ATV Racr-IDI Driver
Y' all have always been a huge help in the past , and since I still own an IDI i figured I'd see if you have any ideas...
I have an 82 K20 with a 6.2 th400 4.10 gears and 37 inch tires. I have run this setup for over a month and had no problems until now, Last week I went to the mountains and got my truck buried in about 3 ft of snow up right near loveland pass CO, ( alt. 12,000 ft.) I had to leave it over night and we finished the recovery the next day, but while attempting to start the truck, it wouldnt fire. The temp probably dropped to -10 or so over night up there, and I was running B20 BIODISEL . After about 5 or 6 failed attempts I had my buddy run into town and get some anti-gel. After a couple battery charges and some more cranking she was running. Since this trip i have noticed that when I travel at freeway speeds after about 30 mins or so the truck begins to sputter and blow white smoke when I apply more than half throttle or so. I thought that maybe the electric lift pump was the cause, but I changed it and after 30-40 mins of freeway driving the problem was back. The slow speed running hasn't changed ( although it died once idleing, which isnt usual) I was wondering what could cause this since the truck runs perfect for a while, can it be related to the geled fuel, even though that was 4 or 5 tanks ago? Please let me know any ideas and I'll be happy to provide any more info...Thanks!!
