NEED HELP!!..cant find the problem

[skyyred]

ok so i have a 240sx with a s13 sr20det redtop...when im driving at normal speeds it feels fine, but if i step on it, it'll speed up for about 2, 3 seconds then it will start bucking...it only happens when im gunning it

im thinking it could be my CAS because i tried adjusting it and running it and a slight change in position would change how long it would take for it to start bucking drasticly (i would be able to gun it longer before it started bucking) but if it were broken the car wouldnt start so im lost.........

the car feels smooth at normal speedsit idles finei checked:- fuel pump - timing- sparkplug- cat- fuel filter- TPS- made sure car had good ground- MAF i will appreciate any help

Hey man, sounds like a timing issue, make sure its set at 15* from top dead center

[skyyred]

yeah... i thought it would be timing too, i checked it already its fine

[Morgs]

hmm weird, i would deffinetly think that was it, checked for vacume leaks?

i kinda had a similar problem when i had a crapy o ring on an injector, so if u can pull those and check them out do it, might turn out to be ur problem too

[skyyred]

thanks ima check the injectors i only tried unpluging them to make sure the were working..

[skyyred]

do you think somethink can be wrong with the CAS....because by adjusting it, it ALMOST went away.. but just moving it a hair it would start bucking even sooner....

[Morgs]

it very well could be, im no expert and not very familiar with it yet, best bet is to just keep tryin things, if u have a friend with an sr, swap parts, till ya get it. otherwise like i said try em, mine had a leaky gasket so when i would try to get on it, it ran like absolute ***, stuttering and bogging.

You have check for vacume leaks right?

when its running and u go by the exhause does it smell like fuel big time? white smoke?

[skyyred]

nah i dont get any smoke at all besides the normal and it smells normal...a friend checked my lines with carb cleaner...what would be the best way to do it???and thanks man im stressing out of this *&$#..

[Morgs]

best way to pull the injectors? or what?

just be careful when u do cuz those o rings arent the toughest things in the world i know that if they are bad o rings u can us the rings from a TT z32 i believe
