Car Died on Highway Help.
 

Was driving on the highway home yesterday and car suddenly dropped to 3k rpms. Pulled into the emergency lane and the car stopped accelerating, once i came to a stop the car died. Wouldnt start up again for an hr and once it did the engine light came on and it died again doing the same thing. I have a 04 MT w/ 56k miles. Thanks.

99% chance of engine replacement. when is the last time you had new coils and spark plugs?

You need Gas? :dunno:

lol, nah i had gas in it at the time this happened.

i dont recall the last time i changed my coils, but the plugs probably need a replacement. i believe it's been near/over 10k miles on the current ones.

what code is the engine throwing?

wasn't able to get it to autozone since it died again otw there :(

is there a device i can buy that can pick the code up so i can tell yall?

spark plugs or coils?

Check for loose battery connections too.
Always nice to rule-out the simple stuff first.

check your battery terminals .....spark plugs....and coils....might be time for a change....same thing happened with me...but my problem was the battery terminals...im at 54k miles with my 04...

^ 54,890 here

alright going to pick up some terminals and order some plugs to see if that's what it is first. then ill go from there. ill keep yall posted, thanks for the help.

Coils

Autozone will loan you the code reader for a deposit I think, well mine does. Give it a try.

get the car off the highway before it gets towed. At the very least INFORM the police who have jurisdiction that you are working to get it off there

Sounds like you went into limp mode.

Perhaps Vapor lock? Open up gas tank cap. (Still need to reset ECU)

Are you sure your not out of gas? If you are at 1/4 tank and do a radical turn you can cause fuel starvation and go into limp mode.

Anyhow, check the battery. Reset the ECU.

The codes will clear and let you drive the car.

No need to replace terminals/cables unless they are corroded.

Car will not come to a stop if you have bad plugs.

car's been at my house since the event happened. had it towed asap, thanks AAA :D

well when i went to go check the battery it had a lot of gunk on it near the terminal, going to autozone today to get the battery checked to see if it's still good, that might need a replacement also. my tank was at 1/4 at the time this happened so ill pick up some gas as well. ill let yall know how it goes, thanks again for the responses.

okay here's an update, so went down to autozone to get the battery checked and it came back bad. so i purchased a new battery and terminals. installed both and the car still doesnt start. could the engine possibly be flooded due to trying to start it when the incident happened?

atm its currently hooked up to another power source while i deflood it, took about an hr last time i had to deflood.

hmm, well still no dice on the car starting. ordered new plugs/coils. going to remove plugs tomorrow to clean em and let em dry.

any other suggestions while i wait for these parts to arrive?

You might want to take it to the dealer.

Your issue sounds far more complex than a simple battery, alternator, or even coils. Have you had the MSP16 flash performed on your car per the TSB? Do you premix? What gas were you running in the car?

It sounds to me like you're losing compression (hard start or no start) and you may very well be dealing with catastrophic damage. Only the dealer will be able to tell you that.

The good thing is that all owners have had their engine core warranty extended to 8 years / 100,000 miles. So your engine is at least covered! :)

i run only premium, as far as the msp16 flash im not certain and i dont premix.

Check the fuel pump. It's not uncommon they die at ~60k miles (of course after plugs, coils, and wires)

yeah that was my next move after the coils/plugs. anyone got a site where they sell oem wires? ive checked mazmart and the other sites people go to on here but no dice.
