2003 Dodge Dakota 3.9 PO351, backfire low power

Good fuel pressure. Distributor Sync set to 0
Attached is the cam and Crank current waveform.
Crankshaft position sensor was replaced due to customer damage of old crank sensor when customer installed their own clutch

Problem started after clutch installation

Po351 keeps coming back on when you got wide open throttle every single time

Also replaced the ignition coil attached is screen shot of ign primary waveform measured at control,side of the ign coil

And the Cam and Crank signal waveform. Yellow channel is Crk green Channel is Cam

This vehicle has absolutely no power when you throttle

Ign wires are in right location per firing order.

Back pressure test doesn’t show clogged exhaust either. O2 sensors respond to rich and lean induced conditions too.

Any input would be appreciated

I’m not good at looking at ignition waveforms but the firing looks kinda funny. But have you checked how far of a gap the spark can jump with a spark tester while running?? Could be weak spark

Spark is plenty strong. Camera just caught at odd time when engine was being shut off. Otherwise raster pattern looks good

Have you gotten a known good cam crank relationship to compare to? Have you checked what the o2 sensors do at w.o.t

Yep. Someone here on the forum had a known good waveform on another post. My waveform is same as theirs.

O2 sensors are fully responsive. And if I lean or Rich the mixture they respond as well
