it may work for 2 days & then not work for a week

At 125,000 miles had random misfire code 0300, 0302, 0307, and the throttle body one(don't remember number) replaced all spark plugs, still coded on 0302, replaced cylinder 2 coil and boot, still coded random misfire and cylinder 2, replaced throttle body and that code is gone but still 0300, and 0302, not sure where to go from here..............any thoughts

Checked the brake shift lock actuator and it's fine. Put it all back together and the gear shift lever is 'loose'. I can shift from Park to 1st without any problem....except, when it goes into any gear, it does not seem to 'stop' securely into any gear (like, lock into place). I'm at a loss for what to do now. I'm not real excited about driving it for fear it will no stay in gear. Also, my truck is a "Late 99".

what does that mean? where do I do that, not in book.

When vehicle warms up after a few times of slightly above normal acceleration I get a heavy exhaust smell in the cab and I see light white smoke coming from under hood it looks to be coming from close windshield in the middle. And I also get occasional white smoke out of tail pipe but not that often?!!! Help, it doesn't seem to do it all the time.can anyone tell me what is going on or what route I need to take ?!!

I have a wirer not plugged in under the hood & it looks just like the fuel tank pigtail. I noticed it when my truck would only turn over but does not start and I have trouble shot a lot of things, now I have to drop my gas tank next.

Checked fuses, all is good there. Restarted truck same issue.

When I was pulling my trailer down the road my turbo hose on the passenger side ,on my 7.3 blows off and I lose a lot of power reinstalled hose it blew off again.

it wont start (wont turn over) turn the key several times off on off on and it will finally start, or let it sit for a hr or so and it will start. i have tested what i thought was all the re-lays, starter,p/n safety switch, fuel pump pressure and relay, no engine codes, then i found out that their is another starter relay by the battery's negative post. can anyone confirm this

Steering column is real loose

And the mirror won't move now
