First make sure you have coolant in your radiator.
Pull off heater core hoses and connect a garden house to the pipe and flush it out.
Check vacuum lines by the heater core hose.
For a 2009 Ram, Yes.Try experimenting with the AC/Heat Controls. I have noticed when defrost is on there is a miss in the acceleration, but when the floor heat is on, the acceleration is okay. I am taking mine in to see what they say about this. My 2000 Dakota had a miss in the acceleration but the dealerships could never find the problem (or did not care).1973 Dodge Coronet (318 Auto); 1993 Dodge Dakota Sport (3.9 Standard); 2000 Dodge Dakota Sport (3.9 Standard); 2009 Dodge Ram (4.9 Auto)...Things have been going downhill ever since I brought the 2000 model, and am not happy with the 2009. Needless to say, this is my last Dodge.
it might have a sticking thermostat.
A possible cause could be that you have a clogged heater core.
check coolant level
Sorry bad news Your heater core has a leak
It's okay we found out from trial and error. We just flushed the rad several times which removed all build up that was causing the problem. The heat works like brand new now.
The coolant is low, probably from a leak. You need to have it checked with a pressure testor.
Check coolant level in rad on cold engine. If low you gort a leak. If level ok, replace thermostat and gasket
Yes, replacing the heater core should slove the problem.
Its your Heater core if it smells like a syrupy sweet smell if not then its your thermostat
It might, but not guaranteed. If there is a cabin air filter to begin with, and the old filter is very dirty, a new one will likely allow better airflow.
To lower the front easily you can heat up the spring in one central area (do not heat the whole spring) with a torch and the weight of the truck will slowly lower it. Once it starts to lower immediately take the torch away. If you want to lower the truck further repeat this procedure. Unfortunately, there's no easy way to lower the rear end. You'd have to replace the whole entire leaf spring
