ok here goes guys. my 99 audi a3 1.8t 20v is running rough and is really juddering/missing when reving. with a poor low idle. i have swapped a new MAF NO differance new spark plugs as old once were very black. NO differance. ive replaced the o2 lamba sensor, NO difference. ive also now replaced the coils and THERES NO DIFFERANCE. im wishing i kept my 17year old escort now lol.

this problem happened after i filled up with fuel and restarted. checked with station and they say there fuel is ok no problems reported. its shell at borne bridge ipswich.
