hello. i swapped a b16a in my 91 si. i got it to start but it sounds like **** when idleing and i cant rev past 3000 rpms. there are also 2 plugs from my harness that i do not kno where they go, it looks like they would go under my intake manifold but i cant find ne where to plug them in. does ne one kno a site or have like a diagram of where all the plugs for the harness go? maybe they r the reason my car wont rev past 3grand? can someone please help me this is my first swap n ive been without a car for TOO long n want to get her out on the road.

 

Check and make sure you didn't mix up the TPS and MAP sensor plugs. They are both 3 wire plugs with the same plug in. One plugs in to the back of the throttle body and the other depending on your model year plugs into the MAP on the throttle body top or the firewall mounted MAP.

 

yeah check that and also make sure that your tps works correctly

 

yeah im pretty sure its the map sensor since theres not one on my throttle body n theres not one mounted on my firewall which sucks ***. lol but thanks for the help guys. im gonna call hmotors to see whatsup with that.
