Ok soo the past week ive been having this horrible stumble when accelerating fast but yet i have it in low rpms...i noticed my car isnt very fast anymore...it tends to stumble more when its been runnin for more then a few minutes?? i check the plugs wires egr valve fuel injectors ...what could it be?? thanx for any ideas...

 

your car could need a tune up. how many miles on it?
optispark?
jesse

 

150,000 miles on it today....havent ever changed the opti, i have a leak soo there has some oil leaks on it.....could it be bad/??

 

that could very well be it

 

i would venture to say your opti is trash

I had a leaky water pump and it KILLED my opti.. the hotter my car got the worse the stumble
