Any help appreciated. Car feels fine until is fully warmed upto operating temp. The idles and spluters/occasionally stalls once warmed up. Slight smoke and rich fuel smell it feels kind of like a missfire. its a 99 rb5 Thanks

Has had a recent MAF

If you reset the ecu and the codes go then they are previous ones.
Worth having a look at the leads/coilpacks to see if they need replacing and have a look at the plugs whilst you at it.

12 is stater signal
13 is camshaft position sensor
21 is coolant temp sensor

Unplug the lambda sensor and see if better after a drive.
Check dump valve not open or for split pipe, pipe off

I was waiting for something like that from Simon, after seeing OP's last post!

(Would be nice to know as much known info as poss before a successful internet diagnosis can be made )

garryrb5

apologise for my stupidity (and bad Spelling) lol. where can i get a new bung?

Jolly Green Monster

lol.. glad you seeing funny side too.. was worried after posting you'd be annoyed.

Quickest option to get you out of trouble is a screw driver handle and a jubilee clip..

not sure where to get a bung from.. ebay perhaps?

Simon

few options on there

dump valve bung, Cars, Parts Vehicles, Subaru items at low prices on eBay.co.uk

you mentioned changing the maf.. was the other maf kept and was it totally dead?

I wonder if the lack of bung has killed the maf.
