A couple weeks ago i had some check engine lights, had fixed them by rewiring the primary o2, and the vss sensor had a bad wire connection. VTEC and engine was running great...after this past weekend, i was driving and the car started sputtering. And now it stalls out at stops, and spudders from 1000rpm - 4000 rpm, after that it is farely smooth untill i have to slow down again. What could this be, seems to have a blue'ish smoke coming from the exhaust at low rpms, and backing up. Not at higher speeds. Pulled the plugs today and saw one had some oil on it, and the other 3 were black, but not to fludded. Car is running rich but what is my bogging problems anyone??? have a similar experience????
lemme kno fellas

 

i'll make this short since we are talking over aim . . . piston rings man. Do a compression test, but what's happening is oil is seeping past the piston rings getting into the combustion chamber, and being ignited which is why you are getting blue smoke, and a oily spark plug.

If you really don't have the $$ for aftermarket stuff, just replace the piston rings and boost on

 

i was afraid of this being the first response...lol damnit!!!!

Damn, sending that motor to hell already.

Do a wet and dry compression test. Do a dry test first (with no oil) then put oil in the cyl. and see if the numbers go up. If they do, it is your rings.

Is there a CEL?

 

Damn, that just hurts hearing it.

Hope this isn't the car your trying to sale.

 

update...

no problems internal. It is black smoke comin from the exhaust not blue, it is running really rich. When the check engine light is on for my egr valve, it runs great...when no check engein shows...it sh*ts the bed all the time...
any ideas i would greatly appreciate...

i am running a p13 stock

 

bump throwing code 7, TPS(throttle positioning sensor)....could this cause my bogging??

 

yeah from experience, TPS gives you really bad idles and the motor splutters and sometimes just stalls

 

yeah.. i was thinking something with the throttle body... once u fix ur tps, if the problem still persists u might try tightening ur fast idle valve on the very bottom of the tb then try adjusting ur fast idle screw. sometimes they just get off alignment....
