OK, so let me start by a quick truck history: It sat for 8 years, guy couldn't get it to run. I buy it and find the HP pump is stuck and wont rotate. Couple whacks with a screw driver and it spit and sputtered fuel out, hooked it up and she fired right up. Went ahead and did that following:
-Removed fuel tank, scrubbed and cleaned
-New intank pump and sending unit
-New HP Pump
-New fuel filters
Took it down and she barely passed California smog by a 1 digit margin (BTW, it always had a noticeable miss even when getting smogged). 2 days later the truck starts running noticeably worse and worse (drove a couple miles a day to keep it going, was not a daily driver) and then to the point one day the truck would shutter and barely run. So, since smog guy said my cat was almost toast, I went ahead and done the following:
-New catalytic converter and exhaust system
-New o2 sensor
-New cap, rotor, coil, plugs and wires
-New TPS, MAP, EGR sensor
-Removed and cleaned IAT sensor
-reset timing to 10* (I did it correctly)
-New fuel pressure regulator since old one was leaking into vacuum.
Truck then ran worse than ever, chugging blackish smoke and got a best MPG of 8.02. Found the regulator was defective and replaced again (no more issues) and now its up to 12.64 mpg (101.2 miles, used 8.009 gallons). Shifts great, runs super smooth, has no power for a v6 whatsoever, I usually drive around in 3rd because it just cant pull in 4th with converter locked up. Please help because I am about to sell it. I wont have crappy fuel mileage and no power. Please, any help is appreciated.
