Vehicle will not idle when cold, runs OK after running for 10 min, no fault codes present, fuel pressure OK, scope pattern of fuel pump OK and running at 6 amps, air mass meter showing as 1.9v at idle when warm and 4.6 v at full throttle and response time is good, have substituted throttle body still bad when cold, live data readings for temp sensor when cold read close to outside temp,any help would be most appreciated
