Thread: Loss of power continues

Hey guys, hope you can help and love the forum.

Okay down to business. I have a 98 Disco V8 on lpg which runs fine giving me 360 to 380km's highway on 70lt gas tanks. Petrol is the small 40ltr tank I think, but the problem is with the petrol. If I switch over to the petrol it will run fine for about 10 - 15 mins then it wants to stall, or feels like petrol starvation, or starving. If you gently squeeze the throttle (we are talking mm's at a time) it will slowly increase in power, but don't ever ask it to accel hard, sounds like a major flooding. This sometimes happens when you start first thing in the morning (always stop it overnight on petrol) and you get the flooding, or starving sensation.

I've only had the wee beastie for about 4 weeks and not sure if it's the MAF or the petrol pump or something else. The donk has had new leads all round and the coil, to my surprise after reading the threads, is bosch although I don't know if its had the full Bee Utey treatment.

Your thoughts please guys as this is a real pain in the ........................ air intake. Oh speaking of intakes, the engine has a 'pod' air cleaner installed as well.

Find an air cleaner off a 3.5 Disco or 3.9 RRC which connects up to your standard MAF but the air cleaner cylinder is made of steel. Clean the MAF with MAF cleaner spray.

Have you checked the petrol cap isn't holding too much vacuum? Remove when idling and see if it changes the idle.

Check the EFI sensor plug is clean and tightly connected, the sensor itself should read around 300 ohms at normal running temperature.
