sounds like a dodgy height sensor on passenger side. it could be stuck. look to see if its still connected right. spray some wd40 on it. may work may not.

2006 dont know till i take oil pan off and the front timing cover to see if its the chain as well as the vanos. it could have chucked a plug. its comon on these heads to go soft after running on lpg for a few years. right back to the 2003 l322 with the throttle body problem its been run for 50...

studying my other l322 2003 its engine noise. think its the vanos seals. not the chain guides. its a banging noise?

ok then i cleaned the throttle body out with rubbing alcohol today. took it for a run its much better. revs dont stay up when first starting from cold. runs bit smoother. so ill run it in morning to see how it is. i ordered a new throttle body anyway for 160 new. ill put it with my other parts...

took it to a sure start to a mate. hes a great diagnostician. hes tested it and came up with throttle body problem. so ive found a place that sell new throttle bodies. £160. ill let you know if this is the answer. thanks. and yes i now have chain guide problem on my other 2003 l322. so i will...

bought this because i was told the 4.4 jag engine is best out of them all.up to now it has been.i will get to the bottom of it.

thanks for your time on this and your thoughts are welcome. i will have a look in the morning for a SAI but not seen one on this engine up to now. the 06 plate is the swap over to jag engine. they do have a vacuum valve which i did change as it was the only fault that came up at the beginning.

loads of air freshener trees. everywhere under the seats in the back in the boot in the dash .never knew why when i bought it

gear box is ok had it looked at today. holiday chicken mine does the same as yours does. but it never used to. ill check that SAI pump. it very well could be that. i also think it could be an oxy sensor on the exhaust. but its not come up on the dianostic.

had box serviced a month ago by a good mate of mine. all they do is gear boxes. said it was top class box. ive ordered a air flow sensor so see if that does the trick. live data said little rich on fuel.

TF IID PRO, nothing shows up

LS7 then you would need to up rate the diff,s and axle running gear. were do you stop lol

very very nice. indeed

maybe i havent used a clutch since 1979. i put foot down, the rev,s go up. but i have to wait till car catches up. so fuel goes in but no air i think. i dont think these engines have speed sensors. 4.4 jag 2006

hi again im still stuck.. new symptoms, when driving along at any speed its ok but when you put foot down to go faster!! the revs go up but car delayed action to catch up. even with foot to floor. car takes long time to catch up to the speed you want. would this be the throttle body.

this is just a guess but would the speed senor in the middle console under the hand brake. make the engine eat more petrol because ecu would try t compensate. then the oxygen sensor would do the same so the cycle begins... the only thing is i dont have any loss of power.. it drives just as...

no its still only doing 17 to the gallon. when it used to be over 24. talked to a RR member he thinks it could be oxygen senors not working. i asked why its not come up in a diagnostic. he did remind me that we had cleared all the old and new stuff in june. so he thinks it may not be showing up...

waiting for the wet weather so i can go out. in my RR

valve block maybe blocked..or change the other side height sensor so both front sensors are changed then look at the valve block. the one just after the air cylinder,

i have now cleaned the throttle body very carefully. engine has settled quicker now. need to give it a run. see if the fuel isnt still going down as quick. think thats done the trick.
