You could switch one coil from one of the other 5 ignition coils and put it on cylinder 2 and see if that is the issue. How soon did you get the CEL light on that showed the 302 code when you left the dealer?

Switched the #4 & 2 coils....it was the 2. $87 for new one...couldn't wait to save $20. Also changed out all plugs to NGK...car "was "running" like a top. Shifting was much faster.
That was 2 days ago. Yesterday after gassing up...hit the freeway to head to San Diego...engine light came on. Have to borrow the hand held for a re-check. Pissed off I am although I had a guy not only change out all the plugs but coil as well for only $80. It's damn hot here in CA and to get to the back plugs it's all by feel...patience and very small tools....with TONS of sweat. He's gonna change my rear brakes for $30.....Hey! if he's got the tools and the price is cheap...by all means. If I can do lighter things with tools I already have..which isn't a lot...I'll do those. Me...not full time DIY....lol
New engine light hasn't come with the previous shaking so I wonder what the deal is.

Just used the help here to fix the number 3 coil on my RX300.
Had P0300, P0302, and P0303.
I figured that since #3 was the hardest to get to, it was probably the bad one. Parts store only had one coil, so I got it, busted my knuckles getting the thing out, then in, cleared codes and fired it up. No more codes after test drive.
Just signed up to say THANK YOU! Appreciate the advice.

Lexmax, thanks for giving me the confidence to pull coil #3 out w/o taking anything apart! It was tough but if you didn't assure me I wouldn't haven't even tried. So, I swapped #3 w/ #2, as of now it's not coming up on the computer. I'm going to get another coil for the #2 and see what happens. The car is still rough hopefully because of that bad coil that I'm replacing today.
I'll keep you posted, thanks again.

You can do so much as an enthusiast. There comes a time when you have to go for a professional debugged possible repair.
