I'd be more inclined to think a shock like that would damage the main board in the computer long before the throttle body. The only way to test for cracks with it on the vehicle is to use a smoke machine.

 

 

 

 

 

Seems to me, if the long list of parts (sensors) fixed the backfiring/rough idle, but the pot hole jolt caused it to start running same as before, those replacement sensors is where you might begin checking...
troubleshootmyvehicle.com in the Chrysler section gives some good easy to understand walk thru's for testing some of the sensors
It may be helpful if you could list which sensors/parts were replaced and what were the brand of the new ones... aftermarket ones aren't very popular , you'll see as you read through related threads in the forums.

 

 

Good idea. The other arguably more important one is the crank sensor. My original was a Mopar but when it began failing the engine would die while letting off the gas pedal coming to a stop. I got good at the two feet working the brake and gas, If I missed the timing on the stop I could go to neutral and restart right away and two foot it till it got moving along fast enough again.Drove it that way for well over a year, it happened intermittent but fairly frequent.
Then found the forums here and the answer to why my engine was dying on me at stops, so switch out the cks with a bwd brand sensor and after a few months it failed but the symptoms were not the same... It would drive a handful of miles then suddenly run rough and engine would cut out at low speed, maybe 35-45 mph then simply die and not restart for 15-30 minutes. then would start and repeat the same thing, drive a few, cut out and die.
Replaced cks with an autozone brand and has run well for about 2 years so far, but next one will be a Mopar one, have it ready for when that day comes.
