I flushed the tranny. Dropped the pan, replaced the filter, my husband decided to put a pan gasket on (the original install just had the liquid gasket). I pulled the throttle body off yesterday and cleaned it out (gross) and cleaned off the MAP sensor. Only change is that now I'm getting better gas mileage. It hasn't stalled, but it has come pretty close (RPMs down to like 200) but popped right back up and it still fluctuates when I come to any stop. I really don't want to nickle and dime myself to death here...thinking I might have my fuel system pressure checked?

 

okay...so I started stalling again. Also my Durango sounds like its missing again. I am still getting awesome gas mileage (since cleaning throttle body and all). RPMs still drop when I come to a stop, but not at every stop. I'm ready to throw my hands up. Someone suggested having the fuel pressure tested, possibly a bad fuel filter. Unfortunately, again, I do not have a seperate fuel filter, it is part of the fuel pump and the whole unit would have to be replaced. I would think, though, that the problem would always happen if that was the case, not intermittently like mine is doing? Anyone have any more suggestions?

 

Please keep posting, I have a 4.7 2006 dodge durango, and I have been stalling at stops, I also recently dropped my tranny pan and changed the filter, did you check the filter install? I was wondering if that was the cause of the problems

 

@ firsttimedodge...You maY be able to troubleshoot yours a little better than mine. the 4.7l engine has many seperate parts that my 5.7l hemi does not. Throttle position sensor being a big one. Right now I am thinking that I have a fuel pressure or delivery problem. I have noticed that when I run the ac, I do not stall and the rpms dropping is not as severe. checking around to see who can do the best job testing this.

 

Have you tried the idle air control valve?

 

Unfortunately with my particular motor (5.7l Hemi) the IAC and TPS are part of the throttle body and the only way to replace them is to replace the entire throttle body. At this time I do not have the few hundred dollars to spare to "see" if that fixes it.

 

You should be able to "carefully" clean the hole for the IAC in the TB.
