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

I was thinking o2/lamba poss ht leads or coil pack?
Has had a recent MAF

 

anyone?

 

forgot to mention have just put in a new gear box and radiator. did an ecu check have got codes 12,13 and 21 not sure if these have gone or are stored from previous

 

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

cheers im thinking most likley the coolant sensor due to previous posts

 

changed coolant sensor didt make any differance any imput appriciated

 

did you reset the ecu after fittng it?

 

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

 

cheers no didt re set the ecu, have got a turbo smart dv but the bung has gone missing could this cause the problem?

 

The bung in the recirc pipe?
Your having a laugh right?
Of course it will cause this issue lol.
Best check all wheel nuts are on whilst at it

 

 

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 )

 

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

 

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

Simon

 

Always see the funny side mate (although a half price map would make it easier lol) thanks for the help just wish i hadt spent £40 on that new coolant sensor at least its one less thing to go wrong

 

Touché! Great reposté.

 

 

Yeah, and i feel hurt inside for you garry, so i may need the map im having with you jgm reduced to!

 

put new bung on did ecu reset is abit better but still ideling all over the place once upto operating temp. have ordered a new lamba if this fails has anyone got any sugestions? Thanks

 

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.

Simon

 

Coolant temp sesnor?

 

well remindered.

do you have any error codes now?

 

yeah stilll got the old maf will try that aswell. have put a brand new cooant temp sensor in. seems really strange that the cars fine until upto operating temp. thanks

is it worth getting a obd reader?

 

is the engine light on?

 

no no engine light

 

so you have no error codes to read then..

Simon

 

No no error codes are coming up since i put the coolant sensor in and reset the ecu

 

Tried new lamba today still no good. cant decide if to go down the icv route or leads and coil pack or send it to a specialist. Thnks to eveyone for their help and imput

 

im in the same boat mate.
