Any advice on what to change to restore engine power?
 

Hey guys, I just bout a 93 4x4 with the V6. Everything works real well on the car including the tranny but it has 144k miles and it really seems sluggish getting up to speed. The previous owner says he replaced the plugs, plug wires, cap, rotor, pcv valve and fuel filter. However, I can't help but wonder why the thing is so sluggish.

On previous vehicles I've had intake manifolds cleaned out to remove carbon buildup and this has helped some. Do any of you guys have any recommendations as to what I can replace to help restore some of the engine's power?


Any help would be appreciated- thanks

I wonder how long ago he replaced the spark plugs.

Or perhaps they were gapped incorrectly.

I would test or replace the plugs and also do a cylinder compression test.

Let us know how it goes.

Other then what has been done. I would change the O2 sensor. It may not throw a code, but they really should be replaced every 20-30k. Also check the cat and muffler. Good hunting.
