my drag is surging help

**Wild Bill** · 05-15-2023, 05:56 PM

I have a svs Drag that was working fine last time until i tried to plane and it wouldn't. I omed the stator and trigger and they looked fine but the purple trigger wires were suspect so i repaired them. I went out today and when i tried to plane off it surged like crazy. I have good fuel pressure while this is going on. I put a new stater on last year and it ran great until now. Any ideas?

Sell it to me and your problems will go away!

Did you check the vacuum lines to the pressure reg and to the ecu? If you get some condensation pooling in the lowest spot in the ecu map sensor line it will cause inaccurate vacuum reading and run rich. Also fuel residue clogs those lines (and fittings on the svs) up.
