2003 Caravan, occasional stalling and rough riding
#22
Two problems?
I got the cat converter changed out (ouch!) and two days later she's up to her old ways.. low speed stalling, typically when it's first put into gear.. also some hard shifting... I had suggested to the mechanic to clean out the throttle body and iac again and he did that. Now, I just bought some more seafoam, and was thinking of dumping some in the tank? Any other thoughts?? Any suggestions are appreciated!!

A few days later and it's back to it's old tricks.. it was doing great.. now back to hard shifts/ stalling after starting, and also stalled while turning at a corner!! Completely cut out while going around the corner. It also has an erratic idle at times.. So frustrating!! Any other ideas??

The rough running for the past 2 years has likely been sending raw gas into the cat, which eventually will destroy it. So if the cat needs to be replaced, you're looking at a fairly hefty repair bill - probably around 1K, depending what the actual cause of the hesitation is. You need to find a good shop which is capable of diagnosing the problem, without hanging on a bunch of expensive parts. I would ask them to first check to see if the wiring harness is melted - a well known culprit on these vans.

tpf, I think you should read this post. https://dodgeforum.com/forum/2550634-post9.html This might explain why replacing the crankshaft position sensor fixed the problem for a while but it went bad again.

Phil Ritchie I will let my mechanic know that thread/suggestion!! Thank you for linking it. Last week I had the problem again, that time he changed some temperature thing (not the theramostat) that was related to the computer. Apparently it was not recognizing the car was warming up,so it kept sending in the gas like the car was still cold. However, it was good for a week.. and now the idle was funny as well as the shifting last night. This car-- is TORTURING me!
