im trying to diagnose a problem on a friend of mines car.
its a 2000 3.8 firebird ~118k on it.
car runs fine under light throttle and idles normally.
but if you hit it kinda hard at idle or even a little at speed itll start to stutter. it feels a bit like a misfire or something. the exhaust doesnt smell like excess fuel like a non firing cylinder would though.
already replaced the fuel filter. replaced the air filter and checked the intake for any problems.
it was getting a misfire on cyl5 according to an engine code, replaced that and it hasnt come back. no other codes.
im not noticing any vacuum leaks.
thoughts?
