2000 gs300 with a laundry list of trouble codes..
Hey fellas whats really going ! been a new member for awhile and made a purchase for a used ABS pump assembly on here last summer (which was a smooooth transaction by the way), usually just looking around into the suspension forum to address the infamous front end noises/clunks/vibrations...
But on another note, I'm having some issues with my GS300 with 146k on it.
p0300 -random/multiple cylinder misfire
p0301 -cylinder 1 misfire
p0303 -cylinder 3 misfire
p0441 -evap code
ive replaced the spark plug with NGK iridiums (which are supposed to be OE equivalent) new OE plug wires and 1 new OE coil for cylinder number 3. and 2 new coil boots for the other 2 coils. i cleaned out that "spark plug valley" which had oil and debris in and around all the spark plugs, slapped it all back together, and still the same sh..t LOL. Oh yeah, and a new gas cap to address that EVAP code. And to top it all off, the VSC lights stay on and i can hear the ABS pump cycling at just about every stop i make.
the start ups on cold mornings are rough for about 30 seconds, then it kinda even outs. but theres still a slight misfire at idle. ive cleared the trouble codes just out of frustration and the car can run with no CEL/VSC lights on for about a day.
any help?? thoughts or suggestions ? im thinking about just doing the other 2 coils next week and seeing what that does, might aswell. if that doesnt work then im just gonna break bread and take it in.

These cars use double ground electrode not sure if the ones you got are like that , check your connections on the coils since they get brittle and break easily, the VSC,and CEL will be on due to the misfire also the VVTI solenoid could be bad ,common problem too.
