Question about Jaguar XJ8

2 Answers

1999 JAGUAR XJ8L Got a problem, was driving normal under heavy rain, then going up the hill an a very steep hill, when I reached the top of the hill the engine started to shake, made it home like that, engine under restricted performance,the the naxt day the engine just died, and did not want to start anymore, but if I press the gas all the way in, it started but as soon as I let the gas go, the motor dies, then it did not want to start at all. car gave codes P0174 ,P0300, P0301 ,P1313, P1642, P1111, I checked the spark plugs and found out that they were wet with engine oil, somehow engine oil went thru and the top of the spark plugs were wet, incluiding the plugs cover, took the spark plugs off and the bottom ,where the spark comes out was dry no oil at all, but was carbonized, all black, cleaned all the oil ,replaced spark plugs and put everything back and car does not start, checked the spark out of one plug, and it gave a very little spark, not strong enough to fire the engine up,any ideas?? Thank you

    Did that but car won'start, could it be the crankshaft sensor the cause of the no spark situation?

    Thank you.

P1642 is a possible PCM failure

Oil on top of the plugs may of stressed the computer.

All the other codes point to a misfire issue.

The valve covers gaskets should be replaced to stop this condition and the plugs and the boots should be replaced. .

Then clear all codes and try to restart. If the P1642 is still there then your going to have to use a shop repair this since your going to need the new computer programmed.

    You replaced the plugs and boots. Do you have a no start code after you cleared the codes.



    Whats throwing me here is you have a CAN code. Anything is possible on why it wont start now. If you have no spark then it can be a coil, crank sensor, ignition module or PCM issue.



    Also check all your fuses for maybe a popped ignition one or PCM.

P0174 system too lean bank 2, p0300 random misfire, p0301 cylinder 1 misfire, p1313 misfire rate catalyst damage fault bank 1, p1642 fuel pump monitor circuit high input, p1111 intake air temp sensor circuit intermittent high voltage. thats alot of codes all at once. did this vehicle have any codes prior to this? the answer is quite important. if all was good.....replace the ecu. these things just dont throw that many codes, so erratic, all at once.

    if you have little spark then at least youre getting a signal. try replacing the plugs with bosch or champion(i prefer bosch) and then see what kind of spark you have. these do have tendency to leak around the rocker cover gaskets and then would cause the boots on the plugs to swell and leak to ground. all those codes at once are a little too much though.

Jaguar 1999 XJ8L battery won't start unless I


This problem could be a number of things. Let's start buy checking for light bulbs that are not going out when car is shut off, such as under hood lid, under trunk lid, inside of car that are hard to see, such as lights that usually stay on till you leave car but normally go of after a few seconds. You can tell buy waiting a while, they will be hot to touch. If this is so this is your problem.
Next check alternator, get an ohm meter, start car, set ohm meter to about 20 volts, and with car running put ohm meter cables red to positive of battery and black to negative of battery. This test should let you know if alternator is working and good if reading is between 13- 14.50 volts, if you do your alternator is good,if not alternator is problem.
Next check the battery with ohm meter. With ohm meter set the same way to 20 volts, and car off , put red lead to positive post and black lead to negative post . Your reading should be 12-12.50 volts. If reading is low 9-10 volts then the final test would be a load test. You may have to go to your mechanic, or a battery dealer for this one because not everyone has a load tester. This test will tell you if you need a new battery. They will know right away. Your problem could be a bad battery. All the above tests are for DIY. If you are not able to perform these tests yourself then go to a battery dealer they will do tests for you. GOOD LUCK.

I wanna use my 4 wheel drive but I don't know which one to use. I have a 2006 gmc envoy


Depends on what you'd like to use the 4wd for. 4HI would be for faster speeds, or when you need to go faster than say 20mph. AWD would be for light snow on the highway or heavy rains and so on at highway speeds. 4Low would be for going really slow. I hope I understood your question, and weren't asking which knob to turn. Make sense?

While driving along mostly up hills and or pulling my 2002 dodge ram 1500 5 speed tends to loose power. What could be the cause of that?


All vehicles will lose a certain amount of power when going up hill or towing depending on how steep the hill or how heavy the load. Do you shift down when needed.

95 Landcruiser Turbo warning light comes on under heavy load


If you are "lugging" the engine, you will get increased exhaust temperature (EGT), this will trigger your "turbo" light(not a good thing), ideally you should have an aftermarket "pyrometer" fitted to your car, this will show you the optimum revs etc you should be using in any given circumstance.Or revise your driving technique, ie change down gears earlier.
The turbo should be idled down after long trips or heavy towing, this allows the oil temps to stabilise and turbine speeds to stabilise, thus idle for 2-5 minutes.
