    same problem. Bought it recently and got a new fuel filter and starter but still poor gas mileage. Mayhaps a FULL tune up may help?

When i have a full tank of gas my honda civic runs fine when it brakes when it uses gas it stalls when i brake


Hello James, It sounds to me that the gasoline pick up tube has come off of the electric fuel pump. The tube should reach to the bottom of the tank.

I have a 1997 Honda Civic with the vtec engine. I


If the engine calls for a 5w 30 weight motor oil,then stick with it,and use a blend,or full synthetic oil,castrol is the best,and use this fuel treatment,if you want to see a difference in fuel usage ,LUCAS fuel treatment,use it with as less as possible,fuel.It will work better,to clean the fuel system,and the injectors.Make sure the battery is real good,and check the alternator at the battery with engine running,it should read,13.65 volts,to 14.25 volts,with everything on,anything less,is not enough,replace the alternator.If the charging system,battery included,is not up to par,then the alternator works hard all the time trying to charge the battery up to full ,and it never does,because of ,either the battery is not in good shape,or the alternator is charging too little,and when the alternator engages,it pulls down on the engine,therefore using fuel more.

91 civic runs fine but stalls without warning


Could be many, many things, but just off hand I would have your fuel pump checked. Almost any garage should be able to tell if your fuel pressure is where it should be. The problem, of course, is that a failing fuel pump will run all right, and then it won't, and then it will. Eventually it will fail altogether and then your car won't start of run at all.
Hope this helps.

91 honda civic dx. Starts, runs for a few seconds then stalls


Try pounding on the gas tank with a rubber mallet or similar tool. (careful not to dent the tank) Try starting it. If it runs, replace the fuel pump (it's nfg). I've diagnosed numerous fuel pumps this way. Remember the pump needs to be replaced, if you drive it, you don't know when it'll fail for good. Hope this helps. Please post the results.
