sometimes the car runs good but then out of no were the car cuts and wont go over 2g rpms in all gears and i have no clue..................please help

 

Sounds like limp mode to me.

 

what should i do?????? how can i fix this...........

 

When this happens. is there a CEL being thrown? If so, you're in limp mode and the ECU is cutting power for some reason..... get our engine codes and diagnose the problem

 

what kind of car are we talking about here?

 

exactly

 

1986 Rx7 Gxl

 

There's no fuel cut in that car.

What mods have been done to it and what has been maintained recently? Are the plugs old? Hows the compression? Have you changed you fuel filter this year?

Give us some more info.

 

Its was the TPS i cleaned it up and ajusted it
