[DML] Help me!!!!!!!

["painterdave72" <painterdave72@xxxxxxxxx>]

Hey all please give me some insight to this freaking problem.. My car still does not 
idle smoothly... or rather the engine vibrates at idle..I ahve just installed all new fuel 
injectors and the car runs and accelerates excellently... I have done a 
commpression test on the cylinders and they all have great pressure.. I have tested 
the fuel pressure and it is within parameters and holds pressure fine.. Where i have 
the c02 screw set now is alittle richer from wehre the car dies when u lean it out.. 
that is why i think it shudders at idle,, but if i make it any richer the car does the 
annoying backfire thing out the exhaust.. its now excatly backfireing though its just 
like when u drift down a hill on a motorcyle with straight pipes and let off the gas the 
rumbleing in the exhaust.. i do have a free flow exhaust on my car with no cat 
convertor just straight headers to the muffler.. some mechanics i have talked to 
seem to think it is a result of the exhaust but some people such as John Hervey 
think it is still not right.. I dont think the engine should vibrate at idle either.. cause 
when u give it some gas it stops right away..if i do richen it up till the frequency 
valve shuts off it idles much better but is way to rich and does the thing in the 
muffler.. i am so tired of messing with this.. the car runs greatly except for this.. i do 
have a rebuilt warm up regulator also.. and every other sensor on the motor is new 
say for the actual fuel dist and the accumulator.. and the idle speed motor.. Any 
help?? please?? Thanks..Dave..Vin.. 15275...
