I recently changed the plugs to NGK plugs and now I noticed that sometimes when idling it will almost stall and if in gear and stopped it will actually stall. The engine is a 3.3l. Anyone now if the Caravan is picky on plugs? Maybe the MAP sensor? The check engine light is not lit and my OBD II reader shows no codes.

 

I should also mention that I hit this sensor accidently when installing the plugs but moving it around doesn't cause it to stall and I did not hit it hard but did move it.

 

It is getting a lot worse now, it almost stalls at all interactions even when in park or neutral. I disconnected the O2 sensors (both), and the EGR valve, same issue. I also tried a second coil and replaced the plugs, same issue. When I disconnected the EGR valve it seemed to act better for less then 5 minutes but is now really bad. The van is showing the code P1128 now.

 

I thought the EGR on the 3.3 is designed to stay open if the electrics are disconnected. Meaning that, it would flow at idle and cause a stall at low revs. It's been a while since my P0405 code and EGR replacement, maybe the memory is going.

 

That will make it very hard to troubleshoot

 

You can run the car without the MAP sensor. Just unplug it, and see if it runs.

 

I have a 2010 gc with a 3.3 & 17,000 miles is it ready for plugs ??

 

I believe they are rated for around 80,000 miles but I am not 100% sure. Certainly more then 17,000

 

In the '08 owners manual, the spark plugs (type ZFR5LP-13G) are replaced at 102,000 miles / 170000 km or 102 months. Same schedule for the plug wires.

 

I took the van to the shop, the cam sensor is not responding. Unfortunately I have to wait until tomorrow for it to come in so I will see then if that solved the stalling issue.
