172 sounding like suburu and smelling like socks

[rich19]

hey guys would like some advice/ solution!

on the way home after taking a very slow corner as i started to accelerate the exhaust sounded like an impreza with a deep burble!! when i reached home the dash light (the one looking like a transmission symbol) started to flash

also noticed there was a heavy cataytic converter smell so my first conclusion was manifold or catalytic issues


any info would be greatly appreciated

missfire?? overfueling?

 

[rich19]

i`m guessing definately over fueling but would a manifold/ catalytic issue cause this??

 

[powey]

coil pack? not igniting the fuel correct therefore throwing it into the exhaust system

 

[rich19]

powey, anyway i can check if this is the problem without replacing it?

 

[Hutchie]

just to add, iff the lambda is not working it will add too much fuel

Your socks smell of eggs?

check your spark plugs/leads.

i had this and my head had forced my spark plug out and was making a subaru noise

Eurocar parts do a basic coil pack for around £30.....not horrendously expensive to test and works fine (my 182 ran perfectly fine with it)

Fail that, have a look at the spark plugs and check they are ok (not blackened) Again, eurocarparts do a universal plug that is about £5. It will run like its powered by coal but lets you know if the plug was at fault.

read my post^?

HT leads are £80 odd for decent uprated ones from KTR.

Injectors...pass

UPDATE GUYS!

just replaced the spark plugs and it appears to have solved the problem

the engine light is still on though so was just checking if this indicates another probem or will it take time before its goes off


cheers for all the posts guys

It needs the fault code clearing I would imagine.

Wouldnt bother the light will go out after a 100 miles or so, It will just be stored in the memory, So if it gets plugged in in future they will see the fault
