Re: 91 civic stalls, decrease in mpg

I would start by replacing the oxygen sensor and performing a tune up.
Before you replace your o2 sensor, I recommend that you get a bottle of
SeaFoam Engine Cleaner. This product can be found at your local Napa
Auto Parts store or Carquest. Start off by removing your air intake
rubber tubing off from the throttle body assembly. Then open up the
bottle of seafoam engine cleaner and pour half of the contents into a
spray bottle. Mix the solution with 50 percent water and 50 percent
seafoam. Be sure to shake it very well. Now, begin by spraying the mist
into the throttle body inlet while manually keeping the engine's rpm
above 2500. You will notice that your exhaust pipe will be emitting
some white smoke. This is perfectly normal because the solution is
cleaning the internals of your engine and decarbonizing all of the
baked on carbon deposits. After you finish the bottle turn the engine
off and let it sit for 15 minutes. Go ahead now and take the car out
for a ride on the freeway and apply heavy throttle to remove all the
excess carbon. Next replace all 4 spark plugs and make sure to gap them
to 0.44 in. Replace your engine oil and filter along with a brand new
o2 sensor. If you perform all these steps correctly, you should notice
a difference immediately. I hope this helps.
