ok whats causing this
 

i have a friend with a 95 olds 88, it says lss on the side, but says its not supercharged (i havent looked under the hood yet).... anyway he said that it just dies on him, and it will do it at idle or when driving... he took it to a local shop and they pulled the codes, so here they are, and the def they gave for them:

P0321 Spark refrence lose
P0341 Cam crank error
P0740 TCC error
P1530 A/C head pressure switch open

the only code that i could find in the chilton manual was the P0341, i think that his pcm is bad, can anybody verify this... is there anything that i should check, should i check the ground...

Sounds like he has 3 distinct problems, and not a PCM problem.

Cam sensor or magnet
TCC solonoid
AC head pressure switch.

Will nailed it. Defiently not a PCM problem.

thanks
