First I would like to say what a great forum a lot of very helpfull info found here!!

My problem is my 2000 3.2 gave me a code P0354 P0300 P0304when it started to run on 5 cyl. was running very rough, since then I replaced all the plugs (Boch+44482) reset the computer and the codes went away, I have smooth idle but when I"m drivingit's not 100% power still on 5 cyl.
what should I do next, I guess my last shot would be the injector??

Thanks for any info.
