Re: engine revving in cycles
Sweet Humtech is here!!
Ok, this is my info
2003 H2 with about 125,000 on the clock.
The cycles started a while back but no codes are shown
I have found out that it isnt a warm or cold engine issue now.
Basically I can come out the the truck, jump in, start it up, sometimes it will rev in cycles, sometimes it doesnt. One good push on the throttle and the cycling goes away.
I have done some research and believe that you are probably right about the throttle body needing cleaning.
Is there a specific chemical/ cleaner that you would suggest for this?
THANKS AGAIN!!
