hi again spoke to the company that did my exhaust they put on free flow mufflers
so i think it will be some other problem any ideas this ones realy got to me
got a rolling road on the 22nd so that might pic something up hopefully haha

 

Could be what tech said: tune up?
you said the last one was in April....How many miles since then. It might need a Tune up
Check the spark plug gaps, make sure they are within spec: Gap0.028- 0.032 in. (0.7- 0.8 mm).
If it is not that....Iguess techcan help you again.

Edit: Tech did metion it is a "normal condition" for manual trans.

 

hi all been to rolling road today my afrs are still showing up to lean, guy says as i fitted it my self the maf needs to be set back up with the ecu has anybody got any info on this .car prob done 4000 miles since last service
thanks roy [/align]

 

Im not sure what he means by that. Some cars you need to reset the adaptives but that can be done by removing power to the ECU for 10 minutes.

 

car still running lean maff is new so what other things can i look for

 

Vacuum leak or O2 sensor going bad.

 

thanks for that tech will try

 

another question what do they mean by callabrating the maff after fitting a new one
thanks roy

 

The computer adaptives need to be reset. Sometimes if they are not reset the computer will think the part has not been replaced and it will set the code again.

Either the special Volvo setup can reset it or alot of times disconnecting the battery will reset it as well.
Sometimes there is an ECU fuse as well if you pull the fuse and disconnect the power to the ECU it should reset it.

 

hi i tech
ive pulled the fuse before but only for 15seconds will try disconecting the battery someone said to touch + and - together for 10 seconds is this correct ,another question (u be getting sick of me asking questions ) i have a custom exhaust fitted cat back with free flow mufflers 2.5 " pipe, now i read in a post that your engine needs to be mapped for the exhaust to work wih the engine is this correct ,do you no ware i can get a (think its a lamda sensor or o2 sensor) for the afrs, for my s60 t5 2001 from and sent here
thanks again tech

You can disconnect the battery and touch the terminals together for 5 minutes and try that.

You should not need a tune just for the exhaust.

Are you looking for a guage for reading the AFR's?

If so they are like $400.00 or more. You need to have another O2 sensor bung welded into the exhaust and have a wide band O2 sensor installed with the system.
