ls400boi804 Posted April 22, 2009 Share Posted April 22, 2009 well first let me start by sayin hello to all..well i got a ls400 1991 for 600 dollars and it drives fine for the most part. has 196,000 on it.. Well i was riding one day and it was on e, and the car starts to act up. it cut off, and acts like its being starved of gas... so i put fuel injection cleaner in and put gas in and it was fine... So i thought if i changed the fuel filter it would be a quick fix. but still the same.. IF THERE ANYONE THAT HAS HAD THESE TYPE OF PROBLEMS COULD U PLEASE HELP ME OUT... I Love THIS CAR!!!!!!!!!! MY NEXT STEP IS TUNEUP,FUEL PUMP,FUEL INJECTOR?????????????? ANY INSIGHT WILL HELP A LOT THANX Quote Link to comment Share on other sites More sharing options...
Bali26 Posted April 22, 2009 Share Posted April 22, 2009 Could you be more clear? It was low on gas so it spluttered, you added gas, then it was ok. Now it does it on full gas? Quote Link to comment Share on other sites More sharing options...

Now it does it on full gas? ok it happens now usually when the gas hand is reading between half a tank and 3/4 a tank.. it cuts off , and everytime its starts right back up but rpms struggles to reach 1, with me pushing gas pedal it barely responds, and then once new gas or fuelinjector cleaner is in put in it the problem dissapears for days even weeks at a time what does this sound like to you? any more specifics please ask Quote Link to comment Share on other sites More sharing options...

Generally if the gauge is on E and the engine sputters and acts starved for gas...its because the car has run out of gas. Quote Link to comment Share on other sites More sharing options...
