We are running a D16Y8, with a Z6 intake manifold, with the Z6 throttle body, with the map mounted on top. Now for some reason, I am getting code #3, and i have a very lacking top end, and an annoying stumble in the revs. Like if you hold it at a steady rpm, it is popping and stumbling, and just souns horrible. Getting hoffiric gas mileage, and man its just so shitty right now. It was an HF, and we rewired it for the Z6 map, and it worked great on the Z6 we had in there at first, no problems, but when we put this Y8 in there, we had a bunch of problems. We tried other ECU's, MAP sensors, everything. We are getting 4.8 volts from the map. We have traced the wires from the ecu to the actually sensor. Any ideas? Much apprecaited..

 

put the wiring back to stock and use the stock MAP sensor... jsut leave the sensor in that hole to cover the vacuum hole, and run a T somewhere to run another vacuum source to the stock map sensor.

That's my suggestion. I hate the ON Throttle Body MAP's. Guh.

Here's what I did: BTW, I got the nipple from F-Max.

 

we have the wiring back to stock, but the hf map sesnor has a 5 wire clip, rather than 3 so we have it to stock si. We will try and do that later, to t it off, and see how it works...
