    Yippy!!!!!! My rough idle low RPM is better! it at 750 and only drops to about 650. before it would drop to close to 500-550 and be rough. So I hope it stays like this.:D

    I also took a look at the TPS sensor and did a little adjustment. theres some slack in the screw holes, and I moved it counter clock wise and tightened it. So which ever one helped, I dont know, probably both. But Im Happy!:woot::bananadance:

    Ok. That is not quite normal but better. Like you already said. HAHA. It should try to correct itself and idle up a little more. Have you done a seafoam treatment?

    650 sounds about right for the first gens, at a stop, in gear and foot on the brake. The second gens will drop to near 500, or there about.

    all i gotta do now is check my mpg's to see if they've improved. im ganna be pissed if i still am getting 12-13. Especially after doing Seafoam, Plugs, Plug wires, Fuel filter, clean MAF and TB, New PCV. I think thats it so far...

    Well guys! I just filled up and sure enough Im still getting like 13mpg's. I dont have a heavy foot and I drive perty good. But is my next thing to do to try and improve it is get a new A/F sensor? Or what?

    I know I should be getting alot better, even with my setup.

    Are you takeing into account the larger tire size? The tires you are running are 7.1% larger than the stock ones. Add 7.1% to your odo reading, then divide by the number of gallons used. Im betting that after you add the correct amount for speedo error, and extra drag from the lift and larger tires, you may be right in line with what to expect for fuel econ.

    Speedo being off doesnt matter. Use the ODO. 15 sounds about right inline with lifted 3.4 first gens..depending on how you drive.

    On the 1st gen V6 Tacos there's one sensor before the cat (AFR one) and one after the cat. Total of two, not four. Trust me I been chasing those damn things in my 02 for the past month.
