im in need of help please any 1 please help heres my symptoms
it seams to run great till is gets warm then starts to sound like a piece of $hit subaru.
mis fire ? is my guess been working three days stright on it i put new motor in it and now i have this prob.
motor is fully built by me ross pistons manley rods iggly griddel acl race bearings ported head bc titanium evo 8 rockers bc 280 cams aem cam gears, gtx 30r turbo trial wastegate greedy bov dsm v3 gm maf with ecmlink direct cable .going to sd ASAP
with that said i already had everything up in going with old stock motor only thing that is new to set up or underhood is bc 280 cams and knock sensor
what i have tested/ swaped parts since problem
new ngk plugs gaped.028-30 made sure timming right on tbelt two times made sure ignition timing is 5 tdc,did comp test 170+ on all cyl made sure CAS is right not 180 off swap inject risster, killed injectors in dsmlink one by one seams like #1 no diff on or off when i pull plugs cyc1 its spraks when pulled but no drop in engine performance , vac psi good at over 10-15 psi at idle. swamped injector from cyc1 to cyl2 cly1 still no diff when cut.
this seams like a electric problem when its cold it seams to run purfect WTF im stumped anything to look for in dsmlink?
im leaning to bad ecu?
i have also read bad lifters? i have new topline 3g lifters
i can up load a log on v3 too
