Check Engine Light!
Hey everyone i need your help. I have a 99 limited with a 3.4. since about a month after i bought my rig the check engine light has been on(about 9 months now) i bought it from a dealership and love my rig. I have now replaced the fuel filter, air filter, pcv valve, had the oil changed twice and even up graded my oil(for different reasons) a mechanic at a local toyota dealership told me that it was most likely the fuel filter, which did not fix the problem. i figured the cat was maybe plugged and needs a new one or straight piped(no emissions laws where i live) if you have any idea what the problem could be let me know. thanks!

Hey thanks for the reply the thing is is that i am do not know where to check for the codes. As far as how the truck runs it seems to run pretty good it feels a little sluggish with throttle response but i am not sure if that is how they all are

RE: Check Engine Light!
So it turned out that my check light was for a code 171 which is left bank lean. The mechanic cleaned of the carbon build up on my mass air flow sensor and turned off the light and it has yet to turn back on thanks for the help.
