so yesterdy i drove my car around town. going to class..not beatying on it..hit boost a few times but not like going full throttle and going all out on my motor. i let it sit for a few hours go to start it and its bogging and misfiring. i get new spark plugs in the next day drove it around for a few just to test it and it was fine..then let it sit for about 6 or so hours. went to start it up to go out and it boigs again and just dies. why do my spark plugs keep dying? i used ngk oem integra plugs. btw its a 94 LS motor with stock head and built block. turbo setup...sc34 turbo. i had this problem awhuiiillee ago but just switched sprk plugs and i was good to go. anyhelp is appreciated. thanks

 

why do you think its the spark plugs? Are they fouled? What color are they- black, white, oily, burnt? If it bogs down, I think you have other issues than your spark plugs. Also, how tight are you putting them in? I'm not questioning your intelligence or engine knowledge, but I just found a spark plug in my bike that was supposedly serviced by a reputable place and they bent one of the plugs.

Just saying.

 

leaky injectors? are the plugs wet when you pull them out? on a turbo car id be using colder heat range plugs too

 

If you are boosted, I would recommend getting some colder plugs. Personally I would go with NGK Iridium IX and depending on the boost level go either 1 or 2 steps colder.
