2004, 3.0 2wd Auto, 190k miles

Hi guys been awhile since I have been here but you guys have helped! Right after I finish my Christmas shopping I get a truck issue. of course!

Ok so background story, about 3 weeks ago I had a rough idling intermittently, every few days it would last about 10 minutes or so. Then finally 2 days ago, I had terrible IDLE, misfiring and a bad smell. (P0302,p0316 and misfire on 1000 revs code) That night based on advice from 10 people on FORD RANGER FANATICS, I replaced my coil pack with a BWD coil pack. My original coil pack has at LEAST 130k but could very well have 190k if it was not replaced in the first 60k. Anyways, right off the bat it was MUCH better! Better idle, much better smell but all day it wasn't perfect and now similar symptoms are back just not as rough.

So it wasn't the coil pack but it did help. Yesterday I have bank 2 sensor stuck rich and system too lean codes, these were pending codes. Now this morning we finally have set codes p0302 and p0316 and p0300. So essentially back to square one.


heads were somewhat recently done (for the second time), spark plugs and wires done in the last 50 k. I have carb cleaner to find a vacuum leak it will be my first attempt.


What could be wrong? Especially for coil pack to improve it but not fix it.



ALSO CAN I DRIVE THIS TRUCK WHILE I CHASE THIS ISSUE DOWN? I understand I am wasting gas but its my only vehicle and I need it for work
