Said installation is on a 94 ex coupe, with JDM GSR swap, obd1.

Also have the skunk2 68mm throttle body and the hondata IM gasket, I got it installed and running with much help from the blox GSR IM install on the faqs here, but when I start it up with the heater on high, full coolant levels, and all sensors properly hooked up, it surges from 3500 to 2000 rpm with my foot on the clutch, and when I release it, the idle just sets right at 3500 rpm..

I havent really had a chance to fully warm the car up, I pretty much fired it up to make sure nothing was leaking, but the skunk2 tb has no fast idle, so shouldnt it idle low right from the start?? It isnt throwing any CELs either...

Is it possible that I still have a vacuum leak?? I hooked up all the vacuum lines in accordance with the instructions that came with the s2 manifold, and the only thing I left off when I put the new manifold on is the IAB solenoid, which skunk2 said is no longer used... Maybe I should let the car warm up and see if the idle will drop?? Do I still need to hook up the IAB solenoid??

Thanks in advance for any possible assistance

try to find the vacume leak. and throttle cable is not too tight or loose. tps adjust to the right voltage.

when i did the intake mani swap i forgot to install the pcv, my idle was high check your vac lines.

all vacuum lines are properly installed, but there were some of the lines that werent used, and those were plugged.. PCV is taken care of as well, does the tps voltage affect idle?
