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. For all your Honda and Acura needs, check out http://www.trackspeedracing.com.
