Any codes? How old is the FRPS?

 

[hotcobra03]

Fuel filter and coils will cause this and not give any codes

water down a spark plug hole will also cause this w no codes - - chased it for a minute before finding.

Not sure on this. I went to amirilo Texas and bought car 2-1/2yrs ago. Its sits mostly.

I will try fuel filter. It will run up to about 2500 if you baby it. But you stab it and wow it chokes

Check the plugs. Datalog looking at fuel pressure, fuel pump duty cycle, and voltage.

 

[Torched 03 Vert]

Ok

Sounds like a fuel pump issue to me. Interested to see what it turns out to be

Mine did this when the FRPS failed. It never even threw a code. Stab it and bam, she choked. Hopefully you can datalog.

What intake does it have? The newer JLT CAI causes the MAF wires to bend to tight and rub. It will actually break the wires inside the insulation and cause problems. Happened on my brothers car. We cut off the MAF connector, soldered on a new one, clocked the intake the best we could to stop rubbing.

Has the same symptoms. Car would idle fine, try to drive it and would pop, backfire and everything else like it was flooded.

Possible the IC froze and you got water in the intake manifold? Seen that once.
