I replaced my fuel filter, and discovered a pretty bad overheat issue on the way back from taking some stuff to my storage unit. replaced the thermostat and added a gallon of coolant (it's still low) so going to add more tomorrow AM.

My dad has yet to fill his 08 F150. $120 doesn't even do it.
As for me. Drove a thought alot! Tried to pinpoint my "no *****" problem. And tried recreating it over and over. I can't, I just either get it running great or stumble and fall on its face. Never the same outcome. Used to be bad on hills, now great. Had o drive like a granny to get anywhere, now It depends on how it feels. It really irritating me because it usually happens when I need the power. I'm afraid to go on the highway. Got the codes read and I have O2 heater circuit bank 1 sensor 2, and good ole' random misfire. Chris mentioned TPS, but can that be intermittent? Like I have full throttle range sometimes but then others I give it half and it SLOWLY creeps up to about 2000 rpm and then jumps instantly to about 3000 and takes off.
I'm lost, but I'm glad my job is kinda close and no highways.

A misfire will put raw fuel into the catalytic converter. This in turn will tell the rear O2 sensor that your cat is clogged.
Try replacing the rear Sensor and doing a tune up. Hopefully the cat is ok
Today I didn't doing anything to the Blazer but I did notice an open vacuum line and I can't find its home. I have a PAUL 0288 is coming by tomorrow to do a comparison. I will no doubt be replacing some crusty looking vacuum lines though.

the cat was done. it was chocking off the exhaust, causing the truck to fall on it's face. drilled a hole before the cat, got over 10lbs of back pressure. truck ran 1000% better after that, but it's still not perfect.
yet.

if i still had my '91 3/4 ton chevy i wouldnt be able to fill it up, had a single tank that held about 40 gallons, from empty it would be over $100 to fill, the 20 gallon tank in the blazer and ranger is bad enough when they get low.

don't feel bad. it costs me around $170 to fill my 'Burb. really sucked a couple of years ago when diesel sat around the $1.40/L mark.
but if i stop for fuel, i always fill it up. can't see the point in putting in just a splash here & there.

at least your diesel burb will run on veggie oil. some places are dying to get rid of that stuff.
someone around here's got a CUCV blazer with the 6.2 Diesel that I wish i had the 2 grand for.

I helped a friend replace a fried encoded motor in his 2000 Bravada last night. It was only part of the problem, but a ste in the right direction. For some reason, my scan toll cannot see the front or rear prop shaft speeds. It can command the transfer case to lock up and that does definitely work. Very weird. He is going to ohm out the sensors and see what the output is when you spin each driveshaft. If that all checks out, then the ttfn is likely also bad.
