I know this motor isn't a power house, it's just strange how some days it feels like it has much more power then others. I recently did a head gasket job on it, did everything I should have, also replaced all injectors, it did this same thing before the work was done. It idles fine 800 rpms, timing set correct, TPS checks out fine, it does at times have a slight miss through the rpm range, any ideas would be great.

Thanks

 

Just a random question, when did you last replace the oxygen sensor. I had the same problem, and traced mine back to a bad O2 sensor

 

I replaced the 02 sensor about two years ago, it was with a Bosh sensor, I've heard our trucks don't like them.

 

I have a solution just do a 5vz swap and dont spend another penny on the 3.0

 

If you got a FREE donor I'll do it.

 

Yeah well the comment was intended to shed light on how awesome this swap is and how ˟˟˟˟ty the 3vz is but where are you locted i can get some stupid cheap donors

 

x2 on the O2 sensor.... also... might wanna check out ur throttle position sensor, air flow meter, engine coolant temp sensor, look for vacuum leaks... etc... when was last time u changed ur fuel filter? Dist. cap and rotor?

 

Fuel filter was changed around 15K miles ago, I've checked the TPS and AFM, new cap, rotor and plugs, a couple years ago I took it to the dealership just to see if they could tell me the problem, they said it was restricted injectors. When I did the head gasket job I also replaced all the injectors thinking I would be golden, but after all this work I still have this issue at times.
