My granddaughter has a 1992 Saturn with a 1.9 liter engine, and 115,000 miles. When you start it it idles rough and bellows out enough black smoke to leave a mark in my driveway. It emits black smoke when driving also, and really stumbles when taking off from a stop. It really uses up the gas. I checked the TPS and got.5 volts throttle closed and approx. 5 volts with WOT. There are no trouble codes in memory. It has new spark plugs, and air filter. Hoses and everything seem to be in order. Is it possible the fuel injector could be partially stuck open. I would appreciate any input.
have the same problem?
