well, I have only had my truck about a month, and I got around to replacing the spark plugs today. it ahs 88k on it, and was over due, as the plugs and wires were orginal.

The plugs were horrible, the ecectrodes were worn down to almost nothing, making the gap at least 4 times what it should be, and I had alot of ash deposit on them. After changing the plugs and wires, I took it for test drive, and wow....easier start, quieter, smoother idle, and more power!!!

One question, I am having trouble making the new wires stay on the distrubutor, it's like they are slick, and they want to slide up on there own.

Any suggestions?

 

What engine do you have?

1997 XLT Teal 4.6L Flareside 4x4. Automatic, Reg. cab, tinted windows, bug deflector, Dual exhaust, K&N Generation 2 air filter, BullDog keyless entry/remote start(installed myself), Custom 16" wheels, bedliner, Covercraft tonneau cover, electronic shift on the fly. Going to add headers.

 

I have the 300 I6. it's freakin legend of a motor.
UNSTOPPABLE~!!!!

Although i think I might have a very TINY rear main leak. I have heard that the 300's are known for it.

 

Try to rough up your towers a little bit, it should help. What year is the truck??

 

I know it's been a few weeks since you posted this. I had a 95 with the same motor. I put the split fires in it. I had no problem getting the wires to stay on the distributor.
