A week ago the idle on my 95 Camaro suddenly became too high, and would stall if I wasn't accelerating, then wouldn't even start. I changed the Idle Control Sensor and it was fine. Yesterday, the same thing started again. I thought maybe it was the fuel pump, but it isn't, I used the fuel pressure tester on it. I am stumped and need some advice......

 

for the high idle check your vacuum hoses. and try replacing the fuel filter. im going threw the same sort of thing with my fuel system and i keep getting told to replace the filter.

 

is 95 obdI, or did the v6 have the goofy hybrid thing like the z had?
i would assume your car is throwing codes. Go get those figured out. You may have had an O2 fail and your car is trying to run SD, and most SD factory tunes are essentially "limp home" style tunes.

 

Thanks for the replies. I am replacing the upper intake manifold and throttle body, and like you said the fuel filter. I hope it isn't the fuel pump. When my parts come and I change them, I will see what happens next.

 

Have you had the codes checked? I would stop throwing money at it and start having some tests done.
