I just got a 2002 XG350, and it was having an intermittant P0305 code (misfire cylinder #5), and thus rough idle and LIMP home P1191/1193. I then cleared the codes, and for the past two weeks, it would intermittanly give the same codes.
She has 90K miles, and since there is no record of a tune-up, I decided to "set a base-line" and replace all spark plugs, spark-plug wires, coil-boots (not the coils), and the air filter, and swapped the #1/2 and #5/6 coils to see if the P0305 moves to another cylinder.
She started up fine, and was driving great (smooth, good power, etc.) for about 20-minutes.
When she was shut-down for about 10-minutes, I restarted, and instead of the RPM needle automaticlly going past 1K, it went into a rough idle, and eventually threw a Check Engine Light (CEL), but instead of a P0305, it is now P0350 (Ignition coil primary/secondary circuit malfunction). I checked all connectors.
After running rough for about 3-minutes, she was running smooth as silk again.
Any ideas ?
Should I just replace all three coil-packs ?
Lastly, the dealer say there is NO fuel-filter to be replaced, as it is part of the pump.
However, I read there is a fuel-filter behind the right-rear wheel. What's the real deal here ?
Thanks in advance!
