I have a d15b1 boosted ek I bought . " its has aftermarket ECU , Injectures . for some reason , my rpm are really high like about 2k than bouces back down to 1k & repeatedly keeps doing it , & its kills my motor . also therss white/blueish smoke don't know what it can be . PlEASE HELP ! THANKYOU

 

bouncing idle can be as simple as a iacv needs to be cleaned

blue smoke is bad means your burning oil do a compression test, I wouldnt trust whatever aftermarket computer was put in there you should take it to a tuner once the other issues are resolved and verify its tuned properly
