ok guys hopefully u can help me out i just got done swapping a b16 first gen into my 91 teg. The problem that i am having is that the motor is ideling at about 4k rpms. there are no codes and i have messed with pretty much everything to try to get it down but no luck. im thinking maybe a vaccuum leak or something but havent spotted anything yet. im also having a problem with my header it turns bright red like its going to melt. its a megan i dont know if these problems are related but if u guys got any ideas let me know

 

i think i got the idle figured out

 

probably a vacuum leak or your map sensor is messed up, they always break in the 2nd gen integra's

when my map sensor went out my old car was idling at 3k all the time untill I extended the wire to plug it into an obd1 TB map sensor on the throttle body its self

 

figured it out thanks

 

the header glowing red is either running rich or your timing is off(engine)

 

o i see that explains it thanks
