my truck has been doing this wierd stuff for a long while now but it is starting to get a lot worse it would just do it every now and then but now it's doing it more often than not and i have decided i need to do something about it
sometimes when i take off from a stop it will pop just like a backfire and feel like it misses a beat then will drive normally untill the truck shifts.. then when the rpms drop and the motor loads up at part throttle (doesn't do it as bad if you let off the throttle or have it full bore) it will buck a few times and then drive fine untill it shifts... then it repeats
all the gauges read normal... i thought i had a fuel pressure issue but it stays between 55 and 60 psi all the time, i have tried multiple times to get codes off of it with a genisys system and with some other machines but don't get anything... it does it on all settings on my evolution and stock (although not near as bad)
any help would be appreciated... i have had the suggestion to replace the ICP sensor but they wasn't entirely confident that was the problem and neither am I... it has crossed my mind that maybe the HPOP has issues or possibly i have a injector doing something it shouldn't
