Hi there, mostly browse/research on here but this issue has gotten the best of me.
I just got the a 91 Talon AWD together and back on the road and am experiencing a difficult to determine fuel cut at mid-high rpm boost.
Stock motor has new gates belts, timing components, water pump, fluidyne crank pulley, 150 psi compression across.
Setup
255 Re-wired
AFPR
Precision 880s, stock rail
Stock fuel lines
Fuel filter-looks new from outside, not sure of replacement date
(drained system& flushed w/ new fuel, filter flowed well)
BLT to 30 psi, no real leaks, tb seals SLIGHTLY but have never caused issue.
Emissions deleted
Stock 1G ignition and timing, base -5deg
new wires
10k km plugs, look good
stock smic, hard upper piping, stock bov. hks elbow, stock IM
small 16G on gate pressure (12-13 psi)
3" turboback w/cat. FP manifold
Zeitronix WB02, Boost Sensor
Dsmlink V2
02's are 10.9-11.4 until 7k rpm when cut hits. Only idea I have is that maybe stock maf, which is reading 1900-2000Hz is being overran? Breakup happens mostly in 3rd gear, CEL blinks, Knock counts (3-4 deg).
Car is plenty powerful and runs well overall. Idles steady ay 900-950 but will randomly idle at 2000 rpm after hard run for a few minutes until it cools down, then idles normal. This cut has got to go, hoping to hit upper 12's with this setup in a few days, well, at 18 psi
Thoughts appreciated.
Thanks
