- it is easier to fix and understand than "her"
test the vacuum under load and at idle, air meter for proper function, intake for air leaks, timing, rail pressure at speed and temperature sender for the eec.
without a high high idle complaint its hard to see the intake leaking but its one of those things with blown out insulators....that and burned valves. with no popping complaint those seem unlikely. but between the tps and maf you can have load issues.
i cant believe you gutted the cat. i mean take the fawkers off and drive it.....see what it does....based on those results and how easy it i to see thru....determines whether you want to gut it....and when you gut it you need to tune it. the o2 sensors will never work right again when you cool off the exhaust that much. so its compounding the problems even if it was plugged.
k&n filter in the right hands i a great tool for building performance, in the average guys hands is a potential for disaster.
this is probably a case of the k&n fawking you...... you boogered up the air meter....and the truck trying to deal with that limited out and burned up a few cylinders.......judging by the spark plug report.
