I have a '95 Camaro Z28 with a 6-speed manual transmission. Whenever the RPMs are in the range of4000-5500 in 2nd and 3rd gears, the engine cuts out. It doesn't die, but you can feel the hesitation. I was thinking it would be an ignition/spark problem, but I didn't know why it wasn't occurring in 1st gear too. I thought it might be a problem with 2nd and 3rd gear in the transmission, some slippage maybe. I thought Ishould test 4th gear to see if it cuts out, but by the time I hit 5500 RPM in 4th gear, but there aren't many good straight roads around me to do that test Any ideas?

 

could be detecting knock and retarding the timing. mine is doing the same thingright now. its not knock but it thinks it is? dont know whats going on.

 

Are you getting any SES lights at all?

 

If you guys are having trouble with false knock get an LT4 knock module.

 

it's must less sensative to false knock.
*grumbles at forum*

 

no SES light, i did get the LT4 sensor and i had this problem, i put the lt1 back in and nothing changed. im thinking maybe i got a fake or faulty one?

 

i just though about it, do you replace the pcm sensor or the one in the block? i did the pcm

 

The actual sensor in the block is exactly the same, so you replace the one in the PCM. It should be GM part number 16214681
