so i just did a d16 z6 swap in my car.

originally i did an mpfi swap. i got a p06 converted to vtec ecu. its chipped with chrome. i just got done doing a full motor swap etc.

the cars revs when i start it to 4 grand and bounces from 4 grand to 2 grand.

ill post video

but what are some things to check.

im almost 100% its not a vacumme leak

the coolant would make it that crazy of any idle right

the ecu does have launch control set it in.

my car is an 88 crx and doesnt have the clutch switch thing. becuase it used to be a dx auto.

sorry more details in a few..

have you checked for vaccum leaks?

why are you so sure that it isn't related to a vaccum leak?

Try the brake booster vacuum,That was a mojor problem of mine in my 91 hatch and also check ur tps and the throttle body,Some will cause a high idle.
