Default Car stalling

I got my pcm back from pcmforless and put it in today.fired up the car and then it started to stall.Im 99% sure its not the tune.the only thing I did to the car while the pcm was out was swap out the old fuel injectors for some 36 lb SVO's.The injectors are used so do you guys think that the injectors are the problem? Sould I swap in the old injectors to see what happens??Can I run stock fuel injectors while the pcm is tuned to run 36lb SVO'S?
Can clogged injectors cause this?

Is is driveable at all? The PCM has to go through a relearning process before it will be happy with the new settings. Just a thought.

Well since they were used the only thing I can think of is are you sure they are really svo 36s? If yes I guess they could be clogged, but for it to totally die it would have to be pretty bad.

Injectors are one thing you absolutely have to tune for though, so no DO NOT run your stock ones on a tune for svo 36s, if you do that it will be so lean it could cause serious damage.

swap back the 36 lb svo's today and it started and ran for about 5 minutes.Is there anything I could have done wrong when I changed the injectors???

this is what I did when I changed the injectors.
1.disconnect battery
2.Open gas cap to release fuel pressure.
3.remove clips from fuel injectors.
4.remove 4 bolts from fuel rail
5.removed fuel rail just enough to get to all the injectors
6.remove old fuel injectors and put in new/used svo's
7.put fuel rail back,put clips back into place

anybody see anything wrong???

Contact the person that did your tune cause I bet it is in there. When my pcm went out it would start for like 3-5 secs then die.

Got an e-mail from bryan at pcmforless and he said that my problem sounds like a VATS issue!
Has anybody else had a problem with VATS after getting your PCM tuned??
