Huge Bang/Pop when accelerator pressed, followed by burning smell.

Jtx, lolz

Four0Sport, I've been thinking along those lines, maybe something is tight or something, and it was freeing itself? I was thinking about putting my rear end on jackstand and putting it in drive and letting it idle to work out any binds or anything, lol.

Thanks for all the input guys, I'll let you know tomorrow after I look through it.

 

[Four0Sport]

can you remember what the smell was like? most under hood fluids have a distinct smell when burning. god.. i remember when i ditched the 93 4dr i had and broke 2 wheels off.. yeah, broke off. gear oil has the worst smell.

 

[Blacksheep Josh]

Smelled smokey. Wasn't like plastic burning or something...

It was just a basic burning smell. Like smoke almost.

Best way to describe it is you know the smell when you turn your furnace on for the first time in the winter? Kinda like that for a brief period.

 

[Four0Sport]

hmm.. oil or trans fluid maybe? idk. get all the free rides from this girl youve been talking about that you can.

 

[Blacksheep Josh]

I guess best thing is to look and see where the levels are at.

I really hope the seal on teh tranny didn't go... Been there, done that all ready..

Oil right now is at about 6,000 miles, but it's synthetic. I usually replace the filter every 5k miles, and the oil every 10k. Maybe it had something to do with that...

 

[Four0Sport]

even with synpower in my 97 and maxlife in my 93 i still try to never go past 5K on oil changes.

 

[Blacksheep Josh]

Yeah, but mine is constantly leaking/using oil, about a quart a week... So it's constantly getting fresh oil... lol

 

[Four0Sport]

a quart a week isnt good.. maybe you should track that leak down while your inspecting the smell.

 

[Blacksheep Josh]

That's just it, I can't find an oil leak for the life of me. My Dad's 03 Jaguar X-type leaks more oil then mine. I've read about the rear seals being/going bad, but I've even put a piece of white posterboard underneath it and it's clean... so idk.

I couldn't find anything wrong visually, so I'm betting on a misfire/backfire.

As for the oil usage, let me clear up. Currently it's not a quart a week, it WAS with conventional, and I think I was so tired I just typed what came to mind. Since I've made the change to synthetic it's gone to about every 2-3 to needing a quart. I'm attributing the oil usage to poor maintenance by the previous owner, and also that the engine has 270k original miles...

I think this Summer I may do the V8 swap or rebuild the V6. Not sure yet, depends if I have a place to do the work.

 

[Blacksheep Josh]

Oil light came on. But it was low before the sound happened.

I drove it about 50 miles today, even slammed down the throttle at one point to see what would happen. I think it was just a really bad backfire y'all, it had to be. Either that, or as someone suggested something got binded up and released itself, idk. I'll keep an eye on it, but this is really weird... ran fine today, no smells, no popping, no nothing except the usual moans and groans of old suspension and a failing brake booster.

 

[Tbars4]

...Did you crawl under and inspect everything yet???...

 

[Willard]

So it seems like everything is fine?

I can understand this, every now and then my explorer does something that sounds completely awful and freaks me out, but it keeps going and that's all I ask.

Along these lines I used to have a problem where the front end out sort of "jump" out of nowhere like I hit a sizable bump, only it did it on perfectly smooth road. I never figured out what caused that.

When you drive a truck that's old with this many miles, they are going to do weird things. You just have to get used it, and turn the radio up louder when it starts making another noise, lol.

 

[Blacksheep Josh]

Tbars, yeah man, I did it yesterday afternoon. I see nothing wrong (well, nothing wronger then usual that is).

I'm getting back 1k from financial aid, so I'll be able to fix a bunch of the moans and groans finally...
