Change the intake gaskets, found the CTS broken and changed it (didnt have code 15 before). Put the motor back together, ran smooth for about 10 seconds, then rough and shaky. Checked codes, got 15 and 43. Changed CTS and code 15 cleared. Finished setting the timing from having engine al apart, unplugged battery again for a few minutes. Plugged everything back up, code 15 is back and its running pretty rough.

HELP!!!

 

Ok, got code 15 to clear. Cant et rid of the 43. Tested voltage on the lead with the key on, engine off, it was only 3.6 volts. Tested resistance of KS, nothing. It read 1 the whole time. Where should I start??? Links to any helpful posts are appreciated too. Ive searched till im cross eyed!

 

These might help

 

Cool, what manual is that?!?

 

well crap, just read where there's two knock sensors on mine. ugh. Anybody know what size sockets to use?

 

yep there is one on the driver side on the block and one behind the passenger side head

I cant seem to remember what size they were tho but make sure you have something to catch the coolant when you remove the one from the block.

I use GM service manuals

 

can I get to the one in the rear without taking the intake off?

 

yes,lay down over the engine,pull off the dis cap,and lay the cluster of wires to the side. and reach in there with some channel locks,and fight with it till its done. it sucks.

 

Thanks. you wouldn't happen to know the socket size on those would you?
