I have already been through all of the components you mentioned & the 2000 XJ does not have a cap or plug wires. It has a coil on plug rail & uses a cam & crank sensor. I know what the trouble codes mean, you should read my previous posts before you comment. Thanks

Want to buy a XJ with a 5.5" Rubicon XDuty lift? Ha Ha Ha.... Need new ideas........

Also, put heat shields on all 6 injectors

yes, on the last drive it was running smooth, it doesn't always have the missing & not reving above 3k, only when the CLE is flashing & that only happens once or twice a week (intermittent), but always turns on the CLE p0304. As stated in the previous post, new head, injectors, crank sensor...

Checked and cleaned all grounds. .2 ohms resistance between all points, cleared codes p0300, p0303, p0304... Road test, ran smooth but after 20 min. or so the CEL came back on..... p0304 as usual. Not idling rough or noticeably missing though. I am stumped. any other ideas?

I will give that a try. the one at the dipstick head is covered in grease. I will let you know... Thanks

Just verified that the camshaft synchronizer was in perfect alignment per the directions you showed. So now I have ruled that out, what is left? I still have the same p0304, along with occasional sputtering, no revs above 3k rpm, and blinking engine light. Turn off engine and it goes away. I...

Thanks Tim MN, I will try the synchronizing first, and then if not resolved I will use your troubleshooting recommendations. Much appreciated

gradon, thanks for the article. I will check the cam synchronizer. I wouldn't have thought of that, although my XJ has never stalled or not started it does have the missing and clearing up upon restart. Thanks

I replaced both crank & cam sensors last week, but didn't help. I even cleared the PCM, or ECU whatever you want to call it to reset the adaptive memory but problem still exists. I am really puzzled today by the p1694 code... At a loss for ideas.......

I am hoping to get some help with my issue. I have a 2000 XJ 4.0l 134,000 miles and I have been trying to resolve a check engine light issue. It first started after I overheated due to a blown head gasket, cracked the cylinder head and had it replaced. A couple of days after getting it back from...
