rough riding

[cevends]

We are dealing with a 97 2.4 twin cam ga . Car has rough idle and runs sluggish at times .Last couple of days it has gotten worse .we have replaced plugs with no improvements ran propane through air ducts and it smooths it out just a little.We then discovered oil in the throttle. So i suspect this is a ventilation problem and i was wondering if these cars come with a pcv if not how does the ventilation work on these cars.If anyone could help with this problem please email with a solution Thanks cevends@aol.c

I'm having similar problems with my car also. Does your check engine light come on?

Could have a vaccuum leak somewhere or a dead sensor.

engine light comes on and off as far as vacuum goes it kinda comes and goes that is why i was wondering about the crank case ventilation
