Hey there. I have a few issues with getting my new engine to idle at about 750 rpms. The alternator was squealing/smoking, so I replaced it with a freshly rebuilt one (appears OEM) from Nate Crisman. The engine is a 2.3 with 2G Mas, 2G dejon pipe, and the stock 450's. FPR is from a 1G N/T A/T that is the highest flowing stock FPR I believe.
The stock throttle body was working before I put the car back together. Cleaned it out good before I installed with new gaskets. Vacuum lines on top are all hooked up and routed properly.
I replaced the tan top ISC with a black top off a parted out, formerly running 2G. It was bouncing between 1000 and 2000 before. Started it up again and it was at 3000! Turned the car off and grounded the idle switch connector near the firewall to the battery. Used link to ground the OBD pin as well and turned her back on. Started going right with the BISS screw and it bottomed out. RPM's only dropped to about 2500. FYI, I have 2G MAS and 450's selected on link, but no other adjustments had been made.
The only thing I can think of now is the TPS, which I have a replacement laying around. The throttle cable is adjusted and butterfly valve is properly closed and functioning. I have a N/T throttle body that I was planning on using later, so that is why I am using the old one.
The high idle could also be attributed to some vacuum line routing issues I am having. I have a 2G dejon pipe with a recirculation tube fitting, but no valve cover vent or charcoal canister nipples (got in way of radiator fan). Dejon says it is okay to vent the CC line to the ground. They also say it is okay to vent the stock intake tube line off the stock boost controller.
I was planning on running two catch cans. Here is the setup, but I don't know what to do with the line that would go into the intake to make the PCV system work properly.
Should I tee into the BOV recirc tube? Would capping that line ruin the loop of the PCV system? I appreciate all input. Thanks.
