Has anyone tried the OBD2 intake manifold on an 88-91 SI? Problems?

 

You mean the Y8 intake manifold right? If so it has been done plenty of times do a search and you will find out as much info as you need to know. But no there arent any problems it bolts right up you will want to use your obd-0 injectors with the resistor box though.

*EDIT* Im not sure if you can use the obd-2 injectors or not?? I know you can use obd-1 injectors if you just take out the resistor box and hard wire it up without it I dont know if its the same for 0bd-2 though? Thats why I said use the obd-0 injectors and you wont have any problems then.

 

I have already installed the intake maniflod on my motor but I'm having an idle problem. It holds at 3000 rpm and doesn't come down. The ecu is flashing a code 10 which is the code for intake air temperature sensor. This sensor on the stock SI manifild is located near the master cylinder on the side of the manifold; however, on the 99 EX it is located inside the air intake tube that attaches to the throttle body. I have just relocated the wiring and installed the sensor into my intake tube. I am also using an integra throttle body from a 91 ls. I removed the vacume controlled portion from the throttle linkage and I'm beginning to wonder if this might be the cause of my idle problem
