Alright all!

I am back, so this is my fourth and hopefully best rover... (fingers crossed)

It misfires in cylinder 4, the plug was caked in carbon... CAKED, lol

I had the codes pulled and this is what I found

Po130
o2 bank 1 o2 1
(does this mean replace it?)

p1590
could not give data because the unit would not read it
what does this mean

p0304
cylinder 4 misfire
(duh) is this the echo effect of the other codes?

p0150
o2 bank 2 sensor 1
(does this mean replace it?)

I find it odd that only one plug is fouling out with carbon,
the other plugs looked a little hot, but okay.

I could use some hella help!!!! I want this rover to work,

THANKS GUYS

 

Start with a good tune up, that is Magnecor plug wires and any spark plug you want.
I prefer Iridium plugs, other prefer Bosch, others yet Champion and NGK.
www.apexperformance.net has the best price on the plug wires.
bimmerforums will get you a 10% discount.
Once that is done clear the codes and see what, if any, come back.
90% of O2 codes on a Rover are tune up related.
