Ok so after being at the desert for awhile my truck is running really ruff. Im not sure why either. I think it could be my misfire getting worse but it just seems to convenient for it to happen while out there. The truck has a really mean shake at anything below 2500 rpm's and it has little to no power but when i gas it and get past 2500 it is fine and runs normal but anytime it dips below 2500 it bucks or shakes. Really wierd. btw its a 92 ranger 3.0 2wd manual if that helps. I need to figure this out before i start commuting again.

 

My truck was doing the same thing, and once I changed out the MAF sensor, it pretty much stopped. I also had to clean my TPS on the throttle body.

 

bad spark

 

What can you use the clean the mass air flow sensor again?

 

They sell MAF sensor cleaner at Auto Zone, Advance, and probably even Wal-Mart. Really any store that sells any auto parts should have it. Just spray a few shots on the MAF sensor and you're done. Electronic parts cleaner works well too. Whatever you use must be safe for electrical parts and leave no residue.

 

I would check your plugs and wires as well, mine did the same thing when I had plug wires reversed.

 

Sounds like a vacuum leak to me. You may have just ruptured a small line.

 

Nope Nope Nope! Lol its kinda stupid actually. All that bouncing around and jumping and a spark plug wire got pulled off. So i stuck it back on and now it runs like a champ and i cleaned the air filter and maf and now its a lot more responsive thanks guys!

 

I said plug wires lol

 

lol
