Now this is odd.When cold any type of load casues an almost constant very small backfires.I felt it before i heard it,had to roll the window and listen.Really robs of power.NOW all that being said as i drive it and it warms up it will still do that DAMN pop-pop-pop-pop .BUT if i go in to lets say the store spend just a few minutes get back in..no backfires and runs super strong..
???????????????????????
i did automotive forever and this has me stumped,it started this right after i screwed with the carb trying to lean it out a bit..SO i put it all back but it is still mad at me..If it was a customers truck id do a coolant combustion test to see if it had popped a head gasket but i know i have not done that..It pops thru the exh ..I had even Seafoamed it a month or so ealier and i was very happy that it did not smoke much at all...
So if anyone has ever run into this please jump in,anyone have an idea of what youd do if it was yours or hell at this point if you have a good joke jion in this thing has really wrecked my sense of humor...
