okay, so i have the d16z6 engine in my del sol, i just rebuilt the head and got everything back together. it starts and runs but the problem im having is that it is high revving around 1500rpm and does a little rev fluctuation. is it the timing or is it something else?

 

Did you make sure that all the air is bled out of the cooling system?

Is this 1500RPM at cold idle or after the car warms up?

 

its at cold idle, and oopppsss i knew i forgot something! let me do that and see what happens. and sorry new to the honda scene

 

clean you'r iacv if you din't allready. do you have a FITV also ?

 

Check for a vacuum leak too.

 

Yes.

 

got to bleed it out, car is doing a lot better. thank you very much
