Did you torque everything to spec? I'm wondering if there was a bit of dirt or grease on the spline of the crankshaft or in the pulley that needed to be cleaned off. I would have sprayed everything with brake cleaner before reassembly.Thank you SO much for this post. I was able to replace the timing belt on my 2009 Dodge Grand Caravan with help from this post.
When I was done, I noticed the idle was a little rough (it was very smooth before). I took it all apart and it looked like the timing belt was off by a tooth so I re-positioned it. All three marks were TDC. However, the idle is still a little rough!
The crankshaft pulley kinda looks like it's wobbling, but I don't know how it looked before. I did hit it with a rubber mallet to get it on the snout because I couldn't find a installer tool or bolt long enough to reach the threads. Here's a video of the wobble:
The EGR and spark plugs are all relatively new. I replaced the air filter, PCV valve, and cleaned the throttle body. I've looked for vacuum leaks with brake cleaner fluid, but didn't find any.
Any ideas? I don't know what to check next.
