After four years of my car sitting in my drive way i thought it was time to get it back on the road. I stopped driving it because it stopped running right, it dumps so much fuel it looks like a big rig. I have replace o2 sensors and tried different MAF sensor but no change. I noticed that theres no vacuum at an idle so started to look for an leak even pulled the intake off to check the gaskets but all looks good. Did a compression check on the left bank all around 150psi will check the other side on saturday. The car wont idle unless your foots on the throttle a little bit but will soon flood its self out. Before i parked it i replace the opti it has like 3 miles on it but no change. My car has a355 with 9.1 comp p600b with 12lbs pully #42 svo injectors lt4 intake crane cam auto msd 6a with coil hooker sumper comp headers no mufflers just an x pipe with side outlets 255LPH intank pump with a inline booster pump ngk tr6 plugs and taylor wires no tunning done yet but drove the car for 7 mounths with no tunning. Any opinon would be great. im getting ready to shoot this thing

 

One or more stuck injectors, or a ruputred fuel pressure regulator. Spark plugs will likely tell you the story on that. I wouldnt even attempt to fire it until i was sure i had a handle on the problem, it doesnt take alot of fuel to fubar the ring seal good.

 

Thanks for the info but i replace the intake gasket and it runs good now

 

I'm sure it runs real good with those 42# injectors and no tuning.
