Can't figure out what it can be causing this plz help! My car when first starts up in the morning it starts chugging like its going to die out. The car won't accelerate, I get MSG cruise control not available. It seems like the car looses power B/c break pedal is hard to press. To get car going I have to punch gas pedal down. Engine light also flashing but stops after awhile and just stays on after that. Car runs fine pretty much runs fine after initial start. It seems like getting a little more rough though.
I took car to Auto Zone to have codesj checked. Diagnostic reads all 6cylinders misfire. I think it also reads something like cat system failure. When car is running there is also MSG DSC system fault.
I have had 2 oxygen sensors changed B/c Was getting a code for those and b/c gas was burning to fast but not as much anymore since I changed them. I also changed all spark plugs too. I'm kind of thinking it might be fuel related but idk.
Can someone pt. me in right direction?

 

Welcome to the Forum.
Please take time to visit
New Member Area - Intro a MUST - Jaguar Forums - Jaguar Enthusiasts Forum
and introduce yourself so we can all say 'Hello'.
You need to read the codes now - bluetooth OBD dongle and the 'Torque' app on an android seems reliable.

 

What are the code numbers that Autozone read?

-Check your vacuum lines.
-Check the amperage on the battery, not just the volts.
-Make sure you have the ribbed hose installed between the PCV and Intake
-Clean the throttle body
-Clean the MAF - Replace the MAF
-Change out all 12 gaskets on the intake. 6 below and 6 above the fuel rail below the intake manifold
-Change out the IMT valve gaskets

Reply with the codes and we can pin ot down a little further

 

Hello All! My name is Angelo but u can just call me G-lo. Thank u Steve and Jeeves12. I'll get codes and update u when I find out more.

 

Do u guys think it could be the coils that need replaced? If so would it read all cylinders are bad?

 

If it was the coils there would show up as 1 or 2 being bad, not all of them.

Take the battery in and have the amperage checked. I had 2 batteries that both read 12v, but the amperage less than 25% of the rating of the battery. It caused the same problem. (BTW - These were Duralast from Autozone. I only mention this because you had the codes read at Autozone) I would get this checked out first, so you're not chasing gremlins when everything else is being replaced.

Then post the codes. This will help us point you in the right direction for the problem.

 

Here's some pics to help you out.

 

From G- lo
Ok I got the codes they are as follows


P1313
P1314
P1000

Misfire cylinder 1 P0301
Misfire cylinder 2 P0302
Misfire cylinder 4 P0304
Misfire cylinder 5 P0305
Misfire cylinder 6 P0306

Catalyst eff. Low bank 1 P0420
Catalyst eff. Low bank 2 P0430

Ok thank u ,and let me know if u need anything else.
Those pics also will help thank u!

 

G-Lo,

Sounds like the fuel rail is clogged up or bad. See the attached link.

1 - Run a can of fuel injector cleaner through the engine and see, if it improves.
2 - Check the fuel pressure "about 50 psi" -Thermo
3 - Look (listen) for a vacuum leak
4 - Have the fuel rail cleaned or replaced

All the codes are a result of fuel/air mixture being off. Therefore, 1 coil isn't causing the issue and the chances of all coils going bad are slim.

 

Jeeves12,

Sounds about right, B/C I feel I'm burning a lot more gas than I should still after changing the o2 sensors.
I'll get the fuel rail checked out. Keep u posted

Thanks for info.

 

The other (simple) possibility is a bad tank of petrol or a blocked fuel filter.
The filter is easy to replace and worth doing anyway (unless you've recently done so)
You'll be able to see if the fuel is dirty at the same time - here's a link

Hey been busy sorry took while to reply. Ok we'll I found out the dealer I bought car from never changed spark plugs like he said. The plugs were bad. I took my car to another mechanic and had them changed. It's not bring misfire anymore but my mechanic said I still need 3 o2 sensors changed so I have to do that still. I had 2 recently replaced. I'm also going to change fuel filter. Oh and i also had to replace my PCV hose. it had holes in it. My codes I'am getting now are

P1111, P1603, P0420 and P0430

My jag still has rough start in the morning. The engine shakes. What can still be cause of this ? The mechanic said coils are fine. He also found a small oil leak in rear seal. He said it would cost like $1200 to replace seal. Is there a cheaper way to fix this?

 

G-Lo

P1111 - Generic Code, nothing to worry about
P0420 and P04302 - Catalyic Convertors. I wouldn't worry about these two. With all the issues you've had, it'll take time to clear out the CATs. These 2 codes should go away own their own in time.

As for P01603 see the attached link.
https://www.jaguarforums.com/forum/x...function-2009/

As for the oil leak. The transaxle needs to be removed to drop the oil pan. This is the reason for the $1,200 quote. There is a simple way, but it requires some cutting on a bolt housing of the transaxle. Here's a link
https://www.jaguarforums.com/forum/x...-gasket-85599/

Let us know, if the rough idle goes away with the P01603 "fix"

 

Thank u jeeves12,

I forgot to mention. I'm also getting a gearbox fault msg now sometimes too. It pops up sometimes and goes away. My transmission feels like now its slipping a little in 2nd and 3rd gear perhaps. Does this mean my transmission is going out? So do I need to check the transmission fluid or change and if so how b/c I have been told by the dealer they are sealed for life.

 

Jeeves 12,
Oh ok is the reason for the code P01603 causing me to get the gearbox msg. ?

 

G-Lo - If the "gearbox at fault" or "Cruise not available" message is being shown, the car just won't go. It seems like the transmission is slipping. With that being said, get the other issues fixed first. When the codes and the rough idle goes away the "message" will disappear and the "non-tranny issue" should disappear as well. Hope this makes sense.

If there is NO "cruise not available" message and the tranny "slips", then you have an issue with the transmission.
