Multiple Misfire (7 Codes)
Hey guys.. Need some help with a little, well, big issue we encountered here. I searched google and managed to find a few cases related, but no answer or solution.
Condition: CEL would start blinking.. car would start bucking/jerking at around 2500 rpm. Eventually it would ease off, and then start again at a higher rpm. (depending on if you're on the highway or something)
All ignition coils were replaced last year. Air filter is new. Did not check MAF sensor yet.
The timing needed to be done so we got that done last week. Mechanic said the timing is spot on and is not the issue here..
Could anybody point me in the right direction here? I don't mind takin git back to the mechanic to have this resolved but If it's something I can work on myself, that would be great.
CEL CODES: P1300 P1305 P1310 P1315 P1320 P1325 P0305
Thanks again!

After a bit more research, forgetting the Igniter codes for now.. could #5 be the culprit here and setting off all these codes? Why wouldn't any other specific cylinder codes appear other than 5?

This is a classic bad coil description. One bad coil can cause multiple codes (although they are usually P03xx codes). Given you changed the coils recently, not sure what to tell you. Try switching coil 5 (right rear) to a different position, clear the codes with your code reader, and then fire her up and see if the P0305 code changes position. If it does, you got a duff coil, if not then you have some more trouble-shooting to do. Search the P13xx codes on this site (RX300 sub forum) as I've seen these posts before.
