Two mechanics and I just finished installing a vortech aftercooled supercharger kit and a type R intake manifold on my 2000 civic si. After we were completly finished, we did the final checks; no fuel leaks, no vaccum leaks (as far as we could tell). When we tried to start the car it immediatly started to rev by itself and I had to shut it off before it reached the rev limiter. We spent an hour trying to figure out the problem but to no avail. Does anyone have any suggestions on what might cause this? Any help would be greatly appreciated.

 

new intake manifold moved the throtle cable ? just a thought but with three of ya working on it you probley checked that already

 

Make sure your maf and tps sensors are not switched.

 

i heard that vortech were having some probs with there superchargers. umm the best thing to do is check wit da comp, and see if they have some sort of recalls on them!

 

is the trottle cable tight?? hmm....sounds like some type of a throttle problem...good luck

 

since you chnaged the intake manifold, check on the torque specs of the manifold.... if worse comes to worse, take the manifold off and put a new gasket on... then add some gasket sealent...
