Cleared the codes a few times P0130 is the most common code + P0301 or any one of cylinders coming up as a misfire P0302 P0303 or P0304. I cant understand why it backfires through inlet manifold and will not rev just dies when valve timing is ok and cam and crank sensors are reading ok. when it gets slightley warm say 30 to 40 degress on ect sensor it revs pretty well. This fault happens everytime without fail ie poor to start when cold ok when slightley warm + revs ok aswell :-/

But the others that appear when they feel like it are P170 lean exhaust P1700 svs request via can P0335 crankshaft sensor open circuit P0301 cylinder 1 misfire detected P0302 cylinder 2 P0303 cylinder 3 P0304 cylinder 4 all misfire detected Air mass meter was swopped for a known good 1 of a perfect running car. Ect senser reading ok when cold. Its really doing my head in i think engine ecu is f..cked ? PLEASE HELP !
