Its only the first initial cold start in the morning where it struggles. The idle chugs up and down sometimes even stalling out for the first minute or less than as soon as it starts to warm up and everything circulating its smooths out and runs sound as a pound. Ive checked and cleaned TPS, MAF, checked all plugs, coil pack connectors, injectors are all ticking (havent ohmed them on account pretty new drop in kit from bernie.) The last thing "I" can think of is the IACV going bad? Need Cleaning? Or CAS needs cleaning/replacing? Havent had time to do that one yet. Any ideas? Thanks guys!
