Terrible bogging, no codes*

[The Radium King]

there's no code for low fuel pressure, but there is if the ecu can't hit the proper air/fuel mix. now, if it is only happening at high load then ecu isn't monitoring afr, so may be a fuel pressure thing that the ecu isn't detecting - reduced fuel pressure/flow doesn't become a problem until engine is demanding more fuel - crud in filter?

ecu reset is just disconnect battery for a bit.

I'm replacing the filter tonight so we'll see.

When you say bog, is it cutting off quickly or just slowly dying? If the former, I would be looking at electrical. A bad spark plug wire or broken plug issue will only manifest under load in many circumstances.

It cuts off quickly and all cylinders are effected (or seem to be). It cuts in and out rapidly but you don't get that failed coil sound. More of a struggling to run coughing sound. Sounds like a carb'ed car with a really bad mixture. If it were electrical I think I'd get a misfire code.

Welp. Filter didn't fix it.
