lambda

[cresswell22]

alright had a problem with my mk3 ibiza .Went it a garage for new lambda when i got it back .It felt really slow .Have put up with for a few months now .Was speaking to a guy at work he said when a lambda is changed they need to do something with the ecu like remap it or something is this true

 

[cresswell22]

what do you lot think

 

[cresswell22]

really do need some answers guys
before i take it somewhere

Is the car remapped already, ie revo,jabba,cc etc?
It could be one of many things, faulty maf etc too so get someone local to run vagcom on it first, itll cost you maybe a pint or a bacon sarnie!

 

[cresswell22]

no i dont think it has but not sure it has a new maf because they said it had . had it

 

[cordobabrendy]

Get to a local meet and ask someone to run vagcom on your motor then mate, if theres a problem itll usually show up as a low reading or an error code.

I'm sorry, i dont understand that!

Does it have a remap?

Do you mean it has a new MAF, or you dont know if it has one?

Post the spec of your car mate, so people know what they are looking at.

Need to give people all the info, if you want a quicker response.

Try unplugging the MAF!

 

[cresswell22]

right when i got the car it was quick so it might of had a remap i have not got anything to compear with so not sure if it has a remap all i no is that it was quick before the lambda change and new maf
witch is why i asked does the ecu need anything doing to when a lambda is changed as the garage my not have done it

 

[Olly20VT]

No it does not need mapping or anything like, i have change my MAF and lambda probes and neather made it go slow and i didn't have to VAG-COM it. if anything it should go faster because its got new parts in it. i would surjest that you do VAG-COM it just to clear the fault codes but this would not change performance.

Have you got a boost gauge? If so, if it is only boosting to 5 psi the car is in Limp mode and something is wrong.

 

[cresswell22]

yes got boost gauge it goes to 0.5 bar

 

[gavthelad]

there is 14psi to 1bar.........0.5bar = 7psi..........= standard

 

[cresswell22]

also when i start it up it is fine leave it sitting there a few minites and i am getting alot of smoke with a strong fuel smell what could corse this

 

[cresswell22]

Is this when the engine is cold or warm?

that doesnt sound too good.......what colour smoke you getting? If its got a nice bluey black shade to it your burning oil and it could point to an unhappy turbo.

Failing that......if the smoke runs clear after driving it, you may find it to be the valve stem oil seals, when you leave your car overnight the oil will have chance to seep down....hence the smoking on start-up.

 

[cresswell22]

it seems to be really white with a really strong smell it dont smoke on start up is starts after a few mins after i drive for abit it goes

 

[gavthelad]

have you checked the usual symptoms for a knackered head gasket?

 

[cresswell22]

no i ant checked anything how cound i tel if it had had it

 

[gavthelad]

the usual sign would be loss of water.......water in the oil (check in the oil cap).......running lumpy........white smoke.
