ok well i have two supras both 89 one turbo one n/a the n/a car is having idle problems it idles better now that i adjusted the tps but now im having a problem when im getting on it...it feels laggy like its going really slow and it skips like its not either getting enough fuel or its arking on something idfk ne help would be apreciated

 

check to see if its throwing any codes

 

yea any codes being thrown???

AFM plugged in?? fuel filter could be clogged

new plugs maybe? check the gap on the plugs?

 

Are you sure that the car isn't getting any fuel? Is the timing off perhaps? Check the CPS...and like reaper said, check the afm...sometimes those cables can get jacked up!


EDIT: scratch that, N/A do have CPS's so, don't bother checking for it! But, instead just run over your wiring and make sure everything is ok.
