Hello I'm new to this site and would like to introduce myself first. My names Mike Kimble and I own a 1997 Dodge Ram 1500 5.2 liter Magnum Brown. I live in Shelby Township MI, and I am 19 years old. I have had my check engine light on for about 4 months now and went to Auto Zone to get it checked out. I have cylinder misfiring in cylinders 8,5,3, and 2. Could this be fixed by just a tune up?? also I have P0441 EVAP, small leak/ no flow condition. I have no idea what that is so if you could please help. Also have ASD Relay voltage at PCM. Again no idea whats going on. My grandpa usually fixes my truck but hes slammed right now with work so I am going to my auto shop I went to in high school to try and fix in Monday. Can someone please help with this problem?? Also have a problem with my heat/ air conditioning, when I am driving and hit like 4,000 RPMs my air goes from my face or wherever its sopposed to be going, and shoots up through my defrosters... I love my truck and don't want it to die!!! please help me!

 

Tune up (cap, rotor, plugs, wires, etc.) will probably fix your misfires unless they are fuel delivery related, whens the last time you tuned it up? Seems like quite a few misfires

Evap leak code sometimes pops up if you dont screw your gas cap on tight enough (its a pressurized system), or could be due to hole in the lines somewhere/bad hose fit.

If you pop the hood, you should see a white sticker on the rad crossmember that details the evap system. Checking for leaks in the system manually is tedious, but it costs you nothing; alternately, you could take it to a shop and have the system smoke tested (no idea on cost, i found mine the hard way).

For the vent/defrost problem, do a search here for "wild vents", thats a pretty common issue that has been discussed here many times, and is usually due to a vacuum leak (or so I believe).

ASD relay voltage could be due to a bad ASD relay (located in the power distribution center under the hood on the drivers side).

Good Luck, and welcome to the forum

 

Did some of your homework for you on the wild vents problem. You might have to search through many pages, but the answer is likely in this thread: https://dodgeforum.com/forum/2nd-gen...ild-vents.html


EDITED to add: Your evap and wild vents problem may be the same issue.

 

thanks a lot im going to try to get a tune up tomorrow, do you think it may have something to do with the timing chain as well??

 

An issue with the timing chain should give you other codes and you would defiantly feel a performance issue. My truck did the same thing when I first got it, misfire on cylinders, 8,5,3,2, random misfire and all I needed was a cap and rotor. Start with the basic tune up, plugs, cap,rotor, wires and if your truck has over 100,000 miles on it I would also consider a new ignition coil and adding fuel injector cleaner to the tank. You will need to have someone clear the codes when you are done, then drive it around alot and see if the codes come back.

 

Easier way to do this is to just disconnect the batt, turn the key to the on position (not start!) and let it sit for 1 min. Then reconnect the batt. This resets the pcm entirely

 

Let me make sure I understand what you are saying. Do I leave the key to the on position while reconnecting the battery, or after a minute turn the key back off and then reconnect the battery?

 

Its safer to turn the key off before reconnecting the battery. Both ways would work though.
