K, we were moving this weekend so i put on over 300 km on the car these 2 days , now once i start it after a drive i notice a bit of black smoke coming out of the exhaust for the first 10-15 seconds and the rpms are way low at 400 - 500 rpm , after these 10-15 seconds everything returns to normal , and the car runs fine. and i rebuilt the engine about 5 month ago , so i dont think it might be the rings....., another thing i noticed is oil in , and around the PCV valve , im not sure if it's suposed to be there , anyways , last night it also gave me a code 33 , and im not sure what it means , its an 88 camaro 2.8 mpfi , 5 spd . can anyone help me with any of my questions

thnx in advance
:hail: :hail: :hail: :hail:

 

I believe black smoke means you're running rich. Sorry for the lack of help.

 

i got a code 33 once...thought it was my Mass Air flow sensor...replaced it a few times...turned out to be the relays located on the firwall in front of driver seat...one for power one for burn off....most like;ly the burn off...

 

k, thnx for te responses , ill check the relay today after school, btw , its the second time it does at code 33 thing , but another question, if im running rich , how can i fix that ........

 

All except 1989 and earlier MPFI V6 and TPI V8:

MAP Sensor: Leaking or restricted vacuum hoses, poor electrical connection, open or short in circuit; defective MAF sensor; defective ECM

1989 and earlier MPFI V6 and TPI V8:

MAF Sensor: Poor electrical connection, open or short in circuit; defective MAF sensor; defective ECM

Hope that helps.

 

thnx for the response , i have the Hanes manual with all the codes in it but sinse were moving i coulent find it anywhere, so thanks. now..........
MAF= mass air flow sensor right ? , that flat rectangular thing on my intake duct ? or is that the MAP ? , so yes, ill check the relay as soon as i get out of this class and go home ,

 

K, i did try to check the MAF relay , but um. where is it .....
and what explanation can u come up with about the oild in and around the PCV valve ??? , im so confused now , can anyone help ?

 

The PCV valve is not immersed in oil... but it still gets splashed under the valve cover... if there's oil inside the hose then the valve is shot and needs repacing

 

its a fairly new valve but ill replace it anyways , so still, any advice on how to find the MAF relay ?

 

Thnx for all the help everyone , today i bought another SC for parts and replaced the MAF, its been running great so far , so i guess my problems are solved , thnx everyone who read and responded to this post :lala: :lala: :lala:
