Ok somethings wrong now. only like 60 miles and Im down around 1/4 a tank 240miles to the tank give or take thats seems really low....

Thats only... 10MPG... I haven't changed anything sept for starting to use Over Drive. I thought over drive is to HELP gas mileage???? I'm going to do a tune up tomorrow. AFTER I fix my Z lol

 

could be a faulty fuel level sender.

 

Or that

 

Ok now my truck seems to be hesitating around turns... and I have a full tank of gas. Man this truck likes to confuse me!

 

Stupid question??????? But important... The o/d are you turning it off when your thinking your turning it on ? Drops down a gear and raises the rpms = lower gas milage

 

next time your by vatozone parts stores or walmart, grab a big bottle of lucas fuel injector cleaner and dump it all in right before you do a fill up.

 

The O/D is on teh gear select lever, its not an electronic overdrive. But yes it does drops the RPM.

And I think I will Hoov, I usually done but I haven't for awhile

 

Great my last vehicle is pretty much about out of commission. Its leaking oil like a sive out the rear main and a bunch of coolant leaks have started to crop up. ugh I don't wanna pull the trans out in winter time to fix a leaky rear main... man V8s suck only 100K miles on it and its giving me problems now. but my Z had like 170 and didn't even burn oil.
I miss my 2+2...
