Hellppppp gas problem? Newby

95'YJ and i have a question. this is my first stick ive ever had. and i can drive it pretty well. my question is i am getting BADDDDDDDDD gas milage. its a 4banger. and chould this be because i am shifting to high of an RPM? i have the problem of when im on a hill and then i need to release the clutch. and the the gas. 40% of the time i stall. i live in the north georiga moutian area. its like that every where. and this is also my first jeep. i was driving all day today. and i noticed that its not verry fast. it takes a long time for it to accelerate. are all the jeeps like mine like this? im trying to debate if its somthing im doing or of its just the nature of the truck. and i also have a mild exhaust leak. chould this cause the bad gas milage? it tends to backfire every time i let off the gas.

Just take it easy.
Go slow with it. There's a static poin with the clutch and gas which keeps you stable on a steep incline. Just take your time and learn the ins and outs of the clutch.
Bad gas mileage can be due to: air pressure, fuel filter, air filter. Many things. Just do some research

Make Sure Everyone is Dead within hearing and sight range. Only then, you can say any area is cleared.

i average 20mpg for my stock 95 YJ with the inline6 and about 110K on it

Proper maintenance is KEY for good gas milage, o2 sensors, kat converter not plugged up, etc...

I had very poor performance for a week especially at high speeds until I realized it was my kat converter, serviced it, and she accels like a dream. Just remember its a jeep, so it is not fast like your previous cars most likely. You should be able to do 0-30 at a reasonable tempo.

i have a 95 yj 4 banger and slow acceleration and slow over all speed is just the nature of a 4 banger. you probably already know this, but to help from stalling on a hill if you keep your foot on the brake and slowly release the clutch when you feel it start to grab then release the brake. hope this helps sorry if it is confusing.

Think about changing out your fuel filter Anthony. And, maybe flush out the fuel tank if you can.

Until then, run full tanks of gas. There's some nasty sludge down in your gas tank at the bottom.

I've got a 94' 4.0 with a Manual, getting about 19.5 MPG; driving like I'm running from the cops!!! I use Sea Foam about every 3rd oil change in the tank, but I ran it through the top end of the intake when i first got the Jeep 2 years ago (this is the 3rd Wrangler I've had) & it will make a difference in the performance. It also don't hurt to put some on a rag & wipe out your throttle body, believe it or not you will have some carbon build up in the butterfly & surrounding areas. If you can swap out your air filter for a K&N, it will help with the flow of things through the engine. I love my "Heep", as my 3 yr old says. It's the only vehicle I can count on all the time to get me where i want to go, any time, any place. They would have named it "Marine" but that name was already taken!!! Like Razorus mentioned, a tune up will help too.


'94 YJ 4.0 litre I-6 Mated to a 5 spd, shifted with a Guinness Tap handle; Ford 8.8" rear end sporting LSD w/ discs & 3.73 gears, 5 1/4" of altitude riding 33 x 12.50 15 GoodYear Wrangler DuraTrac's.

Everything else is O-ridge-in-AL!!!!
