Ok well some kid bought my turbo kit..for more than i payed NEW..so i couldnt say no..anyways I swapped out all the parts. and put a stock gsr exhuast manifold on my car..and i just put in his stock gsr ecu just to get home. I turn the car on it was idling at like 4 ,000...i checked no vacuim leaks that i know of i always put his stock 240cc injectors back in and wired them back up i previously had dsmn 390s and resistor box. The o2 sensor is now put back in aswell..now it putts and runs like *** and wehn i stop at a lite it dies and i have to push th egas to keep it reving..now im sure running the gsr ecu has to do with this..but any ideas why its idling so high..and the stalling?....


TIA! ps this is on a stock LS obd1

 

Were you running a "missing link" or screwed with the IACV at all?

 

I was tuned on crome pro before and nope i didnt touch any sensors ...its odd so im stumped i haven;t really looked into it with great detail yet but just looking for thoughts.
