Chrysler Repair: 99 Chrysler LHS Ignition, 99 chrysler lhs, chrysler lhs

Question
About 5 months ago, my car overheated and died on the road.  About 2 months ago, I decided to get it looked at.  The guy found out that my water pump locked up and caused my timing belt to snap. We found millions of pieces of the timing belt inside melted on the gears, etc.... Replaced the water pump, the tensioner pulley (it was broken and ball bearings were all over the place), and the starter.  The car is put back together as of last wk however we're running into some road blocks.  When the car turns on, the engine shakes and idles very rough. It runs very hesitantly and slow while taking off, but whenever I get on it, it goes as fast as it used to.  Once I stop again, it does the same thing, almost dies.  Check Engine sign indicated a P0352 error "Ignition Coil B" but AutoZone couldn't tell me what this was. Pepboys told me bunch of different things that made sense 50%. When I unplug the ignition coil wires on the right side of the engine, nothing happens to the engine.  It runs same as all wires plugged in, which points me that either all or some of the cylinders are not firing on the right side.

I don't understand how they won't fire when I start the car but then start working properly when I go fast.

Answer
Hi Metahan,
The O352 says the primary circuit of the coil on the number 2 cylinder is faulty. That could either be the coil or the tan/pink wire from it to pin 3 of the ecm. So check that wire for continuity. And if that is ok you might try switching it with another coil and see if the fault code moves to the new position which would prove that coil is bad.
On the idle vs road speed situation, I am wondering whether you might not have damaged a valve in this incident. You didn't say which engine you have but both the 3.2 and 3.5 are
non-free wheeling valve trains which to me sounds like damage can occur if the timing belt brakes while it is in motion. So you might check that out via doing a compression check on the weak bank of cylinders to see if any are low. It is conceivable to me that such a situation could be manifested that way. Alternatively, another possibility is that when the timing belt was put on the timing mark of the cam sprocket did not actually end up in the proper position which might make a big difference at idle but less so at road speed. So remove the upper covers and see how the two sprokets align with one another.
