Engine problem, not sure....?
 
well got some wierd stuff going on,
first thing in the morning ill start my car to keep from it running cold, it stays lean until i go out to drive it then will hold near rich, while driving. then when i let it idle afterwards itll be riched out
while its sitting in the driveway its blowing out steam which i assumed was just water vapor, but on the ground theres a bunch of little black spots inside the wet area on the ground.

then when the cars been driven around and i get to where i gotta be( in the past would count to about 30 sec. and turn it off, but would seem to flood, and id go through the deflood proceedure) now i count to 30 sec. rev to about 4k then let it run down to about 1400rpm and turn it off. and it would start fine after that. it started doing it again despite the rev up, so i thought plugs, they were done for so i swapped them. but it is still doing it. it seems to be once the engine has cooled enough it will start, but if not i have to do deflood...

also and im not sure if it matters hot or cold, but while the car is sitting and iddling the engine will drop from 950><, to 850><, and puff out what smells like an abnormal amount of oil burn........

anyone?

if it's flooding like that, maybe your compression is getting low. have you tried a comp test?

R.O.D Oct 29, 2008 06:44 PM

no i havnt yet...hmmmmm

yea most def check you compression, also your injectors may be leaking its not probable but its possible still.

R.O.D Oct 30, 2008 02:20 PM

kinda have my money against loss of compression, there doesnt seem to be any power loss, even at only 5psi

I need clarafication...Is it spitting oil spots and such out the tailpipe?


Is your oil meter pump stuck open?

R.O.D Oct 30, 2008 07:19 PM

ya i think it may be that, and ya its out the pipes, i thought i might be wet carbon deposits,

ill have to check to see if it is stuck

R.O.D Oct 31, 2008 06:56 PM
