So I have been having probs with my 05, rough idle, stalling, loss of power. When the engine is cold seems to run ok after I get it started. When the engine is operating temp engine shakes, and when I step down the peddle fully it revs up high but doesnt change gears smoothly makes very loud sound before it changes gears(auto). The temp gage looks normal but its running very hot.

Does this sound like a prob with my engine or the cat? I dont see any CEL on.

 

when was the last time the car was serviced? How many miles on the engine? Any modifications?

 

Bought the car at 30K miles now at 107K miles. I had the SSV valve and spark plugs replaces at around 100K miles

 

what about general maintenance? (plugs/coils. oil change, etc etc)

 

I take it in for oil change regularly around 3k and i had the spark plugs replaced recently not the engine coil though.

 

change your air filter, clean your MAF and eccentric shaft sensors. Test your ignition coils and spark plug wires.
Check your transmission fluid, check your motor mounts for any damage.
Last, inspect your cat converter to see if it glows red after a drive. If not, pull down the front and look inside to visually inspect

 

Do you have any links on how to check the plugs coils and cat. pictures would be nice cuzz im not very tech saavy
