Question about 1998 Jaguar XJ8L

Engine starts but cuts out as it settles to idle revs

I have owned my 1998 jag xj8 from brand new and until last week it has run perfectly, the engine starts fine and will keep running if the revs are kept above 2k. but as soon as i ease off the throttle the revs die away complely and being automatic its almost impossible to drive like this as when engaging drive the car either stalls or screeches through the garage door. any ideas ?????

    thanks for your suggestions, given the throttle body etc a good clean up and had a good look round. no visible damage and butterfly operates smoothly. but still no joy. no warning lights are lit up on the dash, nothing appears out of place, so beginning to think there must be a prob deeper inside the engine. maybe an ecu fault ??

    Thanks for replying  tom if there had been an  ecu fault there would be a faul tcode  check the fuel pressure to the engine  there rail e is a take of valve, up on the rail D

    Hi tom this sounds like throttle body one thing to check when you look down the throttle body is  the butterfly working when you remove the intake. and get someone to press the throttle with the ING on   let me know D

Obviously, without the vehicle in front of us, we are all guessing here, but it sounds to me like a vacum or air intake leak as well.

High rev at cold (winter cold!) idle


Your toyota technician should know what a "cold starting solenoid" is. It is the little thing that works your throttle until the motor warms up and something else takes over. I'd suggest going to another technician.

Pathfinder "cuts out" at 2,300 rpm


Replace your MAF, its a little pricey around $280.00 or so but this will clear the code but make sure you have the ECM reprogrammed to perform a "learning" sequence since sometimes the code will not clear even though the vehicle will run like new. This reprogramming will most likely have to be a dealer performed procedure.

1988 Mercedes Benz 300E 3.0L Gasoline F.I. ''Sputtering at Idle


ok..you must have more than one car???? you don't drive the 300 atall im guessing. #1 start car drive up the road and \back to your house. #2 let it idle till problem starts. #3 once it does start with the problem keep it alive with the gas pedal. #4 once your have it safely from dying in higher rpms "rev it" like a kid would, you know like if you were gonna race some one lol. be careful not to over rev or damage engine. you should do this for five minutes no longer than that. #5 let it idle for another 5 minutes. #6 repeat every day until problem with idling decipates. it took mine 3 300e like 3 days of this. if your not going to drive the car once you get the problem out of the way. turn the car on everyday and let it idle for 5 minutes atleast and take it for a short drive once a week. they get lonelly you know lol. later on you can just turn the car on every 2 -3 days and let it idle but still take it on a short drive atleast once a week

You haven't changed everything...map sensor controls spark and fuel mixture as does the throttle position sensor, also check the idle control valve...Don't just buy stuff...do testing first.

Intermittne revs when car starts until it warms up.


Sounds like you have an air leak from one of the vacuum lines. Does the engine idle normally when at normal running temperature?

Take the car to a specialist to check the timing chain tensioners, they are a known issue. I`d advise you to not use (or even start) the car till theyve been ruled out, the engine could be made scrap if the tensioners goes.

If it does need tensioners, get the later metal type ones fitted.
