i ahve a 97 gsr motor has after market intake ,70mm thrtle body, aem fuel rail,310 rs injectors and a few other things. I cant seem to get it to idle right it drops down to like 500 rpms or lower than shoots up like 1500 to 2000rpm it will run like that for a while then drop down again. any ideas or sugestions would be great

 

what else is done that requires a 70mm TB and 310 injectors, did you get a tune? Got any aftermarket cams, header, headwork, etc?

 

it had a turbo on it but the kid burned up a piston. then took it to a local shop and had a new engine built. I was told it had stage 3 cams it has a full apexi exhst (header back) with a cat. I was also told it has new pistons and rods set up for nos. I am going to take off the valve cover tomorrow and see what kind of cams are in it. plus I pulled out the RC 310 inject and put some stock ones in. it runs alot better but still does the idle thing. Plus I changed the Iacv and that didnt help.

 

...is the car tuned?

and lol at "engine ready for NOSSSS"

 

no I dont think it has been tuned it is the stock ecu p72. Iam trying to hold off on changing the ecu over to obd1 and then get like a hondata unit.
