I recently purchased a '98 Cruiser and had the following completed: New timing belt, water pump, starter, spark plugs, fluids, etc. I have driven it for six days after all of the work was completed without issue. However, I started it up yesterday morning and noticed it missing at idle and low speeds. After driving if for a bit it seemed to be fine. I decided to run to the store later last night and the miss continued and has gotten worse. Anyone have any ideas of where to start troubleshooting?
