I've got a2003 jaguar s type 50k miles. It has been doing a jerking or a pulling feeling. Like the tires are being pulled back. Happens at 35 mph and continues to about 50 mph. I took it to shop and they said it needed spark plugs and a pcv hose bcz it was also running rough. The light went off and it was ok for a month then light back on and same tugging/pulling/jerk..not sure what to call it. The light that's on is the orange checkengine one that'll do limp mode according tomanual. It was solid but yesterday was blinking. I am a girl and know nothing about cars but the last repair cost me 550and i just can't afford that again. I hope you all can help.

 

Are you saying they fixed it the first time and now it is doing it again? It would be hard to say what you have going on until you have the OBDII trouble codes read and you post them. If you are in the US go to any AutoZone or Advance Auto they among others will read the codes for free.

 

Welcome to the forum, SadJag. When Gus says go get the codes read, he means report back here with the actual codes. They should be of the form, P####. The auto parts stores will read them for free but will also be only too happy to tell you "what they mean" which may or may not be accurate. Fine, thank them for that good information but make sure you walk away with the actual codes they read. Have them print them for you if you can. Otherwise, just write them down so you can post here, where the info is far more likely to be accurate and model-specific.

IIRC, a flashing MIL (Malfunction Indicator Light) is indicative of "catalyst-damaging misfires,"
not a good sign...

Good luck,

 

The light has several common names. I forget which is the "official" name. It can be known as the Check Engine Light (CEL) or Malfunction Indicator Light (MIL).

If the light is on steady, it's usually not a big deal as long as the engine is running okay. It's telling you to have it checked soon.

If the light is flashing, that means the catalytic converter(s) are overheating, usually due to unburnt fuel in the exhaust. If the light is flashing, do NOT drive the car. If the light was only flashing briefly, the converters may be okay once you correct the root cause of the unburnt fuel in the exhaust. I had this happen to me about a year ago and my converters lived.

As the others have suggested, get the codes read and let us know what they are. Please tell us the actual 5 digit code, not what the reader may say it means.

If there's a place near you that can read the codes, you'd be okay to drive there slowly as long as the light isn't flashing. If you can't make it anywhere without the light flashing, you can pick up an inexpensive OBD II reader usually for under $30.

Please don't be overwhelmed. Get us the codes and I'm sure we can walk you through it.

 

Hi,

First rule here is don't panic.
If you have a laptop I would buy an elm327 from Amazon then download a free copy of this program
https://www.boutiqueobdfacile.com/eo...tware-a64.html it's a French program but it can be installed in English etc. It will work with a Windows or Mac and It will let you read the codes but not clear them unless you buy a full version but at the moment this is not required.

it is quite a nice simple to use basically plug and play and has the jaguar diagnostic codes installed in the program.

If you need a run through on how to use it I would be able to post a video for you.

 

+1 to Ducmon's advice. No need really, for even a laptop. If you have a Smartphone and $15, code-reading is within your grasp. Get a Bluetooth (or likely wireless, if you have Apple) ELM 327 adapter and a free app to read and clear them. I'm Android, so familiar with the app "Torque." I use "TorquePro" which cost me $5.95, I think, even though several years ago the free version, Torque, would clear the codes as well as read them.
Sorry, not familiar with Apple iSillyness, but I'm sure similar Apps are available. Just beware they are stingy with their BT, so you will probably need a wireless OBDII Adapter.

The advantage to going this way, is you can record live-data, as your car is running, which may help members here diagnose your problem.

 

I suggested the French program because you can also use it with a smart phone and iPhone and then you can download the information to the pc program to see it better. a very useful feature to us older half blind drivers

 

Hi hun,


Definately get the codes and then we'll see what we can do to help.


(And I'm a girl, but I've had most bits of my Jag in pieces, rebuilt or refurbushed them myself including the transmission, dash electrics, front and rears suspension... lots. The wonderful guys (and girls) here will help and soon you will know lots about cars and save a fortune in the process )

 

Just in case - any codes starting P1 tend to be wrongly described unless you use the jag info.

Also, the real jag info (free download) gives you the known causes per code.

 

Do you have news for us so that we can help you?
