Question about 2001 Nissan Maxima
I only get 250 miles per tank from my 2001 Nissan maxima.
I have a high flow intake and cataylic converter in which I thought I would see a change in my gas mileage. I have had a tune up and made sure tire pressure is good.
I noticed this change when the dealer changed the computer system 3 years ago however I have taking it back and they say it's not a problem. Can someone please provide feedback.
CURIOUS IF YOU ARE REFFERING TO THE ECM UPDATE THEY OFFERED FOR FREE ? IT WILL REALLY MAKE YOU WONDER? CHECK YOUR MASS AIRFLOW SENSOR- IF YOU GET A DTC THAT STATES YOUR TOO LEAN TO SYS BANK 1 REPLACE- BE CAREFUL THOUGH THE MAF SENSOR CAN BE EXPENSIVE-ORILEYS SEEM TO BE THE CHEAPEST AND DO NOT BUY THE SENSOR WITH THE HOUSING. 419.00 VS. 180.00 ITS ONE CLIP AND I BELIEVE 2 SCREWS. VERY TRICKY CAR SO BE CAREFULL . ITS A VERY DETAILED PROCESS THAT HAS TO BE FOLLOWED SO IF YA ARENT WILLING TO RISK IT TAKE TO
A DIFFERENT NISSAN DEALERSHIP ASK FOR AN ESTIMATE FOR REPAIRS AND A PRINTOUT OF ALL REPAIRS MADE BY NISSAN- FREE AND VERY GOOD TO HAVE- TRY THESE AS I HAVE AND SEE IF YOU GET ANY RESULTS;
CHECK BELT TENSIONER...
CLEAN FUEL INJECTION SYSTEM.
UPDATE YOUR ECM TO ACCOMODATE NEW INTAKE AND EXHAUST
REPLACE MAF SENSOR-
CHECK EHAUST FLANGE- MOTOR IS KNOWN FOR ITS ABILITY TO PRODUCE EXHAUST MANIFOLD LEAKS- WITH HOOD UP ITS THAT PUTTER SOUND NOT VERY LOUD AT ALL BUT GAS MILAGE IS REDUCED
CLEAN GAS TANK
GET GAS AT ANOTHER STATION- I FOUND THAT IF I SPEND THE EXTRA DOLLAR OR SO PER TANK ON 91-93 OCTANE MY GAS MILAGE PER TANK INCREASES 200 MILES EASY
CAR MANUAL EXPLAINS EVERYTHING SO IF YOU HAVE OWNERS MANUAL READ THRU TROUBLESHOOTING BEFORE SPENDING LOTS OF TIME N MONEY YOU DONT NEED TO . YOU HAVE THE ANSWERS IN THE BOOK . ALLDATA.COM HAS A GREAT MANUAL AVAIL ONLINE ALSO YOU MAY CHECK LOCAL LIBRARY. DO SOME HOMEWORK SAVE SOME MONEY
