Sounds like carbon deposits to me.
Will a 1998 Toyota Camry motor fit in a 1999 Toyota Camry
No, it will not.
May be throttle plate stuck--with engine off try to "free" up with screwdriver
I would check the air filter first. If the filter is clean you need to clean the throttle body.
Yes. Both Toyota and Camry are proper nouns (brand name and model).
That would depend on many things. The year of your Toyota Camry, engine size, and how you drive.
Toyota Camry
I would assume it would be a Toyota Corolla, Toyota Camry, or Honda Civic
I have a 97 Toyota Camry and was told it would be anywhere from $1000 to $1600 depending on whether I wanted top of the line struts or not.
Both cars should have same kind of engine: either 4 cylinder or 6 cylinder.
Look in the owners manual. Ask a dealer or a parts house employee. Look on the AT dip stick.
