88 MJ high idle and reverse issues.

So the 88 my son and I have been working on has a very high idle. It appears to be drinking gas. The other issue is reverse in the aw4 works after it warms up. Thoughts?

Re: 88 MJ high idle and reverse issues.

Did you do cruiser54 basic renix trouble shooting? If not I would start with that.

As for the AW4 could possibly just need a service. Any idea on the last time a fluid/filter? other thing would be swapping soleniod and see if the problem follow .
