Cold start problems
#2
Is it an ongoing issue, or just start with this load of fresh fuel ?
Quick simple would be to just run this load of fuel out and try different store.
Could be a residual fuel pressure problem, system not maintain pressure for period of time (heat soak/fuel boil in rails over hot engine), vapor pressure level of fuel, hopefully you did not fuel up with E-85... NO NO on a Hyundai.. fuel pump not supply pressure quick enough.. lots of variables.
Less than 60,000, take it in for inspection. PCM Update for cold start/rough idle and misc codes available,, program #170........
