Loss of power/misfire

Hi I’m new here but I’m in a pickle. I have a 93 yota 4Runner 5speed manual and I’m having some issues. There is a misfire and it has a loss of power when driving up hills. When I take off it’s slow getting up to speed through all five gears. I don’t even use 5th cause it’s to slow. I’ve done the thing where you take the plug off the distributor cap to see which cylinder is the problem. I’ve found the cylinders that are not firing right. So I bought plugs, distributor cap, rotor and spark plug wires but I’m still having the same issue with the same two cylinders. It doesn’t smoke but does have pretty good oil leak on the passenger side of the engine and can’t find where it’s coming from. I can smell gas really bad when driving. It has 299000 miles. Idk what else it could be. Any advice would be helpful. It’s my only ride right now so I need to find out what’s wrong with it pretty fast before it quits completely. Thanks in advance!

 

I’m going to take a shot and say Fuel Dampener if your smelling gas. Google is your friend, look it up and do some research. Also check your fuel filter attached to the frame. Right side just about where the door pillar is. If it looks original it needs to be changed.

 

Okay thanks I’ll look that up. I’ve down a lot of research but couldn’t find anything

 

Be prepared for sticker shock if you think it is, freaking little part is like $130 bucks. I had the same issue. Changed both parts (Dampener and Canister style fuel filter) and everything cleared up. You’ll also need a manifold gasket.

 

I’ve found some stuff it said it could be that or faulty fuel pressure regulator

 

Just letting you know I figured out the problem. It was fuel injectors

 

Cool man . While you’ve got it down you might want to check that dampener.

 

Bump - What about the oil leak???
