my 4runner has been running all out of wack lately especially when its cold. idling roughg and sort of jumping and shaking when your in the gas. Dont really know were to start since there is not an egr valve in the 97 3.4 4runner? Lost!!!! Where should i start first??

 

What was the actual code(s)?

 

i honestly not sure and will try to find out. i took it to autozone when the light came on and he just told me it threw and egr code and they didnt have that part it was threw the toyota dealership only

 

Too many potential causes. We need the exact trouble code.
