Ive finally got all the check engine lights off my b18c1 swap. Im running a p28. After all the cels were finally taken care of I still have a high idle. After running hard sometimes it even stays at around 2k. Could my throttle cable need some adjustment. (it would be great if it were only that simple). I plugged in an old p75 just to see if maybe a different computer would idle it differenty. Nope... they both idled at 1500 rpms. So what causes this??? No CELS right now...

thanks

check throttle cable slack. adjust tps, or tb idle screw

 

ok..I can do 2 of the 3.. how do I adjust the tps???

 

my friend had the same problem on his gsr wen he did a swap. is it the stock gsr manifold? cause on his it turned out he was suckin a piece of the intake gasket in where the secondary butterfly is located.
