running a B18c1 in an 88 CRX si with a chipped B16 (OBD-0) ECU.
the car was running fine for the last few months with the GSR intake mani (with butterflys), but idle was a little rough due to what I thought was a faulty TPS (that wasn't reading 5 volts at idle)
last night I installed a Skunk manifold and when I started the car up, it wouldn't idle. I had to adjust the screw on the throttle body all the way over in order for it even idle at 250rpm. The check engine light also came on, and the ECU went into limp mode and it was burning crazy amounts of fuel. Clouds and clouds of black smoke out the exhaust....
So what is going on? Why would the install of the intake mani change the running of the engine so much? Is my TPS at fault? Any help would be much appreciated! as I have to get my car going again to get to work.

First, check the code and that will narrow down the potential problems.

My guess is the IACV is causing the problems. It'll be a code 14.

one long flash followed by four short flashes is a 14.

thanks, I'll check it when I get home. If this is the case what would be the best way to resolve the problem?
