Rough Idle, Stalling, Misfiring.

[SJohnson]

Hello,

Recently I finished a full tune-up for my 1999 Ram 1500 5.2L 4WD. Replaced the Ignition Coil, Cap and Rotor and rewired all of the plug wires/plugs. Now my issue is finding the Crankshaft and Camshaft sensors, I believe one is near the back of the motor, by the tranny bell housing, but can't seem to find it exactly-seems to be tougher to find on the 5.2. As for the Camshaft I have no clue.

Hoping the replacing either one or the other will or both will cure some of my stalling/misfiring issues. When it starts it sometimes doesn't like to start until I try cranking it like 5-15 times, then sounds like **** when it starts. Roughly 10-15 mins later while running it shuts itself off and then will not start right back up. So I figured I'd start with the Crankshaft sensor.

Help would be appreciated. Thank you.

sounds like a similar issue I had on my 01, I replaced the crank (if you reach behind the engine, passenger side. right below the fire wall) but didn't fix it. I pulled out the IAC and cleaned a little inside where its mounted and noticed an improved difference. I replaced the IAC with oem and it fixed the stalling. still has a small idle issue still

Before I read this I had already kind of just jumped into replacing the CSsensor, was a little bit of a pain to find at first, but then managed to locate it, your info would have helped if I saw it sooner.. I'll know if the sensor fixed the stalling by morning when it's completely cooled down.

As for the IAC, I've yet to do anything with it.. I've heard from other dodge owners thought that they've had that issue and it fixed it when they cleaned it up (minus replacing) but may end up looking into that if it doesn't have better symptoms by morning. I'll definitely keep you all updated and hopefully soon enough we all will have our issues fixed, haha.

Enjoy the rest of your night

If you clean up the IAC and it helps it replace it with a MOPAR part. Sensors on these trucks are crap from auto parts stores

Figured I'd check back in now that I've given it a few days of testing, I replaced the crankshaft sensor as I mentioned a few days ago, and so far the occurring issue with it sitting for 6 hours then stalling after words has been supposedly cured. So it hasn't stalled since I swapped out the sensor. Now all there is, is to figure out what my power loss issue is, I'm not sure if it's still misfiring haven't felt it recently, but there is still a major loss of power especially when traveling up-hill.

I made sure to snap a video of it and see what it was doing yesterday, I was going up hill roughly 50 or so and gave it some decent throttle from where I was, when it does get the power it needs such as this situation it hits about 55 and the CEL comes on flashing for a bit, then seizes and goes off after about 30-60secs of flashing sometimes shorter. I figured maybe if somebody else has had this issue they could relate.

Bump^
Don't want to damage anything by continuing to get this CEL issue.
