Re: engine problem?
Sounds like a vacuum leak to me, cause when you have one, the motor will pings and peg like as if its air fuel is off... I found this was the problem when I first bought mine. It was just because the breather tube from the valve cover on the passenger side to the the plenum was dry rotted... You know how it's got that lil 90 degree hose that connects to the plug that connects to the valve cover ya that was it... Also the cold air intake was loose so had to tighten that up to... So I'd just look around or get it pressure checked, however ya wanna do it, hey maybe even ur runnin lean but I really don't wanna say that to worry ya. Try Changing the fuel filter, heck run it to auto store code check it see if they pull something up idnk just tryin to advise ya...
