Hi Guys I've been a long time stalker on here & found a lot of good info shared by you guys & would like to thank the guys who take the time to share their knowledge. So here is my problem & its doing my head in.....
Last year around the same time I fitted a snorkel & moved closer to work (5 min trip) my car has been getting very poor fuel economy at 16-18L/100Kms,(same as what I used to get when it was standard car towing a Jayco camper)prior to this it used to get 12-14L/100kms. Even worse if I tow a empty box trailer??. I live in the Hunter Valley & did a trip to Surfers recently for a family holiday & the fuel economy didn't change at all.
I'm hoping that there is a sensor/part that fails that can cause this & a scan tool wont pick it up?
The Stuff I have done to my car to try and fix it are fit new genuine plugs/filters, replaced the MAF sensor with a new unit (dropped fuel economy back to high 15-16L/100kms. I Have a scan gauge 2 & the thermostat(only non genuine part - Dayco) opens at 81.C & car sits around 84-87.C once driven for a while.
The only issue & fault code I've had with the car was a slight misfire on #3cylinder around the same time I fitted the snorkel then I fitted the new genuine plugs & haven't had it since. The car is very fuely on cold start up & had a lot of black crap on the end of the tail pipe. It idles fine & drives smooth under all driving conditions. The next thing I'm going to do is put an Autometer Air fuel meter in each side of the exhaust to double check mixtures & confirm its running rich & maybe track down a problem sensor?
The stuff/mods I've done to car
rear cat delete 2.5" system (only put two tanks of fuel in it & it hasn't made a difference),3" MR lift, Diff drop, bash plate, 32" A/T tyres, Prado 3.9 diff gears, canopy, bulbar/side steps/ rear bar drawers, TJM snorkel. I know the car is heavy but before I fitted the snorkel/moved closer to work I used to get 12-14L/100Kms out of it. Thanks in advance for any advice you guys can give me.
Matt.
