hi ive got a skoda Octavia mk1 vrs ive had it remapped by a company shortly after I got it remapped the asr light came on then eml light came on so I scanned it and code p010203 came up. so changed the maf metre for genuine tps one  the  ran fine for a while then now under full acceleration at 80 to around 100 mph it hesitates backs off then powers up again but more to my concern is the asr light comes on and stays on till the car is switched of then it goes out. im not to bothered about the problem but I am selling the car soon and want it to be right. im just wondering if anyone had the same problem or knows something I don't thanks in advance

If you're selling it then take it back to where you got the remap done and get it put back to standard.  If it was working fine before the map then there's the problem.
