after reading everything in this thread, i too am thinkin the o2 sensor is the place to start, was actually what popped in my head after reading the thread subject. do as he said before and unplu the pre-cat o2 sensor and see what happens.
but yes the plenum also kills mpg pretty good. i was gettin like 9-10 mpg city and after full tune up with plenum and o2 sensor changed, im now at 12.5-13mpg city.

i check the milage by setting the odometer to zero every time i fill up also by the sensor thing that says how many miles per gallon you get. to today i had to go get something about 40 mile from my house i was driving for about 20 miles on the freeway and all of a sudden i started to get 28 miles per gallon on the free way then i got 8 mpg on the streets. it was the first time i got that good of mpgs. but i dont no whats going on with this truck. i will check the oil in the morning.

man i feel like calling a taxi, it might be cheaper to have him drive me around then continue to drive this truck. I only got 61000 miles on it..... this sucks!!! im going to try and take the o2 sensor off in the morning also what should i use to take it off, cause i know it will be hard after being heated up and being on their for the past 13 years. any suggestions???
