and multiple cylinder misfire? i have changed spark plugs,plug wires,distributor cap,rotor button. i used champion plugs and the most expensive wires that slacks auto parts have. iv had the fuel injectors and catalytic converter checked. the van runs great the only thing is it sometimes has a rough idle it idles up and down a little. here is the freeze frame maybe it will help. DTCFRZF- PO301, FUELSYS1 OL, FUELSYS2- N/A, LOAD_PCT(%) 6.3, ETC(*C) 86, SHRTFT1(%) 0.0, LONGFT1(%) 0.8, MAP(KPa) 11.2, RPM(/min) 832, VSS(Km/h) 6
