Meaning they could be a part of the rough running? Yes if skipped one tooth, but JagV's car ran smoothly sometimes. I bought a 2000 w/o knowing these cars. Now have to plan for 4k for replacing tensioners. Not an immediate must do (no chain slap or noise at idle) but still a big ticket item. Also having rough idle/warning lights problem. May fix and sell mine then look for a 2003-2006

Car delivered to me by transport company with low battery voltage and lots of related issues.
I have spent hours trying to figure out what I am facing
After bringing battery up with charging, the best it seems to hold is 12.25 volts.
I am able to get what I think is "normal" function of car electrical now....but not sure.
Car starts and runs fairly well, but I have been unable to get the check engine light to clear so I am not driving it much except to get it OBD checked.
First effort to get it checked failed....closest to me auto parts place could not get its reader to read the car at all. Next closest handed me the reader (due to COVID) and I connected it to diagnostic port.
Their reader was an INNOVA 5210. What came up on screen was "Global OBD2 Jaguar" and in red letters: P0300(1/6)Stored In black letters thereafter: Random Misfire Detected DTC Severity 2 of 3. Repair immediately if drivability issues.
Then in red letters: P0301(2/6) Stored. In black:Cylinder 1 Misfire Detected. Then in red letters P0303(3/6)Stored. In black: Cylinder 3 Misfire Detected; Then in red: P0304(4/6)Stored. in black: Cylinder 4 Misfire Detected; In red: P1316(5/6)Stored.in black: Misfire Rate Exceeds Emissions. Then P1000(6/6)Pending In black:OBD Systems Readiness Test Not Complete.
I have no experience with readers or even whether I got all that I was supposed to from the diagnostic tool. I have reviewed posts, but don't see a clear path to diagnosis or even if I have a valid test.
I would be most appreciative if anyone has suggestions or can point me in the right direction.
Thanks,

Thanks,
(fuses ok, reader powered up), cleaned pins, wiggled wire harness various places, etc, etc. I spent hours (days) trying to solve the problem. My indie (using Jag ssd) had no problems pulling both P and CAN2 codes. Very good shop. Got multiple P codes for misfire. Got CAN for defective ABS module. Disconnected it. Car now starts and idles smoothly. Are 2003-2006 cars more reliable? Shop recommends (also better engine and 6 speed MBZ trans).

Thanks, good suggest. If plastic looks ok, then I've got some time. Also, based on no noise at start or cold idle, I don't have to do it immediately. However do think they need to be done at some point. No, I don't do my own work anymore for multiple reasons. I can't see doing just the upper set because they are more likely to fail than bottom set. There's a nice 2006 convertible at local dealers for 10k. Higher mileage than I'd like (94K) but full service history.

Intermittent problems continue
Sorry for not keeping this situation current. The weather here was exceptionally cold for a couple weeks and I did nothing with the car but keep it on battery tender. I did purchase a new battery which I believe I reported in an earlier post. Since that time, the car has has few outings as I don’t trust it. I purchased a Foxwell NT 630plus code reader and pulled a code PO 442 evaporative system leak; P1637 & P1643. CAN link ECM/ABSCM circuit network malfunction; Fuel pump circuit monitor low input is what the cost de reader is suggesting. The antifreeze coolant plastic reservoir was found to be empty upon visual inspection although no light or warning displayed specific to that.
I am at a loss. No local to me Jag mechanic found as of this writing and I haven’t the time now to figure things out.

The 4.0L and 4.2L engines seem to be similar in reliability when well maintained and known issues are addressed (4.0L plastic timing chain tensioners) and minor problems are addressed before they become serious problems.
Cheers,
Don

Here are the definitions and published possible causes of P1637 & P1638:
Problems with wiring, connectors and grounds are more common than module failures, so it would be worth checking and cleaning all the relevant connectors and ground points. The CAN wires are Yellow and Green pairs. The ABS Module connects to the Transmission Control Module by way of the Adaptive Speed Control Module, so the connectors at those modules and any connectors in between would be good places to inspect and clean. Cracked, starved and cold solder joints on the circuit board of the ABS Module are very common and can usually be cured by sawing the case apart, reflowing and supplementing all the solder joints, and gluing the cover back on.
See the diagram of the CAN on pdf page 131 of the Electrical Guide, which you can download at this link:
Jaguar X100 Electrical Guide 2002
Here the info for P0442. The most common cause is a loose gas cap or a worn gas cap seal, but there are several other possible causes:
Your instrument cluster/pack (IC or IP) should display a low coolant warning before the reservoir is completely empty. Your lack of a warning may be related to problems with your CAN, or with the coolant level sensor.
Cheers,
Don

cracked primary guides = no problem, 99% of the time they fail with lots of warning

Thanks for the feedback. Still learning here. When the uppers fail, it means engine damage right? If it's so easy, why do shops charge so much? zip tie is the quick around that they don't want to use?
What happens if the primary guides fail? Time to pull covers and check if uppers original or replace (metal).

Let us know what you learn about your upper tensioners.

Car started misfiring again. Seller had recently installed 8 cheap, no name, coils. My indie replaced w/ Jag OEM's. End of problem. Lesson here is use high quality parts.
I drove for 1/2 hour today. Indie is going to do a 20 mile errand to make sure the problems are solved. That's customer service!
Problems solved with replacement ECU, Jag coils and rebuilt ABS module. Starts immediately, idles smoothly and drives well. Time for real gauges!

CA Jag,
Well done! Lessons learnt - beware the cheap replacement parts! This Forum has seen alot of them and some modern re-made parts seem really bad - the non-branded coolant expansion cap springs to mind.
Happy motoring.

Drove home today. Def a lot of fun to drive! It ran perfectly. Super smooth idle. No more warning lights/limp mode. My indie did a great job (even cleaned and washed the car). If you're in the Sacramento CA area, recommend Stewart's European Auto.
