20R Loss of power then power.
I have a 1980 Toy 20R 4x4. Just got it a few weeks ago and love it! It ran ok until a couple days ago then I noticed a loss of power. Maxed out 30mph in 3rd gear and had to use 4low to get up the hill to my house. Checked the plugs and it looked as if only 2 of them were firing and checked the gap. Checked the distributer and vacuume advance. Fired it back up and now I have full power. At higher RPM it will miss just a bit sometimes. Any Ideas?

I am having a similar situation with my 76. Rough idle and acceleration sometimes. Runs fine sometimes as well. However, it will not go over 63mph any more. And it takes forever to get there. I did a full basic tune up 13 months ago. Bad wires already?

The plugs were great actually. Tan tips and slight black on the outer base. I was impressed and the were all similar and cleaned before being reinstalled.

Also, the truck hit a deer about 4 months ago. Could that have done internal damage that is just now showing up? Would these be fitting symptoms for poor compression or anything? Just to add, the timing is spot on.

yes hitting a deer will for sure lower your compression. it might of damaged ur muffler bearings as well. so i think u should tear apart ur muffler and check them just my 2 cents

CJ55?
Don't give up on your '80 just yet. Try and find yourself a cheap rust bucket Toyota with a great running 20R or 22R and replace your motor.

As far as swaps go, I don't have the time or tools (or current knowledge) to do a motor swap.

Muffler bearings? Are you serious? The only logical way hitting a deer will affect how your engine is running is if it damaged the radiator, causing the engine to overheat. There are absolutely zero bearings located in a muffler, or exhaust system for that matter.
