My 3.9 feels like there is now power at all. I just had a new cat put on my exhaust but this did not take away the problem. When i stop on the pedal there is not very much pick up at all. I have tried some fuel injector cleaner but no luck. Does any one have any ideas on what could be wrong with my truck? It is a 95 ext. cab with a auto tranny.

i think it could be the facts that youve got a v6. the neutered 5.2 just doesnt quite have enough. ive got the v6 too though so i dont have much room to talk. have you had a tune up lately? cap rotor plugs wires, might wake her up a little. air filter may be dirty, you could need new muffler, if its too bad you may have lost backpressure, well im not sure, just my $.02

Have you changed the O2 sensor lately. When I changed mine my performance improved significantly.
If you really want to improve performance get a Superchip tuner. I put one on mine and it feels like a muscle car. I have a K&N drop in filter and the Dynomax muffler. Next week I will install the 1.7 roller rockers and a F&B throttle body. Hopefuly it will really scream with these mods.

my guess would be that your new exhaust is too big. What are you running now?

They didn't say anything about getting a new exhaust system...just a cat.

All that i had done to my exhaust was replace that cat. Could the O2 senser be pluged with carbon? How much does it cost to replace one of them?

If the cat went bad, the O2 could also be in need of replacement. Any shop with a scanner can watch the O2 to see if it is working properly.

Same here
Feels like a 4 banger,Goes pretty good on the highway but getting on the highway is kinda scary.
I have a 97 x-cab V6.
Where is the sensor and how much to replace?

The O2 sensor that you need to change is on the exaust pipe between the engine and the cat. It takes a 7/8ths wrench and limber hands to disconect the plug that is snapped to the trany.
auto zone sells the Bosch sensor for about $60 bucks.

did this happen only since you had the new cat put on the truck? check t make sure they put it on right- they must go on correctly in order to flow exhaust correctly-- you may want to see if they disconnected or damaged the O2 sensors

No, it is on correclty. It ran like crap before. I installed the cat thinking it would fix the problem. I am putting on a new 02 senser in the next couple of days. Hopefully this fixes the power problem.
