel back in after the test and fill up) Three year old fuel would have had an octane rating of two ron. Plus oil of that age will be like sludge so warm the engine up and drain the oil hot it will come out a lot easier.

Would just an oil change really make much of a difference? it could yes ,if the car has been moving about alot on choke then you can get fuel in the oil , with regular use getting up to temp it would burn off and sort itself out , but yeah old stale oil fumes comeing through the breathers wont help infact ...any airbox breather pipes you re direct for the mot? prob just needs a damn good run to get the old petty out of the system |

Thanks - I will run the car until the fuel has been used up and the redex done its job. Followed by a fresh couple gallons of 97 octane fuel. I have just been on opie oils and ordered some oil and filters.
