Cruise control useless

I have an 04 DC with the 3.4 V6. It seems to have enough power, but when I use cc on anything but flat ground, it will upshift way too often.

Seems like a lack of torque at hwy speeds 65-75 mph. Anything I can do to help it?

 

Never probably. I bought the truck last december with 65K miles. It has about 90K on it now.

I thought about doing the plugs myself. I saw some Bosch platinum 4 tip plugs at O'Reilly's and thought about getting a set of them. Need to change the fuel filter, do a tranny flush, and maybe a timing belt/water pump job.

 

My 03 did that when I used the CC I would turn on the ECT button that help holding the speed.

 

Thanks, I'll stick with them. Did I read a how to post on swapping plugs that said they came with Denso on one bank and NGK on the other or am I dreaming that?


Thanks also for the ECT tip, I'll give that a try too.

 

Nope, you're not dreaming it. This is how they come from the factory, many theories on this and no reasons why from Toyota.
I have a theory on this but it involves BigFoot and the guy on the grassy knoll, but we'll just leave it at that.

 

Not sure about the grassy knoll thing but I had a big foot sighting.......

 

mine does the same i changed plugs, deck plate w/ k&n, magnaflow cat back it still does it even w/ stock tires if you figure it out let me know
