Find the miss

[daverunner]

Ok guys lets play find the miss. Symptoms of my generally bullet proof 2000 runner 4 wheel drive sr5.

1. Early A.M. miss
2. Poor gas mileage
3. Bucking at interstate speeds but runs like top in town.

1st diagnosis bad plug wires
2nd diagnosis dirty maf sensor
3rd diagnosis bad injector

I considered the plugs but they are Bosch Platinums...best you can get according to the parts place.

Any guesses yet?

Ok...lets play another game....One of these things does not look like the others

Ok the pic is too big so I will explain. I had 6 Bosch Platinum dual ground plugs with aprox 15,000 miles on them. When i finally decided to check them 5 were fine, 1 had both ground straps missing. Can't explain it. Don't know if they burned off, fell off or if Chris Angel "Mind Freak" got into the # 2 cylinder and ate them. Long story short I replaced them with good old made in the USA Autolite Platinum and she is once again bullet proof. I will no longer buy Bosch plugs. I will take a lower resolution pic and try to post.

those Bosch plugs don't really work with toyota's. I use NGK or denso plugs which work the best with my 4runner.

x2 i have seen brand new set of bosch not even let a ES lexus start. buddy bought them when they were cheap, and ended up back w/ the used stock ones at the end of the day. Can't explain what they do different, but NGK copper is what you will find in all of my cars.
