Hey guys, its been a while. I've been 4x4ing my 88' pickup alot this summer and i am begining to notice an abundance (or respectable amount) of power when she is cold or at that first start of the day and then a LACK of power when it reaches operating temp. Its not drastic, but does usually make a 1 gear difference on certain hills where i live or when out in the bush. Haha yes, i will admit im runnin 35s with stock gears <img src="/forums/images/graemlins/drunk.gif" alt="" />. I have heard of this problem before and im 95% sure its not a overheating issue. Can anyone shed some light on this? Thanks.
