Hey there, new to this. I have an 02 S-type 4.0L as a second car, and it's giving me some troubles. It stalls out in the middle of driving it sometimes, like you can press the gas and nothing will happen for a bit then it kicks back in and starts driving. It sounds electrical to me. It had the same symptoms before when I had a bad #2 coil. Replaced it then and it went away.

My mechanic read the following 3 codes:

P0308 - Misfire Cylinder 8
P0430 - Catalyst System Efficiency Below Threshold Bank 1
P1383 - Variable Cam Timing Overretarded Bank 1

P0308 - I've had the misfire cylinder code on #2 before about 6 months ago, replaced the coil and it went away. I remember reading that the 02 s-types had probs with the Coils.

I've no doubts it's the #8 coil for this problem, and even better Drivewire has a whole set of 8 (16) for only $100 so I think i'll replace them all this time with new spark plugs.

P0430 - Mechanic said to just pick up a new cat for bank 1, which I can find for about $218-$250 for this car on drivewire, any other ideas? Could my 02 sensor be toast also?

P1383 - Not sure what to do here, Was hoping some insight?

Thanks in advance if anyone can help out, would like to get the parts ordered up asap.

 

I recently had the p0430 code pulled up, and it said the same thing. I also had a misfire in the 6th cylinder and the egr valve went bad. Thus far i changed the spark plug, boot, and egr valve on mine since then the p0430 went off. I still need to replace the coil on the 6th though. Now I don't know if changing those fixed it, but here is what i've been told from all the phone calls to jaguar. Jaguar said thats p0430 is the death code cause it means you have a bad cat, it also may be an 02 sensor thats saying the cat is bad. The one thing you can do is take it in and have a specific test ran just on the 02 sensors, if those are all working then more then likely its the cat. As far as the coil goes since you've already replaced it you can take that to an auto place not auto zone or anything and they can run a in depth test you may have a fuel injector problem, compression, etc. The p1383 code I have no idea on, sorry about that.

 

A misfire is usually the coil on these cars.
