usually can trace problems with the amount of miles on the car...

 

144,500 miles - Thanks will approach the problem from this angle.

 

I am wondering if perhaps not giving my Camry enough time to warm up and hopping on the highway fairly quickly caused the engine to shudder and for the "check" warning light to also come on.

Was it a misfire?

 

Thanks for commenting. I don't think so, if I understand what a misfire is. There was no popping sound. It was like a tremor or accelerating vibration.

 

has anyone had similar issues or any thoughts on what this is or did I nail it with the cold?

Something similar. During the winter, upon a cold start, first thing in the morning, my engine would always misfire.

Upon a quick visual inspection, nothing seemed out of the ordinary, until I plugged in an OBD2 scanner. Cylinder 3 mostly, would misfire for a second or two and not misfire afterwards, throughout the day.

The spark plugs had less than 15,000 miles on them and the fuel injectors were fairly new, so I suspected a bad ignition coil.

I changed all four ignition coils and the misfires disappeared.

 

Thanks for commenting. Something to think about.

 

@Carbor if there was a check engine light, it means there was a trouble code stored, get a scan tool or have it scanned to find out what code it was.
The code or codes will provide you with information on what was causing your problem instead of guess what it might be!

 

Thanks. I will have to get this app. I was looking at something online regarding OBD and torque.

 

Welcome to the site Carbor.

If this is a single instance, hard to tell. Have it scanned for any saved codes and post those up.

 

Thank you. At present I don't have a device to perform some of the suggestions, but this is definitely motivating me to upgrade.

 

if you dont let the car warm up the computer will not regulate air and fuel thats why it sounds rough when you first start it and over time this will cause damage to the motor

 

You're right and today particularly I am guilty of that. I will be more mindful of that from this point on. Thank you.

 

after trying wireless I I prefer wired.. but as long as it works..

 

after trying wireless I prefer wired.. but as long as it works.. as far as shudder, a spark plug tells a story, what do they say?

 

With modern engines and modern multi-vis oils, the engine probably will start Okay under cold conditions and you are not likely to damage it. But you cannot avoid the fact that gasoline vaporizes much less well when it is cold, and this will amplify the effects of minor problems with tuning, ignition, and and fuel distribution.

 

That's what I thought, but I am going to make more time to warm my baby up and the incident so far hasn't happened again.

 

"coldest day of the season, it was 25F"
"condensation all over the windows"

When the weather gets cold, did you have a empty gas tank?
When Temp Drops... you get condensation in the gas tank. The moist air condenses on the metal walls, when gas sloshes or you fill up the tank, the new moisture settles to the bottom of the tank and get sucks up to the injectors. Get enough water in there it will not run at all. Add a can of dry gas and baby your car for a while. Winter temps I never let my tank go below 1/2 full. IF weather says temps to drop, I fill my tank up before.

You can get water from the gas station pump for similar reasons....
I keep a can of dry gas in my trunk just in case.... can keep you from being stranded
Try not to use the dry gas it is mostly alcohol and is hard on rubber parts in your system.

I have mixed feelings about the 10% ethanol content of regular gasoline, since I don't believe that it ultimately saves energy or reduces emissions. But it will absorb any moisture in the fuel system which makes the use of any alcohol-based additives redundant, such as dry gas.

 

144,000 mlles it is clogged injectors. It may be a P0171 code (lean bank) or P0300x indicating a specific cylinder misfire. Step One: Add Techron Injector Cleaner before going crazy. You can see it with the scan tool with live data but you'll feel it get better after a while. The Long term fuel trim will be higher than 10% at hot idle. After the techron the LTFTR will start varying between plus and minus 10 (normal). May take several treatments. Quicker and cheaper than paying a shop to hook up their machines and works as well as replacing them. Injectors last like 300,000 miles. P035x (P0351 is cylinder 1, etc.) would be that cylinders primary/secondary circuit misfire. Replacing plugs is advised at 90,000 but not likely your problem today.
