Not diesel but need help...

Ok I have a 95 f150 with the 5.8 351W... its starting to get HORRIBLE mileage... don't have any hard numbers yet but I drive the same route and its burning almost twice as much fuel... there is this "ticking" noise coming from the enging bay... sounds like electric arcing... the plug wires (not sure about plugs) changed 12, 000 ago... the truck sounds like it is on rumble strips when between 40-45mph and 63-70mph... just wanna get some opinions on this before I go out and mess with it... its -3 outside and my garage isn't heated...

And thanks in advance for any help!!!

I'd post it in the Gassers forum, but I'd bet on some kind of ignition issue. I'm fighting a miss on a 460 truck right now. I'd go ahead and do cap, rotor, plugs, and wires. It isn't hard to burn a plug wire on an exhaust manifold.

I was averaging 8 mpg on my 95 f150 with 5.8 when I pulled the engine to find the distributor was bad, check that and exhaust leaks, I was at 358k when that happened and always found better uses of money then fixing my f150 (like my diesels)

Yea... my 95 has some sentimental value to me so I try to keep it running good... I ordered some shorty headers and straight piped it... it gets better mileage now but I cant keep my foot off that narrow pedal!!!

Yeah when I went long tube headers on mine I blocked off the egr, and it would always jump time and pop and shoot flames out the exhaust, not the good way that you show off either

If you have the zf5 transmission, you can do the ULTIMATE solution. A lot of the 4bt bread trucks used a Ford Small block pattern bell housing, so the engines that did got the appropriate adapter on the engine side. So a 4 cylinder cummins would bolt up, and the zf5 is pleeenty strong enough for a Cummins.

Probably would be good for 25mpg +-
