engine sputters dont know solution

[burntricer]

check your CAS. or your CAS plug. i was having the same problem for over a year, and i got it fixed by changing the CAS plug.

My car was running perfect unplugged coilpacks left them connected to the harness did compression test then from there on i have had this problem.

when checking compression you are supposed to unplug your CAS and i guess its to not mess up the timing.... so double check your timing....and then check it again because my timing was a little off...i took it to a shop and my timing was all f-ed up so i quess my timing light is crap....they fixed my timing and it ran great but only for like 3 pulls....now it sounds like subaru so im going to double check my coil packs and spark plugs because now it feels like im miss firing on one or maybe two cyl. before it felt like just mashed a$$H*le$ and a lot of misfiring but now it feels a lot better....about 95% so it seems it was a mixture of failures

ok...new spark plugs seem to have fixed the problem along with some timing done....but it seems like it comes back few times...just every now and then...i cant even get it on video...lol...

it seems like it misfires on one of the cyl. but my fuel checks out and my coilpacks also check out on idle....how can i check while in gear and pushing it because thats the only time it misfires

i had the same problem except with an s13sr20 it was one of my grounds

i almost have this figured out....just one thing....should i need a safc to tune a completely stock s14 sr20det with a fmic and a greddy bov....???

sort of related to this post, how did you discover the bad ground and which was it?

I have been having a similar problem, one day it started, not gradual. i was suddenly [and still] running lean. i know this is a rough way to judge, but my WOT voltage used to be about .91-.93 fairly consistently for years. then one day, and now, it is running about 0.81-.85 . First thing i noticed was that when "getting on it" it would suddenly stutter and act like some sort of fuel/ign cut.

I have checked many items that i can list later if anyone wants to know all i have checked and what results i have... probably most of the common checks have been done. so I am running lean and am not sure why.

Takes place around 11-12 psi.
