Hi, Everyone i am new to the site and need some information, i have a 2002 chrysler neon 2.0 lx auto. car had done 73000 miles the guy i bought it off said he had had a oil chane and gearbox oil changed, i thought he was just looking after it. but not had it long when it started intermittent problem it starts loosing power and struggles to change down gear, then its ok again, and when i am reversing sometimes it cuts out and then its ok again. anyway i just had it mot and they said gearbox was wet with oil, so decided to change my plugs 3 seem to be ok but one is really bad and looks burned out, see pictures should i be worried any information would be appreciated thanks.
