After sitting for a few hours it will run rough for about 20 seconds then straightens up and runs fine. Getting worse and now throwing code multiple cylinder misfire. Within a week I have cleaned MASS airflow, replaced MAP, replaced fuel pressure regulator, replaced fuel filter, cleaned throttle body, and was time for new air filter. Did plugs and wires and cylinder 1 coil pack 11 months ago. About five months ago had to replace everything with the belt drive system (harmonic balancer, water pump, altenator, power steering pump and pulley, compressor pulley bearing and clutch, tensioner, and idler pulley's). This problem started about a month ago and has haunted me since.
have the same problem?
