CEL Error codes on 99 rx300
I just ran in to a problem today with my CEL flashing. I was at a stop light and after I accelerated I noticed right away that the truck felt sluggish and is if it was going to stop on me and the car was shaking pretty bad. I took it in to Advanced to get the CEL light checked and I have the following CEL codes: PO300, PO301, PO171, PO136, PO441, PO446. I have read in previous threads and correct me if I'm wrong but the code PO301 could be a problem with the coil pack on cylinder 1. I was going to switch the coil pack from cylinder 1 to cylinder 2 to see if the CEL moved and if so I would replace the bad coil but it started to rain (Stupid chicago weather). To give you a little backround on some of the maintenance I have performed are I have replaced the 02 sensor on the front of the engine, replaced the spark plugs with Bosch plug (which my brother in law replaced and I was pretty pi$$ed about) replaced the coil on cylinder 6, replaced the MAF and this was all performed about two years ago. I appreciate any help you can provide.
Thanks, Armando.
Thanks, Armando.

X2 X2 I agree, stick with OEM plugs, and that doesn't just mean BRAND, it means IRIDIUM since that's what they were built with. The BEST plug money can buy.

RESOLVED: Thanks to all for your response. I have changed the coil pack from Cylinder 1 to 2 and the code moved to cylinder 2. I purchased a new coil and replaced the bad one also reset the CEL and the truck is now running like a champ and it no longer shakes. Drove it around off and on for about three hours and the CEL light has remained off.
