Ok to not change out all spark plugs at once
Ok I've been trying to fix a mis fire on cyclinder 2---I decided to first change the spark plugs with Bosch Plantinum 4's.
I was able to get the first three on the left hand side done but can't get to the fourth one and all the ones on the right.
It looks like Champions were on there. Is it ok to drive the car with Bosch and Champion plugs?

NO!!!
What year truck and how many miles?? The Bosch is a great way to go but they won't be happy on old Rover plug wires so how many miles on your truck/

BTW, what is stopping you from reaching that last plug? Is there a cylinder-looking object in the way, which would be your secondary air control valve?
To second what DiscoMike is probably going to recommend, is that you change out your wires for Magnecor 8mm, because that is most likely your problem, not your plugs; although the plugs could probably stand to be changed also. 90% of the time a misfireis caused by a fault in the wire. We recommend magnecors because they are carry more voltage than stock wires, and they are more reliable.

Hi Guys:
Thanks...I just can't get to it with my hands. I'll drop it off...spoke with my mechanic and he agrees that it's most likely the wires causing the misfire. That job is a little over my head. I thought I was somewhat mechanically inclined but I guess I'm not.

Well, if you haven't ordered the wires yet, call Tony ar 650-365-4145 and order a set of 8mm Magnacor wires, this is the best way to go and far better then what the mechanic may install.
Why don't you save a bunch of money and install the wires your self? As long as you don't have secondary air, n emssion control device, you can do it in under two hours and save $ hundreds.

You just nailed it Mike. Mine has the secondary air (you know, California [sm=smiley24.gif]) and let me tell you, changing the wires would be impossible without removal of the intake manifold.
