quick question for anyone in here who may have had same problem. my truck (97 c1500 5.0L) started having a weird issue where it needed to warm up at least 15mins before driving or it would miss on all bank 2 cylinders and prevent throttle response and shifting until it got up to temp, it just did it again but this time when i was about halfway home and all the way till i got home, but was idling fine when parked. all wires, plugs, cap and rotor were done less then 5k ago.also only has the 2 upstream o2s. im stumped and dont know where else to go. any help appreciated!
