Help needed

Hi
I have a problem with my S13. Looses power suddenly. Feels flat before boost. Takes forever to rev up.
I haved replaced injectors,spark plugs, FPR, CAS, slightly better but not right. Did fit a cone filter as well. Please help. Goes very well when its right!!

I experienced a similar problem to you until I did a major service and replaced all my filters, turned out my fuel filter was buggered. That and a nice tune-up sorted me out 😀

I'm sure one of the more mechanically inclined guys will be able to give you a better answer though 😉

nope, sounds like youre screwed 😕
