with WOT (from a stop or at any speed) cuts rpms to an idle and will stall if pedal kept depressed. FPR i assume is good. checked with pressure test. new IAC, MAF, FUEL PUMP, fuel intake line,starter, battery, fuel filter, ect, brakebooster,TPS,plugs and wires, coil pack, an o2 sensor, and an injector.......... no vac leaks........idle is ok without maf plugged in a little rough, but not bad. just alot of black smoke, and 9 miles a gallon.....unplugged im getting 11 mpg and runs good with a little stumble when under 15 mph. but WOT is great without maf? and visce versa. im on the last straw. paid more for parts then i did for truck. thanks to all you knowledgable and insightful people. i'm open to all suggestions.:exp:
