tonycj 0 Posted January 22, 2008 Seems to me that i am constantly filling up my CJ with fuel (1360cc engine), i can get about 250 miles out of my tank, which i think isnt a lot. Can anyone give me any idea if this is fine or not? Also when i am running around in the car it seems to cut out every now and again, only for a fraction of a second but its realy annoying, i think it may be fueling but im not sure, ive changed the plugs, leads, dizzy cap and rotor arm so i think the electrical side of thinks should be OK. Any ideas welcomed, Tony. Share this post Link to post Share on other sites
kate205gti 4 Posted January 22, 2008 does it smell of petrol?? mine ran way too rich! think it still does (davew got it now! ) Share this post Link to post Share on other sites
Sandy 191 Posted January 22, 2008 The 1.4s are usually good for around 40mpg. Less than that and something's likely wrong. Share this post Link to post Share on other sites
GazRallye 0 Posted January 23, 2008 I got 37 mpg with combined driving over 270 miles and it does over 300 miles on a tank (not sure if CJ tank is same as XS) Check the fuel lines under the car and inside the 'bay around the pump and filter Share this post Link to post Share on other sites
RossD 44 Posted January 23, 2008 Yep, my old 1.4 gave me about 40 - 42mpg. The CJ may give slightly less as its a bit heavier. Share this post Link to post Share on other sites
Jrod 7 Posted January 23, 2008 I get about 30. Don't think anythings wrong with the car, just my heavy foot. Share this post Link to post Share on other sites
Rippthrough 98 Posted January 23, 2008 I got 15mpg over christmas, but a change of fuel side parts and I was back up to ~35mpg - which is about normal for it. After sorting the new head out last week I actually seem to be doing better on fuel even with another 20bhp Share this post Link to post Share on other sites

DaveW 6 Posted January 27, 2008 Oh its a spi engine? could need a new fuel filter then. Share this post Link to post Share on other sites
Rippthrough 98 Posted January 27, 2008 Lambda sensor and the throttle position sensor are both killers for the fuel consumption on the SPI if knackered/incorrectly adjusted. Share this post Link to post Share on other sites
Last Legend 0 Posted January 27, 2008 I would check out the fuel pump (access to it under the rear seat) might also be worth having it rolling roaded and see what its set up like. Do you know where it was MOT'd last?A quick phone call will see what the emmissions were like at the time. Share this post Link to post Share on other sites
