chrysler 300 touring limited edition i have a problem?

[MELISSA S]

If i do not warm my car up every morn. cold or hot weather it start to vibrate about 70 mph and the rpms go really high while its doing this and then the check engine light pops on for a min and goes off and then it runs fine. Is it spark plugs, fuel, injector or worse case transmission?

Don't know right off not knowing the condition of the engine. But warming a car/truck up in the morning doesn't help the engine any and is expensive. An engine dose better driving to warm up than letting it set and idling. An engine idling (and I'm not making this up) Wears more than when driving even in cold weather! The trans.won't shift into overdrive until the engine temp. reaches a certain degrease. This also helps the engine too warm up.

thats not a common problem, you should have it scanned somewhere. depending on the year, it may still be under warranty

sounds different. sounds like it should be electrical. could be alot of things. you should take it to a dealer. you will still at least have you 7/70 powertrain warranty if not more, so hopefully woudn't be more than $100 deductable.

Well i think this is a good suggestion for you as your Chrysler stills falls within the warranty you need to take this to your dealers and explain them this issue they have to get this rectified for your and they will check it properly and if any of the parts are worn out they will get it replaced for you.
