I've had the blower on the new motor for about 1000 miles now, and have changed the belt many of times before, I was doing the routine swap yesterday and took the cutoff off because I was going to go for a little cruise w/friends.......

I started the car, pulled out of the driveway and right away I noticed something wasn't right, the car seemed to be struggling w/acceleration, misfiring, etc, the usual misfire sounds from an open exhaust.....

When I went to get a new oil filter today I plugged in the scanner at the autozone and it showed (2) P1336 misfire codes....

Any ideas to why it would decide to throw these all of a sudden?

P1336 is CKP out of sync.
Some how the PCM has lost the sync or a bad PCM or cam sensor?
Put it on a Tech-II (or others with this feature) & do the crankshaft variation relearn & see if that cures it.

BIGBOS

With the regular OBD2 scanner it was reading as a misfire code and not a crank position code, but after reading, I guess this is what its related too, I'll have my tuner fix it w/LS1 edit most likely, car is going in for dyno tuning soon

Would it help to keep starting the car to see if it "relearns" or does it need to be done w/the tech II

what all is involved when you swapped that belt bosman?

there are a few things you could have messed up by accident even at the front of the motor that would effect the cam sensor.

give me an idea of what you remove/mess with to swap the belt and i'll tell you if i see any possibilities

oh and is it backfiring or no

BIGBOS

yes, its backfiring.......

And the only thing involved is putting the belt back on the crank cog pulley......taking the blower off.......I can't see how that would mess w/the sensors either......

ok, you have a spark issue then it sounds like.

when you take the blower off..do you mess with ANY ignition stuff at all?

particularly do you remove the harness for the coil packs or unplug anything related to the packs, the harness, or the cam sensor plug that is on the front of the passenger side fuel rail??

you need to not be driving that car man if it is backfiring..you could detonate that thing..

gotta run be back in a bit will say more

BIGBOS

Its not backfiring bad, its making the usual dropping cylinders noise under acceleration, I'm sure its the plugs, I won't be driving it again till around may.......

how is it at idle then? yah change the plugs for starters, but basically when you have a problem that starts right after you do something you need to go back and look at everything you did that could have caused a problem which is why i'm asking these questions. plugs wouldn't just all of a sudden go bad especially since the car wasn't running when you were chanign that belt.

just go through EVERYTHING ignition related and make sure its all back together properly.

get it on a scanner and see wherre the misfires are coming from..that will narrow your search..if they are all on one side of the motor then you know to concentrate your efforts there.

BIGBOS

Car idles fine, I didn't mess w/ANYTHING ignition related...

I'll change the plugs today/tomorrow and see how it does after that....

ok let me knkow

It needs to be done with a Tech-II,they dont relearn it on their own.

BIGBOS

I see, will changing the plugs possibly solve the problem or is it all in the PCM here?

Put all new fresh plugs in today, didnt solve the problem, looks like I'll have to wait until I get into the shop for them to do a tech 2 relearn with it...

BIGBOS

Up to the top, can LS1edit take care of this problem?

BIGBOS

I tried running the Tech II on it, and it kept asking for me to go WOT then release at fuel cutoff, I kept doing this, and it got me no where, it never ended....

So I don't know what to do now...
