okay i just replaced all my valves (intake and exhaust) on my motor...ended up having on my #2 Cylinder 1/2 of the valve head broke off before i bought the car....i cant see to find out what it is but from lookin from the top of the motor there is a a place to plug in a vaccum line idk what its called but i think the like goes to the crankcase? this is what my friend told me..i was wondering if with this being clogged...its right on my fuel intake where it separates into 4...i was wonderin if this would make it choke...

i was wondering if anyone had a picture of the DPFI intake manifold so ppl could see what im talkin about

thanks!!

yes its that V on the 2nd Intake port what the hell is it and would it cause my car to choke and sputter?

 

That is your PCV valve. The valve screws into the IM and the hose runs from the valve to the black box on the back of the engine. The purpose of the PCV system is to evacuate oil vapors from the crank case. Not sure if this is your problem or not.

 

well i just did a valve job...and now the throttle surges like goes from idle to 1.5-2k+ then back down then eventually stalls out...i dont know where to start

 

Check for vacuum leaks. Did you remove the IM from the head when doing the valve job? Is it possible you don't have a good seal between the head and IM?

 

i will check that...it was late at night and no place was open to buy a gasket for it...so we used...RTV gasket

 

I think we may have found your problem.

 

thanks...i went out andbought the intake manifold gasket and it works!! :D now all i need to know is how to Do the ignition timing..i think we got it right but isnt it supposed to be at 18 degrees for a d15b2? and if so yeah someone explain it to me thanks :D
