im asuming its the TPS but just to make sure im gonna see what you guys think. well it ildes fine for a while but when it gets really wamred up it starts to idle really lumpy likes it has a miss or something, anybody know?

 

flux capacitor or muffler bearings.

 

SOB.. better get me some of those, ok but seriously. there are such things as muffler bearings tho so... that joke doesnt really work

 

mazda 929 has muffler bearings

 

so...

 

if you have verified in fact that the timing is set correctly, and it does in fact idle smoothly prior to warm up, then becomes eratic, its the tps sensor.

 

by the way, wtf is a muffler bearing in a rx7 ? LOL

 

no there arent any, in the rx7, I know the 929 has them, and the JC cosmo has them too I believe
