Hi everyone,
Thanks in advance for any wise words you may have. I have an 89 4x4 pu, with a 22re motor in it. Turning over 300k km's pretty soon so it's just getting warmed up. Recently the engine has developed a 'muffled popping' (for lack of a better description) noise under acceleration. In the past it hasn't been continuous, but recently it has become a steady sound. I know this is a pretty fluffy description, but can't think of a better way to describe it.
It doesn't go through a ton of oil, but does burn it, the coolant is fine, I haven't noticed a significant loss of power... what else... Oh, I'm not particularly mechanically inclined but can figure most things out so I guess I'll start there and see what you wise souls have to say.
Thanks.

 

When was the last time you did a tune up? Plugs, wires, filters etc. etc...

 

Post a video!

Popping like popcorn?
Popping like tire pop?
Popping like I just popped you in the face?

 

I bet he means "pinging".

 

Bet it's misfiring. Let's see some pictures of your spark plugs.

 

Awesome, thanks for the responses!

Misfiring might be the best way to describe it. I can't remember when I changed the plugs and wires, but it wasn't that long ago. Maybe 12,000 km's ago. Air filter was changed pretty recently, oil changes (fairly) regularly.
I'll have a look at the plugs and see if I can try to be more informative...
Thanks for the clever deductions!
