tune up went great but...
truck sputters now and says engine failsafe mode. i tried reinstalling the hypertech programmer(tried the day i got it used to) and it gave a tone saying engine failsafe mode. did the same today after i changed the sparkplugs. put all the coilpacks back in the same hole they came out of and used dialetric grease to.
