cold start problems/ rough idle
I just got this dodge less than 3 months ago, and up until recently ran just fine, then about 2 and half weeks ago, right after i did an oil change, it wont run right cold. it takes longer to get it going, and once its started it wants to stall and misfires slightly. but once it warms up it acts fine, all the power and everything. someone told me it mite be a clogged IAC, but i cant tell. help would be appreciated greatly.

There's a DIY for cleaning the iac. It's quick and easy as long as you're careful and don't move the plunger. It's worth a try because its free
I don't think that's your problem though
Reset your PCM by disconnecting battery and letting all the electricity drain from the system.
Sometimes you get lucky and that fixes electrical gremlins

Ill give that a definite try. thanx. i did pull off the throttle body tho, and i should probly mention that my oil breather at one time puked up oil through the air filter. destroyed my filter and had to buy a new one, but the inside was black as coal and gunked in every nook and cranny possible. im still cleaning it, and when i get done ill give a shout.

if the air filter clogged up, the IAC port might have gotten it too. note the TINY little hole in the bottom of the well. clean the well and the pintle of the IAC, but don't push, pull, twist the IAC. maybe even just replace it. about $40-50 at local parts stores.
replace PVC valve and clear the hose to make sure its venting crankcase pressure.

Ok, i cleaned the throttlebody till it looked new. took off all electric parts and cleaned them as well. replaced the gasket, and bolted everything back on. runs much better, but still has a slight hard start when cold and a slight misfire cold as well. On one of these threads i read that these trucks dont like platinum plugs in the magnum, which mine has, and being they are old perhaps just finish with a tune up. and im a little new to these newer trucks, ive only ever had pre 80s dodges, wheres the pcv valve located on a 5.2? and thanx for the welcome
