Idles great...all 4 cyclinders are firing...shift from neutral into gear...engine shuts off

ITS DRY, CHECK LEVELS FIRST, NOT GUESSING
THE users guide covers how . low,<<,x<<<<high
hot engine, in park,idle, must be between the 2 marks
next if ok, is the shift linkage total failures. pure mech.

First thing check for engine control module fault codes, if you have a lean running code then you have a vacuum leak on the engine, this allows air to bypass the idle speed control system and raises the idle up. Another issue is a sticking Idle speed control air bypass valve, but that is not common and vacuum leaks are.

IDLE Sentsor

Put some Sea Foam in with your next gas fill up..helped my 03 Stratus (147,000) runs great

Well lift the car up and put it on drive wile you can hear what the knock is. See if is your engine or the transmission. And if ok check your spark plugs make sure you getting fire to them

I need year model to be precise? But here are the basic tools and troubleshooting steps. TOOL (1) a black marker.(2) a tape measure (3) a second person. TROUBLESHOOTING STEPS(1) the force need water so put it in the lake or install water hose.(2) do not start engine yet. remove engine cover and find shift cable by shifting remote control. once you find were the shift cable connects to the shift linkage. learn which way is forward and reverse. is it push or pull by the cable. remove the cable.(3) now the shift mechanism is removed from the boat controls. this test will require you shifting the shift linkage by hand so stay clear of the flywheel and all moving parts. (4) start engine. at idle speed and you in a safe location near the shift linkage shift engine into forward gear by the shift linkage. be aware how far you need to move the linkage before it shifts into forward. Mark that location with the maker somewhere you can see.(5) shift the linkage back to neutral. mark location were neutral begins. you will fill it click out of the forward gear.(6)now shift into reverse gear marking that location.(7) shift it to neutral making that location as you fill it leave the gear(8) shut off engine turn off water or take it out of lake (9) look at you marks and measure the distance between neutral and forward. the measure the distance between neutral and reverse(9) the second person needs to be in the boat to work the remote control. you need to be at the engine with the tape measure. person #2 needs to make sure remote control is in neutral. you need to measure the remote control cable end so you get a measurment with it in neutral. make a note of the neutral lenght.(10) person #2 shift remote control into forward gear. you measure cable end for distance traveled to go to forward.(11) make the measurement for reverse same way.(12) this is how you find out if you clutch dog is to wore out to stay in gear by the travel of the shift linkage compared to the travel of the shift cable. There are adjustments but they only go so far. that means you will have to sacrifice one gear for the other to make up for the distance of travel.

Your transmission torque converter lock up clutch is not unlocking, that kills the engine and is the cause of the OD light flashing.

shift linkage needs adjusting,,could be bent, easy fix, located along firewall to fram beneath the column, ask your son wut he ran over and didnt tell u about... hope i could help...:)

What engine? Rear wheel drive ?Sounds like shift linkage or cable out of adjustment slightly. Have a look at where cable or rod attaches to transmission for adjustment. If not sure of what your looking for get back to me with info.
