i still need some advice on this one my car shutters badly when going into boost,and will sometimes shutter quickly when idling.i just put this motor in and ive pretty much checked everything i know how to its not arcing its got a good coil fer sure,the feul pump semes to work fine although i will put a guage on it soon,i was reading another post that said something about a map sensor,well i put a 94 engine in my 90 and used the old map,but my computer is not showing any code but 77 operator error.is it possible the newer map is a different ohm n did damage to my computer?if none of this sounds like anything to any of you i guess im gonna have to try another dis module.thanks
