When giving slight throttle car "feels like" it cuts the fuel for a split second. I "think" it also happens on slight bumps and slight hills. Definitely has a spot when barely giving throttle, which is on takeoff and cruising in gear.
DW pump. Radeon rail and gauge. Pump and tank inspected/ rebuilt and seem good. 100% clean sponge and tank.
FP is 50-60 psi at the rail -good
When I pull FPR hose I get approx. 10 more psi.-correct
Not in tune. Tuner saw no issues software related. The issue wasn't present during tune as we were not at low throttle of course.
replaced all stock injectors.
Car never codes except as learning occurs will throw P0420 because I'm cat less with all stock emissions on at the moment. Nvidia one piece down. Stock 02's connected and read ok.
No boost leaks found. I hit 30psi peak for a split second then taper down to low 20's.
93 Sonoco always.
Replaced all relays with no change.
The interwebs have me thinking to look more into ASC. I plan on turning off 1 press -testing, the turning off long press...
2 odd things this car has. No idea if related.
1. I show -2 throttle position and at WOT I get 98 on the AP.
2. The car has a half second before it responds to me pressing gas pedal.
I'm really stumped. Any advice is appreciated.
Just ordered Tatrix cable, evoscan, etc to start figuring out...
