Hello guys was wondering if you can help I did a vtec swap on my 94 accord out of a 95 what I did was take the head and connect the vtec computer to it and take the oil control orifice out I used the external coil distributor cuz it's the only one that worked and when I turned it on it revs all the way to around 4 and back down to one ccontinously can anybody tell me why it does that thx

 

Sounds like there is a vacuum leak causing the problem. Bad gasket, broken or disconnected vacuum hose you will have to check for leaks.

 

Well when I swapped the head the intake manifold stayed in place I only disconnected one or two vacuums so I'm thinking it's got something to do with computer or distributor or something I really don't know

 

Sounds like its in limp mode. Check for codes. Did you run your two vtec wires to the ecu connectors ?

 

Well it's only one isn't it the the one from the solenoid to the a8 pin

 

As stated it sounds like a vac leak.

If you are sure it is not from the gaskets (?), then check all of the vac lines coming off the intake. Also be sure the PCV is fully seated and the line to it is ok.
