Hey guys over the weekend i replaced my oil pressure sending unit. And right after i replaced it my truck started to misfire really bad. So i checked the cap and found one plug about to fall off, so i fixed that. Now my truck still misfires but is intermittently. And today it has started to get worse. While at a drive thru today it started to run rough and it died twice within 5 minutes apart. I just put new plugs in it a couple weeks ago, maybe its time for a cap,rotor,and wires. Please help.
