When was the last time you did a tune up? throttle body cleaning. pcv. Start simple.

 

Any codes? Are you losing water?

 

i keep it pretty tuned up most of the time and i always change the oil on time i clean my air filter about once every two weeks and run engine cleaner through it pretty often. and i only had one code that was an air flow code about something i dont exactly remember but i changed the part out but the code still shows up.

 

Well if you changed the part and you still have the code you either didnt reset your PCM or havent Fixed the problem.
Do the Key Trick and find out the code, Let us know what it is.
Cleaning You Throttle Body Like P38251 said is a good start and it very simple.
You also never answered my question if it is losing water????? This could be a problem.

 

no im not losing any water and i just checked for codes and now i dont even have a check engine light but i still have the problem should i just start with new plugs?

 

Yes start simple
