Phantom of the Opera
I have a stepson's 3/4 Dodge van 318 DPFI Holley system stamped on the t-body....
fp is 32-34 and changes to 40 under load, rises to 50 if I pinch the return line....changed the crank postion sensor because engine tended to die at idle, restarted almost immediately....so it's new...idle is only 10" of vac....but closer to 18-23 at running high idle, no load....MAP varies enough to make sense....so does TPS, it tends to backfire too....
but not regularly....the injectors sound normal....
and pass a leakdown, holds 32 psi for some minits with out falling any....
going for plugs/wires now, nothing else makes any sense....misfires at idle and hates the gas under load....bogs and backfires like crazy...
I can't find a CAM position sensor, it maybe batch fire....uses a stock looking dizzy in back cap and all....I presume the dizzy just does index work on the spark....
same thing mine would be IF I did a crank position sender instead of the one in the HEI....
what is your experience???
thanks...GENE
