Its still cutting out when its hot , you give it gas and it starts slowing down but was still able to work through it to get home. Ran fine that morning. INT is all over the place Bl is low , replaced cam sensor, coil, ing module, plugs , fuel filter, checked the grounds so what the heck is going on? Could it be a bad fuel pump going bad? God just when you think you have it beat it gets back at you again.
 
INT bouncing is normal, low blm would mean it's pulling fuel, not indicative of a pump problem...look at MAF sensor........
 
I did try that before no differenace when,I unhooked the cam sensor it ran fine so replaced it and still doing it but seems only when its hot outside when its cool it runs great, this all started after blowing my HG's not sure if I hooked some thing up wrong thought grounds but they are tight.
 
How close is your downpipe to the fuel return where it usually is close to the frame? You running a fp guage you can monitor while driving?
 
You CAN tap the maf while its idling and often times a bad maf will cause it to stumle/cutout when tapped on.
 
Did the tap test nothing, also pulled battery ground and cleaned it, and lower ground on the back of the head. Drove it ran fine got hot will need to drive it for a while to know for sure.
