truck cutting out and missing at idle!!
My truck has had a little miss for about a year, but lately it has became worse, i usually run with my chip off and today i turned it on i placed it on the 9th setting and at wot my truck bucks and cuts out, and an excesive amount of black smoke comes out. more than usual, you notice this problem on the three highest settings. my lift pump psi never drops below 14 and i recently replaced the apps. so i dunno whats going on. oh and it takes my truck a little longer to start like a hesitation in cold or hot weather. it also smokes like a bluish color when i first start it and sometimes white too.. could it be injectors? my vp is has about 50,000 on it and the Lp never dropped below 14 psi.
what could be causing this guys, i need your input
