1) vehicle engine has to warm up for several moments if stationery for longer than a few hours (regardless of outdoor temperature); 2) transmission slipping or pistons not firing while in operation-whether in town or highway; 3) if vehicle idles, engine shuts off and upon restart, has to reach 2000 rpms to begin be able to put it into drive. Vehicle has been taken in numerous times to multiple Honda service stations and independent mechanics with no positive resolution. Work done included: crank sensor, coil packs replaced, starter replaced, fluids flushed, valves adjusted. Codes pulled have not pinpointed the issue nor does any mechanic have an answer.
