I'm getting these codes on my 2000 Jaguar Vanden Plas. I know that code 0353, 0354, 0355, 0356 are coil codes. So I moved coil 3 to 1 and 4 to 2 and coil 5 to 7 and 6 to 8. Still getting same codes with an additional P0358. I hoped the misfires would move but didn't. What should be the next step I take?

 

That's very much the same symptoms I had when my ECM failed.

First, be certain your battery is good and all of the connections are tight and clean. I expect they are, as low voltage also causes several other false DTC's.

If you can eliminate the battery and connections, it's possible the ECM is at fault. I sent mine to Automotive Scientific in Tn. where they will test it for about $55, I think. If it is bad and can be repaired, the test fee will be applied to the repair cost.

I'm going to send the ecu to get repaired tomorrow. Will let you know.

 

Did these codes start immediately afterthe timing chain episode on this car, or did it settle out, then all of this started?

 

I had the ECU checked and repair but I am still getting the same codes.

 

I'm not quite sure. I was getting a lot of different codes before I had the battery charged completely. I was considering that it could be related to me switching out the actuator but I did everything correctly except using the crankshaft locking tool.

 

So, is it timed right now? DO you have good compression in all cylcinders?

 

I have not checked. I guess that will be the next thing I do, check the compression on the cylinders. What other issues could it be? The car drives great until it goes into restricted performance mode. I moved the coils, had the ECU fixed. I haven't changed the spark plugs or fuel injectors. Could it be one of these?

 

Update: I drove car for a while with these issues still existing. The car would go in to restricted performance every now and then till I was on the highway and it finally threw a rod.

I found a engine on ebay with only 62K miles. Having it replaced next week.

 

Sure sounds like a timing problem. What's the history on the tensioners?
