Won't Idle???

[Stroker396]

A little advice from some of you more experinced tuner guy would be a great help.

I stroked the motot to 396 and put in a CC503 to a 97LT1

I reveiwed several .lt1 files (thanks to BadZ28) that had big cams and they were almost identical. However my car does not want to idle on it's own either with the stock programming or the modifications.

It seems to be leaning out and stalling at low RPMs it also knocks and has multiple engine misfires P0300

The scanner is thelling me that Bank one is being leaned out 4+% and Bank 2 is being incresed 25% in the LTLF

Any advice???

Ok I got it idleing now,

I would drive it but it has multiple engine misfires happening.

I am changing the plug wires (found one bad one) then will see what happens.

Any other possible causes for misfires? let me guess Opti

Why did you review files that had big cams when the cc503 is a baby cam?
