Question about 1997 Saturn SL
QUESTION: I have a 97 Saturn SL 2 152k mi. I myself, have replaced the ENTIRE fuel system including injectors and plugs and wires. The car still bogs down to the point of stalling upon acceleration from a dead stop.( scary in traffic ).When it stalls, i have to give it full throttle to get it to re-start ( hard start ) and then it blows white smoke from tail pipe and it smells very rich. I have also replaced the head gasket because of oil in coolant and the valve cover gasket because of a minor oil leak. Once the car is running down the road you would think you were in a brand new car( everything is perfect!) One other thing, sense i did all this work the temp. gauge barely registers above the C although the heater works GREAT. Could this be as simple as a ECT sensor , a bad coil, or throttle body. Any ideas would be of great help. I am at wits end and tired of buying parts that dont fix it.Thanks in advance
You need to change your ECTS and it's connector if it has gunk and corrosion in it. Change the ECTS to the brass tipped one and get rid of the plastic tipped one in the car.
Also change your Thermostat which is located inside the lower radiator hose on the engine block. Sounds like your car is running itself rich because it thinks it is cold and flooding itself (hence the full throttle which is a "clear flood mode" and shuts off the injectors while starting).
