I just did a spfi swap on my 86 hatch, runs great except for when i stop at a red light or stop sign ect... the rpms rise to about 2800 rpms and holds till i take off. and then runs fine and when i stop same thing. its very frusterating cuz i cant afford it to be burning gas like that. and i dont know much bout spfi, ive checked: for vaccum leaks there are none, timing is good, and idk what to do
Thanks
