Check engine light!! Never good!
Ok I got some codes on my '01 3.3 2wd
I got P0134= O2 sensor 1 in bank 1 P0154= O2 sensor 1 in bank 2 P0430= Catalyst efficiency low-bank 2 I replaced the O2's I know thats not alway what needs to be done, The dip at Auto Zone thinks my MAF needs to be replaced. I bet he does those things arent cheap. The truck Idles rough. There sounds like an exhaust leak on the driver side but cant find one? About to just ghost ride this thing and go by a Toyota!

your getting codes in in both banks so thats a sign something in the upper half of emmisions is going bad. possible mass air leak(vac hose leak) or yes even a mass air flow sensor. they do go bad. you have and intake on your truck? wet or dry filter? when you clean it last?
but its saying tell tail signs of leaking intake gaskets. running rich. rough idle poor gas mileage. gaskets maybe $30 and i would replace plugs while your there since its been idle rough they could be carboned up.

I have replaced cap, rotor, plugs, put in a drop in K&N, fuel filter, cleaned the MAF with MAF cleaning spray, I have checked a few times for leaks. It does get bad gas mileage. I might be taking it in soon to get the Knock sensor replaced. But that wont before a couple weeks.

get some starter fluid.. get the truck at idle, spray it all along the intake tube up the manifold and around all hoses and gaskets. If your idle changes at any point you have a leak. Dont give up on it yet! lol

I did that But I will try it again maybe I missed something.
Is there suposed to be a ground strap anywhere. My old Yoda had one from the Valve cover to the fire wall. I havent seen one on the Fronty. I know that if stuff isnt grounded good you have problems.
