We set the timing at about 8 degrees. The fuel pressure is set at 44psi. This thing is pulling 12 inchs of vaccumn at idle and even my own 388 pulls 16 inchs at idle. I change the plugs on it switched out the ignition coil. I've reset the valves incase they were not set properly even though its a crate motor and you should have to. I played around with the PROM, and when i try to give it more fuel in the VE tables, it just runs terrible. The plug readings are jet white, which means its running way too lean, but it doesn't like to run any richer than it is now. The car is extremely jerky fuel if added to it in the PROM. What other suggestions to run on the checklist to get this thing going properly before nationals?

 

what else have you tried?

 

Now i'm going back to the basics and checking to make sure the firing order is correct. I assummed that Third Gen Resource would atleast have that correct but then again assumptions often lead to something going wrong. Thats next on the check list.

 

I take it you have already utilized some sort of scan tool?

 

running way lean....check for vacuum leak...check all areas..

try spraying some starting fluid in different areas and see if the RPM increases...that would be a tell tale sign.

 

i agree...the motor has enough fuel or it wouldnt run crappy when more added..that and the fact u only have 12 inches of vacuum, id say that u have a vaccum leak..and my buddy tjrh522
is dead nuts in the way to check for it..

 

no vacuum leaks, i sprayed all around the intake and nothing happens.

 

Did you check all the vaccum lines? Some of them are hidden well.

yep and replaced all of the vaccumn lines to make sure the old ones weren't at fault.

 

Your "sig" had nothing about the cam specs. If the LBA is much less than 112 or duration near 230, the vacuum will be very low.

 

cam is 208/221 LSA 112

 

have you checked to make sure you don't have vacuum runnning straight to the EGR? Is the EGR stuck open some?

 

There is no EGR on the Stealth Ram.
