87 N/A ...rough idle

ochowdero · 09-05-2010, 08:46 AM

so i got a 87 N/A and on occasion it will have a rough idle when i start it..
most of the time it starts up fine..(it actually starts up better from a cold start)
sometimes itll have a rough idle and shut off..

oh and the idle is at 450 500 rpms...
i bought lucas fuel injector and carberater(spell check) and put that in..
seem to work for a bit..

it feels like i lose alil power also...any help please!? haha
its my daily driver and id like to make it better..
thank in advance :P

check for vacuum leaks along the intake system.

here is the troubleshoot for rough idle / stalls in the TSRM

do some testing then come on back.

just to note...
i wasnt paying any attention to my car past couple days ive been so dam busy
and i just noticed my radiator light was on..
so i checked my radiator and my reservoir and filled it up then id thought i mind as well check my oil....
wow i felt so stupid not to think of this in the first place...
absolutely no oil! wow >_<
bad bad bad
its all better now,
just gotta check all that next time

for everyone..make a personal note to check your oil every month!
so you dont run into this problem or even worse.. blown engine!
