My KA is being a bitch, in every gear when i hit 5 grand it won't go any further and starts choking and spiting at me, its almost like i have a rev limiter at 5 grand, i tried changing the plugs and that didn't do anything apart from that that car runs and idle's fine but if anybody has any idea about what that might be please let me know, thanks

 

maf dude....clean it or get a new one

 

make sure you dont have it in backwards too...dont ask

 

either that or check your crank angle timing.

 

ight all do that thanks guys i'll let ya know what happens

 

is there anything special i should use to clean my maf?

 

when was the last time you changed your fuel filter? If a maf goes bad, it wont rev past 2k. I'd rule out the maf and look for fuel related issues.

 

^ yea like it's hitting a "fuel cut" get a 300zx one

 

i didnt even think of that

 

Might as well get a new maf on there, but I think there is a cleaning procedure you can do with some carb/brake cleaner that could possible save it. You would be surprised how many sensors can trigger a "rev limiter".

Confirm base timing, make sure all plugs, wires, cap , rotor, and disty/coil are up to snuff, get the new maf, reset ecu, make sure there are no codes and you should be set!
