so my car has been apart for 2 months ( had the heads our getting ported by a local shop of mine) i finally got it back togther yesterday around noon and it idles great runns good has plenty of power but every now and then it has a stumble to it in the lower RPMs i was thinking it was bad gas cause it sat for so long.

then I started thinking it could be the stock injectors ( i know i need larger ones) or it could be the Stock Tune!!! i have not sprayed it yet with the new set up cause i dont want anything bad to happen. tonight or tommorow i will check all vaccum lines and harness plugs again just to make sure but do you guys have any ideas?

 

nothing? no ideas? come on guys

 

could be other probs...stutters and misses dont always come from fuel issues! what exactly is it doing??
