I just bought this 95 neon for $400, IT dies every 20 or thirty min on the highway no warning at all.
I have replaced my, coil, alt and power steering belt, timing belt, coil, coolant temperature sensor, throttle body, tps, aic, and pcm. Now i get code 51&11. what do i do now, and it still dies. sometimes while just idleing, othrs while driving down the highway...

 

might be the crankshaft position sensor

 

did crankshaft sensor cleand batterie posts put thos little fuzzy red and green things on with even new battery clamps. crankshaft sensor, still died. but to day I put on a new set of spark plugs and wires, and the CEL is not on yet and she seems to drive better I hope so I am like ready to pull my hair out dodge dealer didnt know either...

 

meant crankshaft pigtail harness on one of those

 

its called three handfull of sh*t in my gas tank due to the rusted fuel filer neck... new tank and new filler neck and fuel pump and shes running...

 

that will do it
