Egg smell

[kineticz]

Hi all,
I've done a search and it could be coil packs, can't be the cat as I don't have one The smell lasted for about 1 minute and then went, the performance of the car didn't change, and no EML came on



Could it still be the coil pack? Perhaps this is what's been causing my drops in boost recently? (20 reduces to 12 psi).

Thanks

stop eating egg mayo sarnies all the time


could it be because no cat , nothings filtering the crap

used to have it on my old car with a 421 manii

[kineticz]

I thought coil packs, but wouldn't it bring up a dashboard light? I need to find out which has gone

Believe it or not......did you air con switch on after not been used for a while??

 

[kineticz]

No lol...

Well if it can only be either coilpack or cat then I guess it's the coilpacks, just scanned the ECU and no codes.

Binksys car done this recently to........he doesn't know what caused his either and he also has no other faults as I code read it twice in last couple of weeks

its usually the cat that makes that smell, ive smelt it that many times on MOT's.

 

[kineticz]

Is the cat smell caused by overfueling?

Strange the Adam. I expected the car to start misfiring, first thought was coil pack, but nothing changed

Hello mate,

Are you sure the smell was coming from your car and not the car in front?

 

[kineticz]

There was no car in front mate lol... It was out on a country lane so I drove for a bit thinking it was a farm, and it lingered for about a minute. It then hit me that my coilpack was about to go, but the smell cleared and the car carried on as normal, no misfiring etc

Is it possible that the car is running on three cylinders without misfiring?

 

[leonrob]

can you smell it when the cars stationary (engine off) if so it could be gearbox oil cause that smells like eggs

Its def your coil pack, this happened to mine and no light comes on, my thread about it is now a sticky.

well from having a decat will make this smell , because theres nothing there to filter any of it out , my old car used to do it randomly , youd then question yourself did i let one rip ,???i dont think so , lol

but i cant comment on other symptoms , being in a derv now ,

That would mean the coil pack as gone and you would definitely notice it.

 

[kineticz]

Hmm well the car didn't run different but I might change them as they haven't been done for ages

Phil any idea why mine didn't run any different when this smell occured? Could a failing coilpack cause loss of boost and poor mpg?

i had my car remapped at xmas and after 30mins of 'testing' it gave me that smell(which they warned may happen). i slowed and it disappeared. 2,000 miles later, never smelt it again, liquid guage results full power and no mis-fires.
But now you know why some people carry atleast one of these £25 coil packs around with em as do I, just in case.

Well after a trip to p torque and thinking my decat needed to be mapped again it turned out that the decat is mapped but it is the post cat lambda that needs replacing, so that's another £70
