First step, clean your MAF, change the air filter. That is what caused it in my 97. Mind you I have the 4l V6, but the engine management is the same. Don't use brake clean, there is MAF cleaner at the parts store, get that and clean it good. Don't use anything that will leave stuff on the MAF such as paper towels, or damage it like a wire brush.
