Have 1999 dodge 1500 Running rough will not stay running. Replaced ignition coil, plugs. Codes read to replace #’s 1 & 8 fuel injectors so I replaced. Run till it warmed up then started running rough idle and dies. Replaced fuel pump 8 months ago. What should I check or do to solve this problem?
Don't just replace parts till ur sure its the issue...get a scan done. Cud b bad ignition module or distribute...idle air control problem...or fuel pressure regulator
You read the codes so what were they exactly? That is only half of the issue. You can have codes that are showing up because something else failed. There is no code that says "replace injector"

Is this a 5.7? They are notorious for intake manifold gasket leaks. When mine did it, the diagnostics blamed it on an ignition misfire also! Replaced the gaskets and it runs smooth!

sounds like your egr valve is gummed up or bad. this is located behind the throttle body and has a single vaccum tube connected to it. if the diafram is still good you can remove it and clean it with WD 40 until the plunger works smooth

injectors may dirty run a pint of marvel mistery oil in a tank of ethel gas in your truck
