hi im new to this site sorry for jumping in ive got a seat leon although does have the 1.6 AZD engine my car broke down few months ago and wouldnt start andwhen it did it ran like a dog with 3 legs , so i took it to a garage who hooked it up to there computer and a number of faults came up includeding system bank 1 to lean ,voltage short to B+ (didnt knowe what that meant really), random misfire and a number of other faults including EGR and lambar so the garage replace my EGR and lamber clean my TB £750+VAT later my car was running perfect apart from running 0.01% lean at idle the garage decided that this is down to me having an aftermarket induction kit fitted which to be honest has been on the car 2 years and had no problems .
So one month later as i was going to Blackpool (ok i did hit 110mph at one point) my EML came on so called AA out and fault code came up sayin system to lean which id suspected considering it was lean at idle so must bit alot more lean at 110mph <so anyway had that cleared few weeks later EML is back on so i call AA out again fault now is EGR and lambda whish was replaced with Brand new parts direct from VW so had them cleared once again a few more weeks go by my cars idle start becoming erractic when warm to the point where it shake the engine and as describe in other post cutting out when steering applied ,only on certain days tho and after a long drive other days its fine o and EML light on again now im in a dilemma really my cat has decided to melt its insides so its rattling like a metal ball inside so need to have this fixed before i go back to the garage as i know they will prob put that as the cause .
My question is will my aftermarket filter affect this and what can i do myself to check this idling problem im sure it cant be EGR or Lambda as there new they have got 12 month warranty tho just in case
